ASTM E 136 : 2022

1.1This fire-test-response test method covers the determination under specified laboratory conditions of the combustibility of building materials. Materials passing this test are typically classified as noncombustible materials.

1.2Limitations of this fire-test response test method are shown below.

1.3This test method includes two options, both of which use a furnace to expose test specimens of building materials to a temperature of 750 °C (1382 °F).

1.4This test method references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this test method.

1.5The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.6This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.

1.7Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.8This 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.

1.9This 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.
