16 CFR PART 1631 Flammability test to small carpets and rugs- Standard Title

16 CFR 1631 (FF 2-70) STANDARDS FOR THE SURFACE FLAMMABILITY OF Small CARPETS AND RUGS

 
16 CFR PART 1631 Flammability test to small carpets and rugs - Products Scope

This Standard provides a test method to determine the surface flammability of small carpets and rugs when exposed to a standard small source of ignition under carefully prescribed draft-protected conditions. It is applicable to all types of small carpets and rugs used as floor covering materials regardless of their method of fabrication or whether they are made of natural or synthetic fibers or films, or combinations of, or substitutes for these.

Small Carpet means any type of finished product made in whole or in part of fabric or related material and intended for use or which may reasonably be expected to be used as a floor covering which is exposed to traffic in homes, offices, or other places of assembly or accommodation, and which may or may not be fastened to the floor by mechanical means such as nails, tacks, barbs, staples, adhesives, and which has no dimension greater than 1.83 m. (6 ft.) and an area not greater than 2.23 m.2 (24 sq. ft.). Products such as ‘‘Carpet Squares’’ with dimensions smaller than these but intended to be assembled, upon installation, into assemblies which may have dimensions greater than these, are excluded excluded from this definition. They are, however, included in the Standard for the surface flammability of carpets and rugs (FF 1–70) (subpart A of part 1630 of this chapter). Mats, hides with natural or synthetic fibers, and other similar products are included in this definition if they are within the defined dimensions, but resilient floor coverings such as linoleum, asphalt tile and vinyl tile are not.

 
16 CFR PART 1631 Flammability test to small carpets and rugs- General requirements

(a) Summary of test method. This method involves the exposure of each of eight conditioned, replicate specimens of a given carpet or rug to a standard igniting source in a draft-protected

environment, and measurement of the proximity of the charred portion to the edge of the hole in the prescribed flattening frame.

(b) Test criterion. A specimen passes the test if the charred portion does not extend to within 2.54 cm. (1.0 in.) of the edge of the hole in the flattening frame at any point.

(c) Acceptance criterion. At least seven of the eight specimens shall meet the test criterion in order to conform with this Standard.
