1.1 This test method is used to measure the heat energy transmission through materials used in protective clothing and gloves that are exposed to a Hot Liquid Splash. This test method is applicable to woven fabrics, knit fabrics, battings, and sheet structures with permeable or impermeable coatings or laminations intended for use as clothing or gloves for protection against brief exposures to hot liquid splash hazards.
1.2 This test method is used to measure and describe the properties of materials or assemblies of materials in response to hot liquids under controlled laboratory conditions.
1.3 This test method is applicable to materials from which finished protective apparel articles are made.
1.4 This test method is limited to the hot liquid temperatures that are 40°C (72°F) below the flash point of the specific hot liquid used for testing.
Note 1—Specific thermally stable silicone liquids are available with flash points in the range of 315°C (599°F). When these thermally stable silicone liquids are used, a maximum hot liquid temperature of 260°C (500°F) is achievable. The intent of specifying the maximum temperature at 40°C (72°F) below the liquid flash point is to reduce the hot liquid fire hazard which increases significantly at temperatures equal to or above the flash point of the liquid.
1.5 This test method does not measure the flammability of materials, nor is it intended for use in evaluating materials exposed to any other thermal exposure other than hot liquid exposures.
1.6 The values as stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.
1.7 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. Specific hazard statements are given in Section 8.
