The American Society for Testing and Materials (ASTM) has developed Test Method for Thermal Protective Performance of Materials for Clothing by Open-Flame Method (D 4108-82). A modified version of this test is utilized in the National Fire Protection Association's NFPA 1971 (1986 Edition) and the International Organization for Standardization's (ISO) Draft Proposal 9151. The influences of these modifications on measured Thermal Protective Performance (TPP) values for composite assemblies have been determined. The sample restraining technique was identified as a critical factor in influencing the results obtained. An alternative system of mounting involving pins, is described, that prevents fabric shrinkage without compression. The behavior of a series of assemblies has been investigated using the technique and the contribution of each component (outer shell, moisture barrier, and thermal liner) to the measured TPP values evaluated.
