1.1 This test method can be used to provide predicted human skin burn injury for single or multiple layers of materials mounted on a stationary upright instrumented test apparatus that is exposed in a laboratory to a simulated fire environment having a controlled heat flux, flame distribution, and duration. This test method can also be used to evaluate different component designs (pockets, zippers, and so forth), constructions, and fabrics to assist in final prototype designs and fabric down selections and/or layering schemes before ASTM F1930 testing. The average incident heat flux is 84 kW/m2 (2 cal/scm2), with durations up to 20 s. 1.2 The visual and physical changes to the materials are recorded to aid in understanding the overall performance and how the predicted human skin burn injury results can be interpreted. 1.3 The skin burn injury prediction is based on a limited number of experiments where the forearms of human subjects were exposed to elevated thermal conditions. This forearm information for skin burn injury is applied uniformly to the entire surface to be tested. 1.4 The measurements obtained and observations noted can only apply to the material(s) or design(s) tested using the specified heat flux, flame distribution, and duration. 1.5 This test method is used to measure and describe the response of materials, products, or designs 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 designs under actual fire conditions. 1.6 This test method is not a fire-test response test method. 1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units or other units commonly used for thermal testing. If appropriate, round the non-SI units for convenience. 1.8 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 and health practices and determine the applicability of regulatory limitations prior to use.
Laboratory scale material tests do not correlate well to full-scale garment tests. Full-scale garment tests are expensive and time consuming. This test will allow testing of materials in a realistic configuration and down selection of designs and materials before protoype or garment construction or both and full-scale garment testing. This test method can be used to predict burn injury or can be used to determine the durability of different materials/designs/constructions or both when exposed to a simulatied fire environment.
