    WK70964

    1. Scope

    This test method is used to provide predicted human skin burn injury for single-layer garment materials or protective clothing ensemble materials mounted on a bench-scale stationary instrumented cylinder, which are then exposed in a laboratory to a simulated fire environment having controlled heat flux, flame distribution, and duration. The average exposure heat flux is 84 kW/m2 (2 cal/cm2s), with durations up to 20 seconds.

    Rationale

    Existing bench-scale methodologies (e.g. ASTM F2700), all of which have a single sensor, provide limited information. They provide only heat flux data through a flat fabric specimen, but ignore other physical responses like dimensional change and break-open. Large-scale tests (e.g. ASTM F1930) have limited availability and high cost of testing. They also have a larger number of non-fabric variables that may impact test results. This proposed Test Method will allow for generation of more information (from multiple sensors), while not introducing garment-level variables.

    The title and scope are in draft form and are under development within this ASTM Committee.
