ASTM F1550M-94E01

1.1 This fire-test-response standard is designed for use to determine various fire-test-response characteristics, including ignitability and heat release rate, from composites of mattresses or furniture, or correctional facilities, which have been vandalized in a prescribed manner to expose the filling material, by using a bench scale oxygen consumption calorimeter.

1.2 This test method provides for measurements of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant radiant heat flux of 35 kW/m .

1.3 The apparatus used in this test method is also capable of determining heat release data at different heat fluxes.

1.4 The specimen is oriented horizontally and a spark ignition source is used.

1.5 All fire-test-response characteristics are determined using the apparatus and the procedures described in Test Method E1354.

1.6 The tests are done on bench-scale specimens combining the mattress or furniture outer layer components. Frame elements are not included.

1.7 The vandalism is simulated by causing a prescribed cut on the outer layer of the composite, deep enough to expose the filling material to the incident radiation.

1.8 The values stated in SI units are to be regarded as the standard.

1.9 This standard should be used to measure and describe the response of materials, products or assemblies to heat and flame under controlled conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire hazard or fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard or fire risk of a particular end use.

1.10 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.
