ASTM F1868-09

Historical Standard: Standard Test Method for Thermal and Evaporative Resistance of Clothing Materials Using a Sweating Hot Plate

ASTM F1868

Scope

1.1 This test method covers the measurement of the thermal resistance and the evaporative resistance, under steady-state conditions, of fabrics, films, coatings, foams, and leathers, including multi-layer assemblies, for use in clothing systems.

1.2 The range of this measurement technique for intrinsic thermal resistance is from 0.002 to 0.5 K·m2/W and for intrinsic evaporative resistance is from 0.0 to 1.0 kPa·m2/W.

1.3 The values in SI units shall be regarded as 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
