Standard Test Method for Measuring the Cooling Energy Provided by Wicking Liquid Moisture and Evaporating It from Clothing Materials Using a Sweating Hot Plate
1.1This test method covers the measurement of the cooling energy released back to the wearer's skin by a clothing material's ability to move and evaporate controlled dosages of water under controlled ambient conditions using a sweating hot plate.
1.1.1This test method establishes procedures for measuring the cooling energy during a simulated "sweating" phase and in a drying phase. Calculations are also provided to determine the drying time and how efficient the clothing material is at assisting in the evaporation of liquid water by comparing it to the maximum amount of energy that can be lost.
1.2This test method does not address all properties that affect a clothing material's ability to lose heat from the body. Consider measuring properties such as air permeability, insulation, and evaporative resistance.
1.3The values in SI units shall be regarded as standard. No other units of measurement are included in the standard.
1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
