scope:

This fire test response test method² covers a laboratory determination of the flash ignition temperature and spontaneous ignition temperature of plastics using a hot-air furnace.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Caution-During the course of combustion, gases or vapors, or both, are evolved that have the potential to be hazardous to personnel.

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.

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

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. Specific precautionary statements are given in 1.3 and 1.4.

NOTE 1-This test method and ISO 871-1996 are identical in all technical details.
