Active Standard ASTM E2749 | Developed by Subcommittee: E05.11
Book of Standards Volume: 04.07
Significance and Use
This practice describes a procedure to gather data intended to measure the uniformity of exposure conditions upon test specimens for the fire test methods described in Test Methods E119, E814, E1529, E1725, E1966 and E2336. The collected data from furnaces are intended to form a basis for performance requirements for the furnaces described in the referenced standards.
This practice does not include requirements for furnace performance.
In this procedure, the standardized test specimen is subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this procedure to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire-test-exposure conditions described in this procedure.
The attention of all persons connected with the conduct of this practice is drawn to the fact that fire testing is hazardous and that there is a possibility that harmful smoke and gases are developed during the test. There is also a possibility that mechanical and operational hazards develop during the construction of the test specimen and the disposal of the test residues. An assessment of all potential hazards and risks to health shall be made and safety precautions shall be identified and provided. Written safety instructions shall be issued. Appropriate training shall be provided to relevant personnel. Laboratory personnel shall ensure that they follow written safety instructions at all times.
1.2 This 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.
1.3 The instrumentation records temperatures, pressure differentials and oxygen content near the surface of the test specimen.
1.4 The values stated in SI units are to be regarded as the standard. The units given in parentheses are for information only.
1.5 This 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.
1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.7 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.
