Abstract

This paper discusses the merits and deficiencies of some existing and proposed test methods for the evaluation of fabrics intended for protection against radiant heat and flame. Modifications to improve the apparatus and the procedures are suggested.

The factors investigated include (1) the means used to obtain a given radiant or convective heat flux; (2) the type, design, and construction of the heat sensor; and (3) the specimen mounting.

Standard Test Methods British Standard for Clothing for Protection Against Intense Heat for Short Periods (BS 3791), ISO Test for Evaluation of Thermal Behaviour of Materials and Materials When Exposed to a Source of Radiant Heat (ISO 6942-1981) and ASTM Test for Thermal Protective Performance of Materials for Clothing by Open-Flame Method (D 4108-82) are considered, together with the radiant heat test method proposed in the Federal Aviation Administration's Proposed Flammability Standard for Commercial Transport Flight Attendant Uniforms (FAA-RD-75-176).
