16 C.F.R. § 1610.32 General requirements.
Title 16 - Commercial Practices
(a) No article of wearing apparel or fabric subject to the act and regulations shall be marketed or handled if such article or fabric, when tested according to the procedures prescribed in section 4(a) of the act, is so highly flammable as to be dangerous when worn by individuals. (b) The provisions of §1610.4(g)(7) of the Standard for the Flammability of Clothing Textiles, relating to results of testing, shall be applied to tests of fabrics and articles of wearing apparel subject to the Standard. To compute the average time of flame spread for each set of five specimens, at least two of the specimens must ignite and burn the stop cord for the specimen. However, if fewer than two specimens of any given set of five ignite and burn the entire length of the specimen, test results shall be interpreted according to the provisions of paragraphs (b)(1) through (b)(4) of this section. (1) If no specimen ignites and burns the stop cord, the results of that test shall be regarded as Class 1 (passing). (2) If only one of five specimens of a plain surface fabric ignites and burns the stop cord with a time of 3.5 seconds or more, the results of that test shall be regarded as Class 1 (passing). (3) If only one of five specimens of a raised-fiber surface fabric ignites and burns in less than 4 seconds, but the base does not ignite or fuse, the results of that test shall be regarded as Class 1 (passing). If only one of five specimens of a raised-fiber surface fabric ignites or burns in more than 4 seconds, regardless of whether the base fabric ignites or fuses, the results of that test shall be regarded as Class 1 (passing). (4) If only one specimen ignites and burns the stop cord in less than 3.5 seconds for plain-surface fabrics or less than 4.0 seconds for raised-fiber surface fabrics where the base fabric ignites or fuses, test another set of five specimens. See §1610.4(g)(7). Compute the average time of flame spread for all 10 specimens. If two or more of the specimens ignite and burn the stop cord, average the results from all specimens which ignited and burned the stop cord. See §§1610.3(a)(3) and 1610.4(g)(7). If only one of the ten specimens ignites and burns the stop cord, the test is inconclusive. The Commission will take no enforcement action on the basis of that test. The Commission may conduct additional testing of the fabric or article of wearing apparel, but the results of any inconclusive test shall not be averaged with results obtained from any other test.
