California Code, Business and Professions Code - BPC § 19165

Insulation material may only be sold or installed in the state which has been certified by the manufacturer to have been tested in accordance with standards adopted by the bureau and which bears a visible bureau approved statement by the manufacturer certifying that the insulation material meets those standards and has been tested and approved by an approved testing laboratory. The testing criteria shall be designed to determine whether insulation materials have met or exceeded minimum established standards. The bureau shall publish and periodically update a directory of certified insulation, including the R-value. The bureau shall charge a fee of fifty dollars ($50) annually, for each certified product listed in the directory up to a maximum of five thousand dollars ($5,000) per manufacturer.

Within 180 days after the date of adoption of those standards, each manufacturer of insulation material shall develop and implement a quality assurance program. Each manufacturer shall keep a record of any testing performed pursuant to the program for a period of three years after it is performed.
