ASTM WK75944
New Test Method for Measuring Heat Transmission Through Heat Protective Clothing Materials in Flame Exposure Using a Cylindrical Specimen Holder
1. Scope
This Committee will develop standard specifications, test methods, practices, guides, terminology, and classifications for protective clothing and related personal protective equipment (PPE) designed and constructed to protect the user from potential occupational hazards. Where applicable, this committee will also develop the requirements for conformity assessment of protective clothing and related personal protective equipment. This Committee will coordinate its efforts with other ASTM Committees and outside organizations having mutual interests.
Keywords
fire; flame testing; flammability; textile; cylinder; instrumented flammability testing; thermal testing; protective clothing; thermal heat protection; thermal energy ratio; heat transfer performance value; apparel
Rationale
Heat transmission through protective clothing is primarily determined by fabric thickness and clothing air gaps. Current tests for heat transfer performance of textile materials do not capture the effects of thermal shrinkage as a result of the planar geometry of the test device. A bench top test is needed that will evaluate the contribution of materials thermal stability leading to shrinkage, air gap reduction, and increased heat transmission.
The title and scope are in draft form and are under development within this ASTM Committee.
