Protective clothing against heat and flame — Part 1: Test method for complete garments — Measurement of transferred energy using an instrumented manikin

This document specifies the overall requirements, equipment and calculation methods to provide results that can be used for evaluating the performance of complete garments or protective clothing ensembles exposed to short duration flame engulfment.

This test method establishes a rating system to characterize the thermal protection provided by single-layer and multi-layer garments made of flame resistant materials. The rating is based on the measurement of heat transfer to a full-size manikin exposed to convective and radiant energy in a laboratory simulation of a fire with controlled heat flux, duration and flame distribution. The heat transfer data is summed over a prescribed time to give the total transferred energy. Transferred energy and thermal manikin protection factor (TMPF) assessment methods provide a means to quantify product performance.

The exposure heat flux is limited to a nominal level of 84 kW/m2 and durations of 3 s to 20 s dependant on the risk assessment and expectations from the thermal insulating capability of the garment.

The results obtained apply only to the particular garments or ensembles, as tested, and for the specified conditions of each test, partic
