Cal. Code Regs. tit. 19 § 1211
Persons wishing to submit a flame-retardant chemical for registration by the State Fire Marshal shall first obtain standard fabrics in accordance with the provisions of this section. For exterior chemicals a 10-ounce double filling grey duck (Federal Specification CCC-D-761, February, 1933) will be used, while for interior chemical a #250 cotton drill dyed blue Pontamine 4GLN (or its equivalent) color index #533 will be the standard.
Chemicals intended for the treatment of synthetics such as acetate, nylon, Orlon and Dacron, and various fiber mixtures, shall be tested as applied to appropriate fabrics made of such fibers or mixtures.
The concern submitting the sample for test may desize the standard exterior fabric before application of the chemical if it so desires. If this is done, however, the chemical will then be registered only for use on unsized or desized fabrics. This is based on the premise that a chemical which is effective on sized material will be at least equally effective on unsized material, but that the reverse is not necessarily true. If the concern desires to submit its chemical for test on desized material, the entire sample of standard fabric shall be desized before any portion of it is treated with chemical or cut for testing.
