1.1 This test method evaluates the relative flammability of textiles and garments intended for use in children’s sleepwear. The procedures of this test method follow testing and laundering procedures used to evaluate the flammability of children’s sleepwear contained in U.S. Federal Regulations 16 CFR 1615 and 1616. 1.2 A textile used in children’s sleepwear must be tested in its original state and after 50 laundering and drying cycles to assess the flame resistance of the textile relative to its use life. 1.3 This method is identical to the method outlined in the regulations 16 CFR 1615 or 1616. The regulation includes additional information such as sampling plans, record keeping requirements, and interpretations for compliance applicable to children’s sleepwear. Please consult 16 CFR 1615 and 1616 for these operations and interpretations. 1.4 The values stated in SI units are to be regarded as the standard; inch-pound units are provided for information only. 1.5 This test method 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. 1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental health practices and determines the applicability of regulatory limitations prior to use. Specific precautionary information is found in 8.5 and 9.5.
