1.1 This test method is used to measure the thermal insulation of materials used in protective clothing when exposed to compression and immersion in hot water with a temperature up to 212F (100C). 1.2 This test method is applicable to materials used in the construction of protective clothing, including, but not limited to: woven fabrics, knit fabrics, battings, sheet structures, coated materials, laminated materials and material composites, intended for use as clothing for protection against exposure to compression and immersion in hot water. 1.3 This test method should be used to measure and describe the properties of materials, products, or assemblies in response to compression and hot water under controlled laboratory conditions and should not be used to describe or appraise the thermal hazard or fire risk of materials, products, or assemblies under actual exposure conditions. 1.4 The values as stated in SI units are to be regarded as the standard. The values in parentheses are given for information only. 1.5 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.
Structural firefighters have received burn injuries on their knees as a result of crawling and/or kneeling in hot water. The ASTM F1060 test method determines heat resistance for a firefighter kneeling on a hot surface, but does not simulate the conditions of a firefighter kneeling or crawling in hot water. This new test method for Water Immersion Compressive Heat Resistance (WICHR) will better quantify the protection provided by knee constructions than the ASTM F1060 test method for firefighters who are kneeling or crawling in hot water. Consequently, the WICHR test method will enable development of knee reinforcement constructions that provide more effective protection for firefighters crawling or kneeling in hot water which will ultimately help to reduce firefighter knee burn injuries.
