ASTM F 2371:2016

1.1 This test method uses a sweating manikin in an environmental chamber to measure the heat removal rate and cooling duration provided by a personal cooling garment worn with a base ensemble. 2 1.1.1 The use of a sweating heated manikin is essential because of the potentially large amount of heat dissipation from the body associated with evaporative cooling. 1.2 The experimental values obtained for the cooling rates and cooling duration apply only to the particular PCS and additional garments worn during the test and for the environmental conditions used. 1.2.1 It is feasible that this test method will yield unrealistically high cooling rates for ambient air circulation systems since the manikin's surface stays continuously saturated during the test and the relative humidity in the chamber is relatively low; consequently the convective and evaporative heat loss rates from the body to the environment are probably higher from the manikin than they would be from a human, particularly in environments with higher levels of humidity. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
