a method for measuring the protection provided by apparel fabrics in a fire environment is described. a fabric is subjected to a heat load, and the transmitted heat flux is measured. the apparatus can be adjusted to simulate a variety of fire situations: the total incident heat flux can be varied, as well as the ratio of the radiative and convective components; the heat sensor can be in contact with the fabric, or at a distance, simulating looseness of fit of various garments; resistance to ignition can be determined by exposing the heated specimen to a pilot flame; and the heat received by the fabric at which charring or melting occurs can be determined typical results on a variety of ignition resistant fabrics are shown and related to fabric construction parameters. the results are expressed in terms of time of exposure until an incipient second-degree burn is likely to occur. 11 refs
