1.1 This test method applies to disposable and reusable woven and nonwoven fabrics used in surgical fabrics, including surgical drapes and gowns. 1.2 The purpose of this test method is to provide standard methods for testing and classifying the ignition and flame propagation characteristics, under realistic exposure conditions, of surgical drapes and gowns as well as other fabrics used in surgery. 1.3 This test method permits evaluation of the ignition and flame propagation characteristics of textile materials exposed to surgical lasers and electrical cautery devices in atmospheres ranging from ambient air to 100 percent oxygen concentration. This test method does not indicate the performance of tested materials under exposure conditions substantially different from the test conditions. 1.4 This test method is adapted from the flammability standard described in the Code of Federal Regulations (CFR) Part 1610 [1], which is administered by the U.S. Consumer Product Safety Commission, to measure and regulate the flammability characteristics of textiles and textile products for clothing use. 1.5 Modifications to the Code of Federal Regulations (CFR) Part 1610 test method for this standard include:a)The use of a surgical laser and electric cautery commonly used during surgery as realistic ignition sources in place of the gas jet flame specified in CFR Part 1610 andb)The use of oxygen enrichment in the test chamber to simulate oxygen-enriched conditions that can occur during surgery.1.6 In this test method, the beam of a surgical laser or electric cautery wire is applied along the longitudinal centerline of the surface of a 50.8-mm (2-inch) wide by 152.4-mm (6-inch) long fabric test specimen supported at an angle of 45 degrees in a test chamber. The oxygen concentration in the test chamber is varied between tests to determine the influence of oxygen enrichment on the ignition and flame propagation characteristics of the tested fabrics. 1.7 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
