ASTM C518 is the Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus. Whether you manufacture polyiso boards, batt insulation, spray foams, or any number of other construction materials, it can be important to understand the thermal perfo...
ASTM C518–用熱流量計裝置測定穩態熱傳遞特性的標準試驗方法,本ASTM C518測試使用熱流量計裝置(HFM)。熱流量計由一塊冷板和一塊熱板組成,熱板上裝有熱通量感測器,用於測量熱流。待測量的材料被放置在兩個板之間,這兩個板被控制到不同的溫度,以產生從熱板到冷板的熱
该测试可用于满足绝缘材料的R值规定,如美国联邦贸易委员会的“R值规则”(10 CFR 460)。 特别注意:该方法通常可以用作ASTM C177的替代品,ASTM C177使用一种称为防护热板装置(GHP)的不同装置测定相同的性能。 Standard: ASTM C518 – Standard Test Method for Steady-State Thermal Transmission Properties by Me...
