This test method for the determination of the flammability of blankets is considered satisfactory for acceptance testing of commercial shipments of blankets since this test method has been used extensively in the trade for acceptance testing.

This test method is used to evaluate electric blanket fabric, but tests should be performed on the fabric itself without the resistance heating wires inserted.

All fabrics made of natural or regenerated cellulose, as well as many made from other natural or synthetic fibers, are combustible. Some combustible fabrics when used for blankets are potentially dangerous to the user because of the ease of ignition, rapidity, and intensity of burning. The first characteristic can be judged with the aid of the flammability tester.

1.1 This test method provides a means to identify blanket fabrics which ignite easily and propagate flame across the surface.

1.2 This test method specifies the procedures described in the “Voluntary Blanket Flammability Standard” which has been used by the blanket industry in the United States since 1972.

1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.

Note 1—This test method is not identical to 16 CFR Part 1610, Flammability of Clothing Textiles. Consumer Product Safety Commission regulations require that fabrics introduced into commerce meet the requirements of 16 CFR Part 1610.

1.4 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
