PART 1610_STANDARD FOR THE FLAMMABILITY OF CLOTHING TEXTILES--Table 
of Contents
 
                     Subpart B_Rules and Regulations
 
Sec.  1610.32  General requirements.

    (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 Sec.  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 Sec.  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 Sec.  Sec.  
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.
