The Standard for the Surface Flammability of Carpets and Rugs (FF 1-70) at § 1630.4(b)(1)(ii) provides that if a carpet or rug has had a fire-retardant treatment, or is made of fibers which have had a fire-retardant treatment, the sample or oversized specimens thereof selected for testing under the standard shall be washed prior to the cutting of test specimens either 10 times under the washing and drying procedure prescribed in Method 124-1996 of the American Association of Textile Chemists and Colorists or such number of times under such other washing and drying procedure as shall previously have been found to be equivalent by the Consumer Product Safety Commission. AATCC Test Method 124-1996 “Appearance of Fabrics after Repeated Home Laundering,” is found in Technical Manual of the American Association of Textile Chemists and Colorists, vol. 73, 1997, which is incorporated by reference. Copies of this document are available from the American Association of Textile Chemists and Colorists, P.O. Box 12215, Research Triangle Park, North Carolina 27709.

This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Alternatively the selected sample or oversized specimens thereof may be washed, dry-cleaned, or shampooed 10 times, prior to the cutting of test specimens, in such manner as the manufacturer or other interested party has previously established to the satisfaction of the Consumer Product Safety Commission is normally used for that type of carpet or rug in service.

Section 1630.5 of the Standard provides that if a carpet or rug has had a fire-retardant treatment or is made of fibers which have had a fire-retardant treatment, it shall be labeled with the letter “T.”

On April 10, 1972, the Federal Trade Commission, which then had responsibility for enforcement of the Flammable Fabrics Act, announced that the use of alumina trihydrate in adhesives, foams, or latexes in carpet backings or elsewhere in the backings will be considered as a fire-retardant treatment. Therefore, the provisions of §§ 1630.4(b)(1)(ii) and 1630.5 of the Standard apply to carpets with alumina trihydrate in the backings. This interpretation continues in effect.

On May 19, 1972, the Federal Trade Commission published a notice in the Federal Register (37 FR 10104) temporarily suspending the washing requirements under FF 1-70 for carpets and rugs containing alumina trihydrate in the backing. This temporary suspension was extended a number of times. On March 28, 1973 the Federal Trade Commission proposed in the Federal Register (38 FR 8101) an alternative laundering procedure for such carpets and rugs and gave notice that the suspension of the laundering requirement was extended until the completion of the proceeding to establish an alternative laundering procedure. The suspension continues in effect.
