适用范围

This test method is used to evaluate the heat resistance of materials, clothing and equipment when exposed to combination of convective heat and radiant heat in a hot air circulating oven.

If specified, this test method is used for the measurement of material shrinkage following a convective heat exposure in a hot air circulating oven.

This test method is not intended to simulate the actual exposure of material, clothing or equipment in high heat conditions such as a fire environment.

1.1 This test method covers quantitative measurements and subjective observations that characterize the performance for evaluating the heat resistance of materials, protective clothing and equipment when exposed in a hot air circulating oven.

1.2 This test method is intended to evaluate physical changes in materials, protective clothing and equipment at a specified heat exposure.

1.2.1 The specified heat exposure in the hot air circulating oven is a combination of convective heat and radiant heat.

1.3 Materials, protective clothing and equipment are evaluated for visible changes or subjected to a material property measurement following a specified heat exposure.

1.4 This test method enables the quantitative measurement of shrinkage that occurs as a result of a specified heat exposure in a hot air circulating oven.

1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to other units that are commonly used for thermal testing.

1.6 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.

Note 18212;Flame resistant and heat resistant materials are described in a range of different standards and meet a range of different requirements. For materials tested in accordance with this test method, the applicable standard shall be used to establish preconditioning, conditioning and testing conditions and requirements.
