度、矿物纤维质量的绝缘板条和毯子，不包括任何膜面。这些产品的表观导热系数数据通常在平均温度23.9C（75F）和热-冷板温差27.8C（50F）或22.2C（40F）下报告。
Scope
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 ei
