(a)
					 Compliance Test Methods for HWPW, PB, and MDF. Compliance with the emission
					 standards for HWPW, PB, and MDF in section
					 93120.2(a) and,
					 if applicable, section
					 93120.3(c) or (d)
					 shall be demonstrated by conducting product emissions tests, verified by third
					 party certification as specified in section
					 93120.4 and conducted using one of
					 the following:
(1) The primary method, defined
					 as ASTM E 1333-96(2002) (large chamber test method).
(2) A secondary method, defined as specified
					 in ASTM D 6007-02, with the additional conditions specified below:
(A) The secondary method shall be operated
					 using the testing conditions and loading rates specified in ASTM D 6007-02, and
					 the conditioning time used to establish equivalence in section
					 93120.9(a)(2)(B).
					 In addition, when testing panels the secondary method shall be operated by
					 testing nine specimens representing evenly distributed portions of an entire
					 panel. The nine specimens shall be tested in groups of three specimens,
					 resulting in three test results, which shall be averaged to represent one data
					 point for the panel.
(B)
					 Equivalence between the secondary method and the primary method must be
					 established, at least once each year, by the third party certifier for each
					 testing laboratory used by the third party certifier. Minimum requirements for
					 an equivalence demonstration shall include at least ten comparison sample sets,
					 which compare the results of the primary and secondary methods. The following
					 parameters must be met in the comparison:
1.
					 For the primary method, each comparison sample shall consist of the result of
					 simultaneously testing an appropriate number of panels (factoring in the
					 loading rate) from the same batch of panels tested by the secondary
					 method.
2. For the secondary
					 method, each comparison sample shall consist of testing nine specimens
					 representing evenly distributed portions of an entire panel. The nine specimens
					 shall be tested in groups of three specimens (factoring in the loading rate),
					 resulting in three test results, which shall be averaged to represent one data
					 point for the panel, and matched to their respective primary method comparison
					 sample result.
3. The ten
					 comparison sample sets shall consist of testing a minimum of five sample sets
					 in each of at least two of the following ranges of formaldehyde concentrations,
					 as measured by the primary method:
a. Lower range:
less than 0.07
								ppm
b. Intermediate range:
0.07 to
								less than 0.15 ppm
c. Upper range:
0.15 to 0.25
								ppm
4. The average and standard deviation of the
					 difference of all comparison sets shall be calculated as follows. For each of
					 the two ranges used for testing, the following computations shall be performed:
a. Denote the number of sets in the given
					 range by
n
.
b.
					 Compute the difference between the primary and secondary method value. Denote
					 the difference for the
i
th set by
Di
, where
i
ranges
					 from 1 to
n
.
c.
					 Compute the average, x[BAR], and standard deviation,
S
, of the
					 differences according to the following formulas:

5. The secondary method shall be considered
					 equivalent to the primary method if the following condition is met for both
					 tested ranges:

where
C
is equal to:
0.026 for the lower range;
0.038 for the intermediate range; and
0.052 for the upper range.
6. Equivalence must be established between
					 the primary and secondary method to represent the range in emissions based on
					 the emission standards specified in section
					 93120.2(a) for
					 composite wood products that a third party certifier is approved to verify
					 under section
					 93120.4 and, if applicable, the
					 range in emissions for no-added formaldehyde based resins or ULEF
					 resins.
(3) An
					 alternate secondary test procedure may also be used as specified in sections
					 93120.9(a)(3)(A)
					 through 93120.9(a)(3)(C).
(A) Chamber test methods other than ASTM E
					 1333-96(2002) (large chamber test method) may be used if they are demonstrated,
					 following the minimum requirements specified in section
					 93120.9(a)(2)(B),
					 to provide equivalent results to those obtained using ASTM E 1333-96(2002). All
					 alternative secondary test methods must be approved in writing by the Executive
					 Officer prior to use as specified below.
(B) An application to use an alternative
					 secondary test method must be submitted to the ARB in writing, and must
					 include, at a minimum, the following information and data:
1. A complete description of the test method
					 used to quantify product emissions, including all procedures used, precision
					 and reproducibility, and the criteria used to demonstrate the validity of the
					 test method.
2. Results collected
					 using the alternate secondary test method and corresponding equivalent
					 emissions.
(C) Within 45
					 days of receipt of an application, the Executive Officer shall notify the
					 applicant in writing that the application is complete, or if additional
					 information or testing is required to complete the application. If the
					 Executive Officer finds that an application complies with the requirements of
					 this section, then he or she may issue an Executive Order certifying that the
					 alternate secondary test procedure provides equivalent results to ASTM E
					 1333-96 (2002), and authorize its use for compliance
					 testing.
