16 CFR Part 1631——Standard for the Surface Flammability of Small Carpets and Rugs

Scope of Application and Product Definitions of the Regulations:

Definition of“small area rugs and mats.”

Dimensions Standard:None of the sides shall exceed 6 feet(approximately 1.83 meters)in length,and the total surface area shall not exceed 24 square feet(approximately 2.23 square meters).Applicable Objects:All types of small carpets and mats,regardless of their manufacturing method,fiber composition(natural or synthetic),or structure,as long as they are used as floor coverings and are exposed to traffic areas in homes,offices,or other settings.

Products covered:mats that meet the above definition of size,hides with natural or synthetic fibers,and bathroom slip mats(bath mats typically fall under the definition of“small carpets”).

Products Not Applicable:

Elastic floor coverings,such as oilcloth,asphalt bricks,and vinyl floor tiles.

These guidelines apply only to carpets and mats used outdoors.

Unique items(such as antiques,Oriental rugs,and animal hides)may be excluded from testing under the conditions specified by the CPSC.

Core testing method:Pill Test The core of this standard is a simple yet rigorous testing method used to assess the flammability resistance of a carpet’s surface to small ignition sources.

Special provisions for non-conforming products:

This is the primary distinction between Parts 1631 and 1630.

According to 16 CFR§1631.5(a),small carpets and mats that do not meet the acceptance criteria of Part 1631 may still be manufactured,imported,or sold in the United States,provided that one strict condition is met:the product must be permanently marked with the following warning statement:

Flammable(does not meet US Department of Commerce standard FF 2-70):Do not use near open flames.)

Please note:Large carpets(covered by Part 1630)do not have similar exemptions or labeling provisions,and must comply fully with the standards in order to be sold.

Common high-risk product categories:

The CPSC notes that the following types,when unprocessed,typically fail the tests outlined in Part 1631:

Long-staple/puffed area rugs.

Rugs featuring a polyurethane foam layer for cushioning purposes.
