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…

Glass in building — Determination of the emissivity
This document specifies a procedure for determining the emissivity at room temperature of the surfaces of glass and coated glass.
The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing according to ISO 9050[5], ISO 10291[6], ISO 10292[7],…
