ASTM C687 Standard Practice for Determination of Thermal Resistance of Loose-Fill Building Insulation
ASTM C687测定松填建筑绝热材料热阻的标准规范
The thermal resistance, R, of an insulation is used to describe its thermal performance.
The thermal resistance of an insulation is related to the density and thickness of the insulation. It is desirable to obtain test data on thermal resistances at thicknesses and densities related to the end uses of the product.
In normal use, the thickness of these
