Standard Specification for Cellular Glass Thermal Insulation
2022
6
ASTM Vol.04.06 (2022)
This specification covers the composition, sizes, dimensions, and physical properties of cellular glass thermal insulation intended for use on commercial or industrial systems with operating temperatures between −450 and 800°F (−268 and 427°C). It is possible that special fabrication or techniques for pipe insulation, or both, will be required for application in the temperature range from 250 to 800°F (121 to 427°C). Contact the manufacturer for recommendations regarding fabrication and application procedures for use in this temperature range. For specific applications, the actual temperature limits shall be agreed upon between the manufacturer and the purchaser.
This specification does not cover cellular glass insulation used for building envelope applications. For cellular glass insulation used in building applications refer to Specification C1902.
Cellular glass insulation has the potential to exhibit stress cracks if the rate of temperature change exceeds 200°F (112°C) per hour.
