While both cover flammability testing of consumer textile fabrics, the test method of ASTM D1230-17 is not identical to Flammability of Clothing Textiles. This test method measures and describes 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 risk assessment of the materials, products, or assemblies under actual fire conditions.
The 16 CFR Part 1610 regulation includes a test in which a sample specimen, cut from the textile, is inserted into a frame and held in a special apparatus as it is exposed to a standard flame under specified conditions. Consumer Product Safety Commission regulations require that clothing fabrics introduced into commerce meet the requirements of the CFR.
Similarly, the test method in ASTM D1230-17 involves inserting a specimen into a frame, drying it in an oven and placing it into a desiccator before testing. This framed specimen is held in the flammability tester at a 45-degree angle, and a standardized flame is applied to the surface near the lower end. The time required for the flame to travel up the fabric at a specified distance is recorded. the test machine you can use to perform is 45 degree flammability tester.
that testing establishes three classes of textiles: Class 1, Class 2, and Class 3. These are ordered in increasing flammability, with Class 3 textiles being considered unsuitable for apparel. Since Federal regulations require apparel fabrics to meet the criteria of 16 CFR Part 1610, the ASTM D1230-17 test method cannot be recommended for acceptance testing of commercial shipments.
However, it is useful because it provides a method to test general non-regulated textile fabrics. Obviously, the provisions within this standard are important for commercial purposes, as they can assure safety in apparel sold to consumers, but knowledge of the ASTM D1230 name can be beneficial for consumers as well. Through awareness of standards and regulations, people can make safe choices with certain types of apparel.
