ASTM E2749-24 PDF

1.1This standard provides general principles for measuring the uniformity of the furnace exposure on specimens tested in accordance with Test Methods E119, E814, E1529, E1725, E1966, and E2336.

1.2This practice specifies the materials and the construction requirements for a standardized test specimen used to provide a mounting surface for the instrumentation that measures furnace exposure.

1.3The instrumentation records temperatures, pressure differentials, and oxygen content near the exposed surface of the test specimen.

1.4The values stated in SI units are to be regarded as the standard. The units given in parentheses are for information only.

1.5This 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.

1.6Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.7This 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.

1.8This 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.
