ASTM C870 -Standard Practice for Conditioning of Thermal Insulating Materials
ASTM C870热绝缘材料调整标准规范
The conditioning prescribed in this recommended practice is designed to obtain reproducible test results on thermal insulating materials. Results of tests obtained on these materials under uncontrolled atmospheric conditions are not comparable with each other. Some of the physical properties of thermal insulating materials are influenced by relative humidity and temperature in a manner t
