Abstract
The Environmental Protection Agency (EPA) is proposing to update the incorporation by reference of several voluntary consensus standards in the Agency's formaldehyde standards for composite wood products regulations under the Toxic Substances Control Act (TSCA) due to the standards having been updated or superseded by the issuing organizations. These new standards primarily update test methods and product standards concerning composite wood products that use formaldehyde. EPA is also proposing to conform these updated standards in the scope and definitional sections in the final rule and to incorporate by reference a new small scale quality control chamber test method, similar to current methods already incorporated by reference.

B. What is the Agency's authority for taking this action?
EPA is proposing this rule pursuant to the authority in section 601
of TSCA, 15 U.S.C. 2697, relating to formaldehyde emission standards
for composite wood products.
C. What action is the Agency taking?
The Agency is proposing to update the Incorporation-By-Reference
(IBR) for certain voluntary consensus standards in 40 CFR 770.99 to
reflect the most current standards issued by the relevant standards
organizations. EPA is also proposing to conform these voluntary
consensus standards in the scope and definitional sections of 40 CFR
part 770. In addition, EPA is proposing to incorporate by reference at
40 CFR 770.99 an additional small scale quality control chamber test
method, ISO 12460-2:2024(en).
D. Why is the Agency taking this action?
The Agency is proposing this action to update the incorporation by
reference for several voluntary consensus standards at 40 CFR 770.99 to
their current editions to address outdated, superseded, and withdrawn
standards that have been updated between 2022 and 2024. These updates
are needed because several of the standards in 40 CFR 770.99 are
outdated. EPA is also proposing to conform these voluntary consensus
standards in the scope and definitional sections of 40 CFR part 770 to
reflect the current editions that must be used by regulated entities,
if finalized as proposed. EPA is also proposing to incorporate by
reference at 40 CFR 770.99 an additional small scale quality control
chamber test method, ISO 12460-2:2024(en).
E. What are the incremental economic impacts?
EPA anticipates no additional costs to stakeholders associated with
this notice of proposed rulemaking for updated standards. This is a
routine action that proposes to update outdated voluntary consensus
standards incorporated by reference at 40 CFR part 770.
II. Background
A. Regulatory Overview
1. Formaldehyde Emission Standards for Composite Wood Products
The Formaldehyde Standards for Composite Wood Products Act of 2010
(Pub. L. 111-199, 124 Stat. 1359) created Title VI of TSCA (15 U.S.C.
2697), established emission standards for formaldehyde from composite
wood products, and directed EPA to implement and enforce a number of
provisions covering composite wood products. On December 12, 2016, EPA
published a final rule (2016 final rule) (Ref. 1) to reduce exposure to
formaldehyde emissions from certain wood products produced domestically
or imported into the United States. EPA worked with the California Air
Resource Board (CARB) to help align the 2016 final rule with the
Airborne Toxics Control Measure (ATCM) (Ref. 2) to the extent EPA
deemed appropriate and practical considering TSCA Title VI. By
including provisions for laminated products, product-testing
requirements, labeling, recordkeeping, and import certification, the
2016 final rule requires that hardwood plywood, medium-density
fiberboard, and particleboard products sold, supplied, offered for
sale, imported to, or manufactured in the United States be in
compliance with the emission standards. The 2016 final rule also
established a third-party certification program for laboratory testing
and oversight of formaldehyde emissions from manufactured and/or
imported composite wood products.
2. 2018 Voluntary Consensus Standards Amendment
On February 7, 2018, EPA published a final rule (Ref. 3) to update
several voluntary consensus standards incorporated by reference at 40
CFR 770.99. These updates applied to emission testing methods and
regulated composite wood product construction characteristics. Several
of the organizations that develop voluntary consensus standards (i.e.,
technical specifications for products or processes developed by
standard-setting bodies) had updated, superseded, and/or withdrawn
their standards through the
[[Page 6163]]
normal course of business to take into account new information,
technology, and methodologies.
3. 2019 Technical Issues Amendment
On August 21, 2019, EPA amended 40 CFR part 770 via a final rule
(2019 final rule) (Ref. 4) to address certain technical issues. The
2019 final rule:
<bullet> Further aligned testing requirements with the CARB ATCM;
<bullet> Clarified provisions addressing non-complying lots and how
those provisions apply to fabricators, importers, retailers, and
distributors who are notified by panel producers that composite wood
products they were supplied are found to be non-compliant after those
composite wood products have been further fabricated into component
parts or finished goods;
<bullet> Clarified that regulated composite wood products and
finished goods containing composite wood products must be labeled at
the point of manufacture or fabrication, and if imported, the label
must be applied to the products as a condition of importation;
<bullet> Addressed TSCA Title VI ``manufactured-by'' date issues;
and
<bullet> Updated two voluntary consensus standards that were
incorporated by reference in 40 CFR 770.99.
4. 2023 Voluntary Consensus Standards Amendment
On February 21, 2023, EPA published a final rule (2023 final rule)
(Ref. 5) that amended 40 CFR part 770 to, among other things:
<bullet> Update the incorporation by reference for ten voluntary
consensus standards to reflect the current editions that are in use by
regulated entities and industry stakeholders. These updates were needed
to ensure continued consistency with the standards adopted and used by
industry.
<bullet> Allow for remote inspections in the event of unsafe
conditions that would prevent a third-party certifier (TPC) from
traveling in-person to the area. During the COVID-19 public health
emergency, EPA provided temporary flexibility to allow TPCs to conduct
remote inspections to satisfy the requirements of the rule. EPA made
this flexibility permanent and allowed TPCs to conduct the required
initial on-site inspection or quarterly inspections and sample
collections remotely when in-person, on-site inspections are
temporarily infeasible because of unsafe conditions.
<bullet> Include certain technical corrections and updates to
create additional flexibilities for the third-party certification
process, as well as clarifying language as it relates to the production
of wood products. Those corrections better aligned EPA's rule with the
CARB requirements.
B. Proposed Amendments
1. Voluntary Consensus Standards IBR Update
a. IBR Update
EPA is proposing to update the IBR of certain voluntary consensus
standards in 40 CFR 770.99 to reflect the most recent editions of the
following standards assembled by the American National Standards
Institute (ANSI), the American Society for Testing and Materials
(ASTM), the British Standards Institute (BSI), the International
Organization for Standardization (ISO), and the National Institute of
Standards and Technology (NIST):
i. Product Standard for Structural Glued Laminated Timber (ANSI A190.1-
2022)
This standard was initiated by the Engineered Wood Association
(APA) and approved through ANSI. The ANSI standard details the specific
requirements for production, inspection, testing and certification of
structural glued laminated timber. The standard also describes a
quality control system for the laminator, which covers plant
qualification, daily quality control, product marking, and the
functions of an accredited inspection agency. ANSI last updated this
standard on February 17, 2022 (Ref. 6). EPA proposes to update the
version of the standard incorporated by reference in 40 CFR 770.99 from
ANSI A190.1-2017 to ANSI A190.1-2022.
ii. Standard Test Method for Determining Formaldehyde Levels From Wood
Product Using a Desiccator (ASTM D5582-22)
This standard was issued by ASTM and identifies procedures for
testing formaldehyde emission potential from wood products by measuring
airborne formaldehyde after samples of a specified surface area are
placed in a small distilled water reservoir within a closed desiccator
for 2 hours. The ASTM standard was last updated in August 2022 (Ref.
7). EPA proposes to update the version of the standard incorporated by
reference in 40 CFR 770.99 from ASTM D5582-14 to ASTM D5582-22.
iii. Standard Test Method for Determining Formaldehyde Concentrations
in Air From Wood Products Using a Small-Scale Chamber (ASTM D6007-22)
This standard was issued by ASTM and describes the procedure for
using a small-scale chamber test method to measure formaldehyde
concentrations in air emitted by wood product test specimens under
defined test conditions of temperature and relative humidity. Results
from the small-scale method are intended to be comparable to results
obtained from testing larger samples using the large chamber test
method, described in ASTM E1333. This ASTM standard was last updated in
August 2022 (Ref. 8). EPA proposes to update the version of the
standard incorporated by reference in 40 CFR 770.99 from ASTM D6007-14
to ASTM D6007-22.
iv. Standard Test Method for Determining Formaldehyde Concentrations in
Air and Emission Rates From Wood Products Using a Large Chamber (ASTM
E1333-22)
This standard was issued by ASTM and describes the procedure for
using a large chamber test method to measure formaldehyde concentration
in air and emission rate from wood products under conditions designed
to simulate product use, while maintaining specific test conditions of
temperature and relative humidity. The standard was last updated in
August 2022 (Ref. 9). EPA proposes to update the version of the
standard incorporated by reference in 40 CFR 770.99 from ASTM E1333-14
to ASTM E1333-22.
v. Wood-Based Panels--Determination of Formaldehyde Release--Part 3:
Gas Analysis Method (BS EN ISO 12460-3:2023)
This standard was approved through ISO and BSI and describes a
procedure for determination of accelerated formaldehyde release from
wood-based panels. The standard was last updated in September 2023
(Ref. 10). EPA proposes to update the version of the standard
incorporated by reference in 40 CFR 770.99 from BS EN ISO 12460-3:2020
to BS EN ISO 12460-3:2023.
vi. Wood-Based Panels--Determination of Formaldehyde Release--Part 3:
Gas Analysis Method (ISO 12460-3:2023(E))
This standard was approved through ISO and describes a procedure
for determination of accelerated formaldehyde release from wood-based
panels. ISO 12460-3:2023(E) is identical to BS EN ISO 12460-3:2023.
This version was incorporated to avoid potential confusion by regulated
[[Page 6164]]
stakeholders and allow manufacturers to choose which standard to use in
each respective country. The standard was last updated in September
2023 (Ref. 11). EPA proposes to update the version of the standard
incorporated by reference in 40 CFR 770.99 from ISO 12460-3:2020(E) to
ISO 12460-3:2023(E).
vii. Structural Plywood (PS 1-22)
This standard was issued by NIST and describes the principal types
and grades of structural plywood, covering the wood species, veneer
grading, adhesive bonds, panel construction and workmanship, dimensions
and tolerances, marking, moisture content and packaging of structural
plywood intended for construction and industrial uses. Test methods to
determine compliance and a glossary of trade terms and definitions are
included, as is a quality certification program involving inspection,
sampling, and testing of products identified as complying with this
standard by qualified testing agencies. The NIST standard was last
updated on October 2, 2023 (Ref. 12). EPA proposes to update the
version of the standard incorporated by reference in 40 CFR 770.99 from
PS 1-19 to PS 1-22.
b. Addition of ISO 12460-2:2024(en) as an Alternative Quality Control
Test Method
EPA is proposing to add ISO 12460-2:2024(en), Wood-based panels--
Determination of Formaldehyde Release--Part 2: Small-scale Chamber
Method (Ref. 13), as a quality control test method in 40 CFR
770.20(b)(1) and to IBR the standard in 40 CFR 770.99. This standard
was approved through ISO and describes the procedure for using a small-
scale chamber test method to test formaldehyde emissions from wood
products under defined test conditions of temperature, relative
humidity, loading and air exchange rate by measuring the concentrations
of formaldehyde in air from samples of a specified surface area. This
standard is a small scale quality control chamber test method that EPA
is proposing to incorporate by reference as an allowable alternative
quality control test method, due to its similarity to other standards
currently incorporated by reference for quality control methods, and to
allow regulated entities to make use of the wider range of analytical
methods the standard allows, such as laser absorption spectroscopy.
Industry has requested including the latest testing methodology
which allows for greater industry flexibility in choosing quality
control methods that best fit their circumstances. Proposing this
additional standard also aligns with the CARB ATCM, which recently
incorporated ISO 12460-2:2024(en) as a valid small scale quality
control chamber test method. EPA believes that this action is warranted
to facilitate regulated entities using the most up-to-date voluntary
consensus standards to comply with the regulation at 40 CFR part 770 as
well as align with current CARB requirements. Based on its similarity
to other standards currently incorporated by reference for quality
control methods and requests from industry to include the latest
testing methodology, EPA proposes to add this new ISO standard as a
quality control method in 40 CFR 770.20(b)(1) and to incorporate it by
reference in 40 CFR 770.99.
EPA will initiate additional notice-and-comment rulemaking when
necessary to reflect any future changes to voluntary consensus
standards incorporated by reference in 40 CFR 770.99.

2. Technical Correction(s)
To conform to the proposed list of updated standards and the
addition of one new standard listed in in sections II.B.1.a. and
II.B.1.b. of SUPPLEMENTARY INFORMATION, EPA is proposing to update 40
CFR 770.1 and 770.3 to reflect the standards that EPA proposes to
incorporate by reference in 40 CFR 770.99.
C. Rationale for Proposed Changes
EPA is proposing to update the incorporation by reference of
certain voluntary consensus standards in 40 CFR 770.99 that have been
updated, superseded, or withdrawn by the issuing organizations. These
new standards are needed to reflect the most recent editions of those
standards issued by the relevant standards organizations. EPA is also
proposing the addition of a new standard, ISO 12460-2:2024(en), to
allow industry greater flexibility in choosing quality control methods
that best fit their circumstances, such as laser absorption
spectroscopy. This additional standard also aligns with the CARB ATCM,
which recently incorporated ISO 12460-2:2024(en) as a valid small scale
quality control chamber test method. EPA believes that this action is
warranted to facilitate regulated entities using the most up-to-date
voluntary consensus standards to comply with the regulation at 40 CFR
part 770 as well as align with current CARB requirements.
III. Request for Comments
When necessary, EPA intends to reflect any future changes to
voluntary consensus standards incorporated by reference in 40 CFR
770.99 through additional notice-and-comment rulemaking. EPA is seeking
public comment on the proposed updates to these standards, as well as
additional standards that should be considered relevant or standards
that may soon be updated that are not currently listed as part of this
proposed rule, especially where their incorporation into future updates
could allow regulated entities the flexibility to use newer standards
that reflect industry best practices. EPA would also be interested in
receiving feedback on any realized or expected cost savings or TSCA
compliance efficiencies that might be realized with the adoption of
these new standards.
EPA also is specifically seeking comments from stakeholders under
TSCA Title VI regarding the new small scale quality control chamber
test method, ISO 12460-2:2024(en), that is being proposed. EPA is also
seeking comment from stakeholders under TSCA Title VI on the British
Standards Institute standard BS EN ISO 12460-3:2023, specifically
regarding whether this standard should be retained in the final rule or
whether BS EN ISO 12460-3 should be removed as an incorporated
standard, given that an identical, international version (ISO 12460-
3:2023) is also proposed for incorporation into the rule.

V. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at <a href="https://www.epa.gov/laws-regulations/laws-and-executive-orders">https://www.epa.gov/laws-regulations/laws-and-executive-orders</a>.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action under Executive
Order 12866 (58 FR 51735, October 4, 1993) and was therefore not
submitted to the Office of Management and Budget (OMB) for review under
Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011).
B. Executive Order 14192: Unleashing Prosperity Through Deregulation
This action is not expected to be an Executive Order 14192 (90 FR
9065, January 31, 2025) regulatory action because this action is not
significant under Executive Order 12866.
C. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden
under the PRA, 44 U.S.C. 3501 et seq. Burden is defined in 5 CFR
1320.3(b). This action does not create any new reporting or
recordkeeping obligations. OMB previously approved the information
collection activities contained in the existing regulations and
assigned OMB control number 2070-0185.
D. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA, 5
U.S.C. 601 et seq. In making this determination, EPA concludes that the
impact of concern for this action is any significant adverse economic
impact on small entities, and
[[Page 6166]]
the Agency is certifying that this action will not have a significant
economic impact on a substantial number of small entities because the
proposed rule would update incorporation by reference of voluntary
consensus standards in 40 CFR part 770 by adopting the most current
versions of those standards and by adding one new voluntary consensus
standard as a quality control test method. The updated versions of the
standards are substantially similar to the previous versions. EPA
expects that many small entities are already complying with the updated
versions of the proposed standards listed Unit II.B. This action would
allow these entities the flexibility to use the most up to date
versions of the standards instead of using outdated versions that do
not reflect industry best practice. This action also adds one new
voluntary consensus standard as a quality control test method in 40 CFR
770.20(b)(1), which regulated entities may opt to use in lieu of the
other approved quality control methods, thereby increasing regulatory
flexibility. We have therefore concluded that this action will have no
net regulatory burden for all directly regulated small entities.
E. Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate of $100 million
(in 1995 dollars and adjusted annually for inflation) or more as
described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or
uniquely affect small governments. The action imposes no enforceable
duty on any state, local or tribal governments. As discussed in Unit
V.D., the proposed rule would impose no net regulatory burdens on the
private sector.
F. Executive Order 13132: Federalism
This action does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999) because it will
not have substantial direct effects on the states, on the relationship
between the national government and the states, or on the distribution
of power and responsibilities among the various levels of government.
G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000), because it will
not have substantial direct effects on tribal governments, on the
relationship between the Federal government and the Indian tribes, or
on the distribution of power and responsibilities between the Federal
government and Indian tribes. Thus, E.O. 13175 does not apply to this
action.
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997),
as applying only to those regulatory actions that concern environmental
health or safety risks that the Agency has reason to believe may
disproportionately affect children, per the definition of ``covered
regulatory action'' in section 2-202 of Executive Order 13045. This
action is not subject to Executive Order 13045 because it does not
concern an environmental health risk or safety risk. Since this action
does not concern human health, EPA's Policy on Children's Health also
does not apply.
I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211 (66 FR 28355,
May 22, 2001), because it is not a significant regulatory action under
Executive Order 12866.
J. National Technology Transfer and Advancement Act (NTTAA)
This action involves voluntary standards under NTTAA section 12(d),
15 U.S.C. 272. EPA is proposing to adopt the use of ANSI A190.1-2022,
ASTM D5582-22, ASTM D6007-22, ASTM E1333-22, BS EN ISO 12460-3:2023,
ISO 12460-3:2023(E), ISO 12460-2:2024(en) and PS 1-22. Additional
information about these standards, including how to access them, is
provided in Unit II.B.1. of SUPPLEMENTARY INFORMATION. The following
standards appear in the amendatory text of this document and have
already been approved for the locations in which they appear: ANSI
A135.4-2012, ANSI A135.5-2012, ANSI A135.6-2012, ANSI A135.7-2012,
ANSI/HPVA HP-1-2020, ISO/IEC 17011:2017(E), ISO/IEC 17020:2012(E), ISO/
IEC 17025:2017(E), ISO/IEC 17065:2012(E), and PS 2-18. No changes are
proposed to the currently-approved IBR material.

PART 770--FORMALDEHYDE STANDARDS FOR COMPOSITE WOOD PRODUCTS
0
1. The authority citation for part 770 continues to read as follows:
Authority: 15 U.S.C. 2697(d).
0
2. Amend Sec. 770.1 by revising paragraphs (c)(3) and (7) to read as
follows:
Sec. 770.1 Scope and applicability.
* * * * *
(c) * * *
(3) Structural plywood, as specified in PS 1-22 (incorporated by
reference, see Sec. 770.99).
* * * * *
(7) Glued laminated lumber, as specified in ANSI A190.1-2022,
Standard for Wood Products--Structural Glued Laminated Timber
(incorporated by reference, see Sec. 770.99).
* * * * *
0
3. Amend Sec. 770.3 by revising the definitions for ``Hardboard'',
``Hardwood plywood'', and ``Quality control limit or QCL'' to read as
follows:
Sec. 770.3 Definitions
* * * * *
Hardboard means a composite panel composed of cellulosic fibers,
consolidated under heat and pressure in a hot press by: A wet process;
or a dry process that uses a phenolic resin, or a resin system in which
there is no formaldehyde as part of the resin cross-linking structure;
or a wet formed/dry pressed process; and that is commonly or
commercially known, or sold, as hardboard, including any product
conforming to one of the following ANSI standards: Basic Hardboard
(ANSI A135.4-2012) (incorporated by reference, see Sec. 770.99),
Prefinished Hardboard Paneling (ANSI A135.5-2012) (incorporated by
reference, see Sec. 770.99), Engineered Wood Siding (ANSI A135.6-2012)
(incorporated by reference, see Sec. 770.99), or Engineered Wood Trim
(ANSI A135.7-2012) (incorporated by reference, see Sec. 770.99). There
is a rebuttable presumption that products emitting more than 0.06 ppm
formaldehyde as measured by ASTM E1333-22 (incorporated by reference,
see Sec. 770.99)
[[Page 6167]]
or ASTM D6007-22 (incorporated by reference, see Sec. 770.99) are not
hardboard.
* * * * *
Hardwood plywood means a hardwood or decorative panel that is
intended for interior use and composed of (as determined under ANSI/
HPVA HP-1-2020 (incorporated by reference, see Sec. 770.99)) an
assembly of layers or plies of veneer, joined by an adhesive with a
lumber core, a particleboard core, a medium-density fiberboard core, a
hardboard core, a veneer core, or any other special core or special
back material. Hardwood plywood does not include military-specified
plywood, curved plywood, or any plywood specified in PS 1-22
(incorporated by reference, see Sec. 770.99), or PS 2-18 (incorporated
by reference, see Sec. 770.99). In addition, hardwood plywood includes
laminated products except as provided at Sec. 770.4.
* * * * *
Quality control limit or QCL means the value from the quality
control method test that is the correlative equivalent to the
applicable emission standard based on the ASTM E1333-22 method
(incorporated by reference, see Sec. 770.99) or, upon showing
equivalence in accordance with Sec. 770.20(d), the ASTM D6007-22
method (incorporated by reference, see Sec. 770.99).
* * * * *
0
4. Amend Sec. 770.7 by revising paragraphs (a)(5)(i)(D) and (F),

The nine specimens must be tested in groups of three specimens,
resulting in three data points, which must be averaged to represent one
test value for the panel those specimens represent.
* * * * *
(d) Equivalence or correlation. Equivalence between ASTM E1333-22
(incorporated by reference, see Sec. 770.99) and ASTM D6007-22
(incorporated by reference, see Sec. 770.99) must be demonstrated by
EPA TSCA Title VI TPCs at least once each year or whenever there is a
significant change in equipment, procedure, or the qualifications of
testing personnel, or reason to believe that the equivalence is no
longer valid. Equivalence may be demonstrated between several similar
model or size and construction ASTM E1333-22 (incorporated by
reference, see Sec. 770.99) and ASTM D6007-22 (incorporated by
reference, see Sec. 770.99) apparatuses located in the same EPA TSCA
Title VI TPC laboratory. Once equivalence has been established for
three consecutive years, equivalence must be demonstrated every two
years or whenever there is a significant change in equipment,
procedure, or the qualifications of testing personnel. Correlation
between ASTM E1333-22 (incorporated by reference, see Sec. 770.99) or,
upon a showing of equivalence in accordance with paragraph (d) of this
section, ASTM D6007-22 (incorporated by reference, see Sec. 770.99)
and any other test method used for quality control testing must be
demonstrated by EPA TSCA Title VI TPCs or panel producers,
respectively, before the certification of composite wood products, and
then whenever there is a significant change in equipment, procedure,
the qualifications of testing personnel, or reason to believe that the
correlation is no longer valid. Correlation may be established between
several similar model or size and construction mill quality control
test methods defined in paragraph (b)(1) of this section located at any
one physical mill quality control testing laboratory to the EPA TSCA
Title VI TPC's laboratory's ASTM E1333-22 (incorporated by reference,
see Sec. 770.99) and/or ASTM D6007-22 (incorporated by reference, see
Sec. 770.99) apparatus. If the TPC laboratory's ASTM E1333-22 or
equivalent ASTM D6007-22 test chamber is used for panel producer
quality control testing, no correlation as determined in paragraph
(d)(2) of this section would be required. Equivalence and correlation
sample selection should be conducted in accordance with paragraph
(c)(2)(iv) of this section.
(1) Equivalence between ASTM E1333-22 and ASTM D6007-22 when used
by the TPC for quarterly testing. Equivalence must be demonstrated for
at least five comparison sample sets in each range tested by the TPC,
which compare the results of the two methods. Equivalence must be
demonstrated for any ranges listed in paragraph (d)(1)(iv) of this
section that represent the formaldehyde emissions of composite wood
products tested by the TPC.
(i) * * *
(A) For the ASTM E1333-22 method (incorporated by reference, see
Sec. 770.99), each comparison sample must consist of the result of
testing panels, using the applicable loading ratios specified in the
ASTM E1333-22 method (incorporated by reference, see Sec. 770.99),
from similar panels of the same product type tested by the ASTM D6007-
22 method (incorporated by reference, see Sec. 770.99).
(B) For the ASTM D6007-22 method (incorporated by reference, see
Sec. 770.99), each comparison sample shall consist of testing
specimens representing portions of panels similar to the panels tested
in the ASTM E1333-22 method (incorporated by reference, see Sec.
770.99) and matched to their respective ASTM E1333-22 method
(incorporated by reference, see Sec. 770.99) comparison sample result.
The ratio of air flow to sample surface area specified in ASTM D6007-22
(incorporated by reference, see Sec. 770.99) must be used.
[[Page 6169]]
(C) The five comparison sample must consist of testing a minimum of
five sample sets as measured by the ASTM E1333-22 method (incorporated
by reference, see Sec. 770.99).
(ii) Average and standard deviation. The arithmetic mean, X, and
standard deviation, S, of the difference of all comparison sets must be
calculated as follows:
[GRAPHIC] [TIFF OMITTED] TP11FE26.001
Where X = arithmetic mean; S = standard deviation; n = number of
sets; Di = difference between the ASTM E1333-22 and ASTM D6007-22
method (incorporated by reference, see Sec. 770.99) values for the
i th set; and i ranges from 1 to n.
(iii) Equivalence determination. The ASTM D6007-22 method
(incorporated by reference, see Sec. 770.99) is considered equivalent
to the ASTM E1333-22 method (incorporated by reference, see Sec.
770.99) if the following condition is met:
[verbar]X[verbar] + 0.88S <= C
Where C is equal to:
0.026 for the lower range;
0.038 for the intermediate range; and
0.052 for the upper range.
* * * * *
(2) Correlation between ASTM E-1333-22 (incorporated by reference,
see Sec. 770.99), or equivalent ASTM D6007-22 (incorporated by
reference, see Sec. 770.99), and any quality control test method.
Correlation must be demonstrated by establishing an acceptable
correlation coefficient (``r'' value) or following the threshold
approach at paragraph (d)(2)(i)(B) of this section.
(i) Correlation. The correlation must be based on a minimum sample
size of five data pairs and a simple linear regression (unless the
threshold approach at paragraph (d)(2)(i)(B) of this section is used)
where the dependent variable (Y-axis) is the quality control test value
and the independent variable (X-axis) is the ASTM E1333-22
(incorporated by reference, see Sec. 770.99) test value or, upon a
showing of equivalence in accordance with paragraph (d) of this
section, the equivalent ASTM D6007-22 (incorporated by reference, see
Sec. 770.99) test value. Either composite wood products or
formaldehyde emissions reference materials can be used to establish the
correlation.
(A) Cluster Approach. A panel producer may work with its EPA TSCA
Title VI TPC to develop a correlation and linear regression between the
TPC's ASTM E1333-22 (incorporated by reference, see Sec. 770.99) or
equivalent ASTM D6007-22 (incorporated by reference, see Sec. 770.99)
test method and the panel producer's quality control method under
paragraph (b) of this section. In the event of clustered test results,
a panel producer may fit a line through a point near the origin (the
intersection of the X and Y axes) and the average value of the
clustered data pairs. The point near the origin should represent the
value for the EPA TSCA Title VI TPC's ASTM E1333-22 (incorporated by
reference, see Sec. 770.99) or equivalent ASTM D6007-22 (incorporated
by reference, see Sec. 770.99) test method and the panel producer's
quality control method under Sec. 770.20(b) when each testing
apparatus is empty or when a very low emitting sample is tested. The
average value of the clustered data pairs represents the average of a
minimum of five data pairs that compare the test results of the EPA
TSCA Title VI TPC's ASTM E1333-22 (incorporated by reference, see Sec.
770.99) or equivalent ASTM D6007-22 (incorporated by reference, see
Sec. 770.99) test method with the panel producer's quality control
method under paragraph (b) of this section. The line between the point
near the origin and the average value of the cluster provides the
linear regression. This line may be used by the panel producer and TPC
to develop a quality control limit for the product.
(B) Threshold Approach. As an alternative to the linear regression
and cluster approaches, a panel producer may use the average value of
the clustered data pairs from the EPA TSCA Title VI TPC's ASTM E1333-22
(incorporated by reference, see Sec. 770.99) or equivalent ASTM D6007-
22 (incorporated by reference, see Sec. 770.99) test method and the
panel producer's quality control method under paragraph (b) of this
section as the quality control limit for the product. In this approach,
no linear regression line is established. The average value would be
assigned as the upper quality control limit for production of the
subject composite wood product and must be below the applicable
emission standard.
