1.1 This test method is used to provide predicted human skin burn injury for balaclavas or protective head ensembles providing head protection mounted on a stationary upright instrumented head, which are then exposed in a laboratory to a simulated fire environment having controlled heat flux, flame distribution, and duration. 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 single-layer balaclavas or protective head ensembles are recorded to aid in understanding the overall performance of the balaclava or protective head ensembles 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 in which the forearms of human subjects were exposed to elevated thermal conditions. This forearm information for skin burn injury is applied uniformly to the entire head. 1.4 The measurements obtained and observations noted can only apply to the particular balacava(s) or protective head ensemble(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 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 This test method is not a fire-test-response test method. 1.7 The values stated in SI units are to be regarded as the 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. 1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be used in conducting these tests.
This new test method is needed to provide detailed measurements and burn injury predictions specific to the head, neck, and face. This standard will be used to evaluate needed for the testing of anti-flash hoods, balaclavas, face masks, helmets, and so forth. This will be used to evaluate the performance of flame/fire-resistant head gear by researchers, manufacturers, suppliers, and end users .
