1.1 This is a fire-test-response test method. 1.2 This test method assesses the burning behavior of upholstered seating used in school buses by measuring specific fire-test responses when a school bus seat specimen is subjected to a specified flaming ignition source under normally ventilated conditions. 1.3 The ignition source is a gas burner. 1.4 This fire test is primarily useful to distinguish products that, when exposed to an ignition source, will become fully involved in fire from other products that will not. 1.5 Data are obtained describing the burning behavior of the seat assemblies from a specific ignition source until all burning has ceased. 1.6 This test method does not provide information on the fire performance of upholstered seating in fire conditions other than those conditions specified. 1.7 The burning behavior is visually documented by photographic or video recordings, whenever possible. 1.8 The system of units to be used in referee decisions is the SI system of units; see IEEE/ASTM SI-10 for further details. The units given in parentheses are for information only. 1.9 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but it 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. 1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be used in conducting these tests. 1.11 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.
This is similar to a standard developed by the school bus manufacturers; association. They have requested ASTM to develop this test into an open standard. This standard provides for enhanced fire safety of school buses.
