Title
Standard Test Method for Radiant Heat Resistance of Flame Resistant Clothing Materials with Continuous Heating
ASTM International
Publication Date:
Feb 1, 2008
Scope:
This test method rates the non-steady state thermal resistance
or insulating characteristics of flame resistant clothing materials
subjected to a continuous, standardized radiant heat exposure.
This test method is not applicable to clothing materials that
are not flame resistant.
NOTE 1—The determination of a clothing material's flame
resistance shall be made prior to testing and done in accordance
with the applicable performance standard, specification standard,
or both, for the clothing material's end-use.
This test method does not predict skin burn injury from the
standardized radiant heat exposure as it does not account for the
thermal energy contained in the test specimen after the exposure
has ceased.
NOTE 2—See Appendix X4 for additional information regarding this
test method and predicted skin burn injury.
This test method is used to measure and describe the response of
materials, products, or assemblies to heat 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.
The values stated in SI units are to be regarded as standard.
The values given in brackets are mathematical conversions to
inch-pound or other units that are commonly used for thermal
testing.
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.
