ASTM F1868 Standard Test Method for Thermal and Evaporative Resistance of Clothing Materials Using a Sweating Hot Plate
ASTM F1868用焊接热板测定服装材料耐热和耐蒸发的标准试验方法

ASTM F1868服装材料热阻和湿阻测试 – 适用范围

ASTM F1868本试验方法包括服装系统用织物、薄膜、涂层、泡沫和皮革及多层复合材料在稳态条件下的热阻和湿阻的测量。

Scope: 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.

ASTM F1868服装材料热阻和湿阻测试 – 测试原理

在标准的测试环境下，加热固定的铝板或铜板，让其保持固定温度，测试加热的功率。同样，铜板或铝板上面覆盖测试布料后测试相同情况的功率，根据两者的功率差和测试盘面积的大小，就可以标定样品的热阻或者湿阻。
