anceThermal resistance measurements, taken at scheduled times, are an integral part of the test method.
Interpretation of DataProcedures are included to properly apply the theory and techniques to achieve the desired goals.
1. Scope
1.1 This test method covers a procedure for predicting the long-term thermal resistance (LTTR) of unfaced or permeably faced rigid gas-filled closed-cell foam insulations by reducing the specimen thickness to accelerate aging under controlled laboratory conditions (1
