1.1 This test method covers the evaluation of materials’ thermal resistance to heat transfer when exposed to a molten substance pour.
1.1.1 This test method was validated using molten substances of aluminum, brass, and iron. The test shall be permitted to be adapted for use with other substances.
1.2 This test method is applicable to materials from which finished primary protective apparel articles are made.
1.3 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.
1.4 Use this test method to measure and describe the properties of materials, products, or assemblies in response to molten substance pour under controlled laboratory conditions and shall not be used to describe or appraise the thermal hazard or fire risk of materials, products, or assemblies under actual conditions. However, it is acceptable to use results of this test as elements of a thermal risk assessment which takes into account all the factors that are pertinent to an assessment of the thermal hazard of a particular end use.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 8.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
