1.1 This practice covers the confirmation of test flames for small-scale burning tests on plastic materials using the laboratory burner described in Specification D 5025. Back pressures and flow rates for methane, propane, and butane supply gases are given for specific test flames. This practice describes a procedure to confirm the heat evolution of the test flame.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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. Results, however, of the test may be used as elements of a fire-hazard assessment or a 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.
NOTE 1--There is no similar ISO standard. This practice is equivalent in technical content to, but not fully corresponding in presentation with, the confirmatory procedures of IEC/CDV 695-11-3 and IEC/CDV 695-11-4.
1.4 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.
