What it requires (2 obligations)
This Standard applies to all types of carpets and rugs used as floor covering materials, regardless of method of fabrication and whether made of natural or synthetic fibers or films, combinations of these or substitutes for them. A specimen passes 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, and at least seven of the eight specimens must meet that criterion for the product to conform.

Fibre-neutral by construction: the scope names natural fibres, synthetic fibres, films, combinations and substitutes, so the material cannot put a floor covering outside the Standard. One-of-a-kind items such as an antique, an Oriental or a hide may be excluded under conditions established by the Commission.

A carpet or rug is within this Standard where it has one dimension greater than 1.83 m (6 ft) and a surface area greater than 2.23 m² (24 sq ft). Products such as carpet squares with one dimension less than 1.83 m and a surface area less than 2.23 m², but intended to be assembled on installation into assemblies that may exceed those figures, are INCLUDED in this definition.

Carpet squares are the trap. The tile in a manufacturer's hand is small; the assembly it is designed to become is large, and this Part follows the assembly. The companion small-carpet Standard at Part 1631 excludes them expressly and sends them here, so measuring the product as supplied reaches the wrong Part. The test method and both criteria are identical to the companion Standard: a specimen passes 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, and at least seven of eight specimens must pass. Which Part applies changes the certification, not the performance required.
Quoted from the definition of "carpet or rug" in § 1630.1, including the carpet-squares sentence.
This is a register, not advice. It records what an instrument says and when it applies. Whether it applies to a particular company, product or shipment is a question for somebody who knows that business, and the answer is frequently not what the summary above would suggest.
