Standard Test Method for Determination of Long-Term Thermal Resistance of Closed-Cell Thermal Insula...
Scope
1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value
measured after 5-year storage in a laboratory environment and provides means for its prediction based on
an accelerated laboratory test.
1.2 This procedure, based on ASTM standard test methods ASTM C1303 and ASTM C518, can be
applied to a wide range of preformed as well as field…
