ASTM E2021-09<\/h3>\n

Historical Standard: Standard Test Method for Hot-Surface Ignition Temperature of Dust Layers<\/h4>\n
\n

ASTM E2021<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers a laboratory procedure to determine the hot-surface ignition temperature of dust layers, that is, measuring the minimum temperature at which a dust layer will self-heat. The test consists of a dust layer heated on a hot plate. ,<\/sup><\/p>\n

1.2 Data obtained from this test method provide a relative measure of the hot-surface ignition temperature of a dust layer.<\/p>\n

1.3 This test method should be used to measure and describe the properties of materials in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire hazard risk of materials, products, or assemblies under actual fire conditions. However, results of this test method may be used as elements of a fire risk assessment that takes into account all of the factors that are pertinent to an assessment of the fire hazard risk of a particular end use product.<\/p>\n

1.4 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 precautionary statements are given in Section 8.<\/span><\/span><\/p>\n
