(a) For the purpose of compliance with this regulation only a single model of an indoor air cleaning device within a model group, if one exists, must be evaluated under the test methods.

(b) Testing of indoor air cleaning devices to determine compliance with the requirements of this article shall be performed following the ANSI/UL Standard 867 or ANSI/UL Standard 507, whichever is applicable, in their entirety, which are hereby incorporated by reference as defined in Section 94801. In-duct air cleaning devices shall be tested for electrical safety according to CSA C22.2 no. 187-20 or ANSI/UL Standard 867, which are hereby incorporated by reference as defined in Section 94801. Dual-function appliances with a primary purpose other than air cleaning, that include an air cleaning component that meets the definition of an indoor air cleaning device given in Section 94801, shall meet the applicable ANSI/UL electrical safety standard for its primary purpose, including ANSI/UL Standards 73, 153, 484, 499, 998, 1017, 1278, 1598, 1993, and 1995, which are hereby incorporated by reference as defined in Sections 94801(a)(3c), 94801(a)(3e), 94801(a)(3d), 94801(a)(3f), 94801(a)(3g), 94801(a)(3h), 94801(a)(3i), 94801(a)(3j), 94801(a)(3k), and 94801(a)(3l), respectively.

(c) Ozone emissions from indoor air cleaning devices, except for in-duct air cleaners, will be determined using the method described in Section 40 of ANSI/UL Standard 867. Ozone emissions from in-duct air cleaners shall be determined using the method described in Sections 7.5 and 7.6 of CSA C22.2 no. 187-20. For certain in-duct devices, testing under ANSI/UL Standard 867 may also be acceptable; such tests must be pre-approved by the testing laboratory and by CARB. In accordance with ANSI/UL Standard 867 test procedures, devices must be tested with filters removed, unless the device has a permanent filter, as defined in section 94801(a)(31).

(d) Electrical safety testing of indoor air cleaning devices must be conducted by a laboratory currently recognized as an NRTL by the U. S. Occupational Safety and Health Administration (OSHA), to perform testing for the entire ANSI/UL Standard 867, CSA C22.2 no. 187-20, ANSI/UL Standard 507, or other UL or ANSI/UL Standard, as applicable, and when the NRTL is operating within its NRTL Scope of Recognition. Independent laboratories qualified and operating under surveillance by an NRTL may also conduct the electrical safety testing.

(e) Ozone testing to ANSI/UL Standard 867 Section 40 or CSA C22.2 no. 187-20 Sections 7.5 and 7.6, as required in this regulation, may only be performed by an NRTL or an independent testing laboratory qualified and under supervision by an NRTL provided the testing laboratory has passed a CARB audit to verify their ability to accurately perform the ozone emissions testing procedure. The CARB audit may include, but is not necessarily limited to, review of written test protocol operating procedures, test chamber and analyzer configuration, background ozone measurements, air exchange rate, ozone half-life test results, equipment calibration and maintenance records, and other related information. Initial approval of the laboratory will also require an onsite review. CARB approval of the laboratory will be for a minimum of one year and may include a requirement for annual submittal of internal audit reports on the ANSI/UL Standard 867 Section 40 or CSA C22.2 no. 187-20 Sections 7.5 and 7.6 test protocols and the performance of the chamber(s) in which ANSI/UL Standard 867 Section 40 or CSA C22.2 no. 187-20 Sections 7.5 and 7.6 tests are conducted, and any related follow up internal audit reports. Subsequent audits may be required in order to maintain CARB approval to conduct ozone testing for the purposes of this regulation.
