ASTM C335 / C335M Standard Test Method for Steady-State Heat Transfer Properties of Pipe Insulation
ASTM C335 / C335M管道隔热稳态热传导性能的试验方法标准
As determined by this test method, the pipe insulation lineal thermal resistance or conductance (and, when applicable, the thermal resistivity or conductivity) are means of comparing insulations which include the effects of the insulation and its fit upon the pipe, circumferential and longitudinal jointing, and variations in construction, but d
