ASTM E 119：Standard Test Methods for Fire Tests of Building Construction and Materials
Abstract 摘要
These test methods are intended to evaluate the duration for which the types of building elements noted in 1.1 contain a fire, retain their
structural integrity, or exhibit both properties during a predetermined test exposure.The test exposes a test specimen to a standard fire controlled to achieve specified temperatures throughout a specified time period. When required, the fire exposure is followed by the application of a specified standard fire hose stream applied in accordance with Practice E2226. The test provides a relative measure of the fire-test
response of comparable building elements under these fire exposure conditions.
The exposure is not representative of all fire conditionsbecause conditions vary with changes in the amount, nature and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. Variation from the test conditions or test specimen construction, such as size, materials, method of assembly, also affects the fire-test-response. For these reasons, evaluation of the variation is required for application to construction in the field.
