Standard Test Method for Elevated Temperature and Humidity Resistance of Vapor Retarders for Insulation

Importancia y uso:

5.1 On systems operating at sub-ambient temperature, humid ambient conditions cause a vapor driving force toward the insulation. If not retarded, the driven moisture vapor is detrimental to the insulation's thermal resistance. A vapor retarder must resist degradation in order maintain its resistance to vapor passage. Degradation in this test method is induced by elevated temperature and humidity conditions.
