ASTM C 653礦物纖維板材測試??標準名稱?

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

ASTM C653 隔熱的礦物纖維塊材和板材標準規(guī)范?

ASTM C 653礦物纖維板材測試??標準簡介?

ASTM C 653描述了作為產(chǎn)品代表的特定密度和厚度的低密度毯式絕緣材料熱阻值的計算和插值。它要求該平均密度和厚度的測量值,以及由試驗方法C 177、C 518或C 1114確定的表觀導(dǎo)熱系數(shù)值。?

本指南適用于礦物纖維材料的密度范圍約為6.4至48 kg/m3(0.4至3.0 lb/ft3)。它主要適用于低密度、礦物纖維質(zhì)量的絕緣板條和毯子,不包括任何膜面。這些產(chǎn)品的表觀導(dǎo)熱系數(shù)數(shù)據(jù)通常在平均溫度23.9°C(75°F)和熱-冷板溫差27.8°C(50°F)或22.2°C(40°F)下報告。

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).?
