ASTM C653-1997(2012) Standard Guide for Determination of the Thermal Resistance of Low-Density Blanket-Type Mineral Fiber Insulation
ASTM C653-1997(2012) 低密度毡型矿物纤维隔热材料热阻测定标准指南
1. ASTM C167标准适用范围
1.1 This guide describes the calculation and interpolation of a thermal resistance value for low-density blanket-type insulation material at a particular density and thickness having been selected as representative of the product. It requires measured values of this average density and thickness, as well as apparent thermal conductivity values determined by either Test Method C177 or C518.
