ASTM F2371-05

1.1 This test method covers the measurement of heat removal rate from a sweating heated manikin as well as the duration of cooling provided by a cooling garment, in order to assess the effectiveness of PCS.

1.1.1 This test method requires the use of a sweating heated manikin. The sweating capability is essential, to take into account the potentially large fraction of heat dissipation 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 clothing ensemble (standard outer garment, outer garment integrated to the PCS, or any other outer garment, as appropriate) as tested, and for the specified environmental conditions.

1.3 The values stated in this standard shall be SI units.

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.
