ASTM C653 Standard Guide for Determination of the Thermal Resistance of Low-Density Blanket-Type Mineral Fiber Insulation

ASTM C653 隔热的矿物纤维块材和板材标准规范

 

ASTM C 653描述了作为产品代表的特定密度和厚度的低密度毯式绝缘材料热阻值的计算和插值。它要求该平均密度和厚度的测量值，以及由试验方法C 177、C 518或C 1114确定的表观导热系数值。

 

本指南适用于矿物纤维材料的密度范围约为6.4至48 kg/m3（0.4至3.0 lb/ft3）。它主要适用于低密度、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23.9°C（75°F）和热-冷板温差27.8°C（50°F）或22.2°C（40°F）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 either Test Method C 177, C 518, or C 1114.

This guide applies to a density range for mineral-fiber material of roughly 6.4 to 48 kg/m3 (0.4 to 3.0 lb/ft3). It is primarily intended to apply to low-density, mineral-fiber mass insulation batts and blankets, exclusive of any membrane facings. Apparent thermal conductivity data for these products are commonly reported at a mean temperature of 23.9°C (75°F) and a hot-to-cold plate temperature difference of 27.8°C (50°F) or 22.2°C (40°F).
