ASTM C552 Standard Specification for cellular glass thermal insulation
ASTM C552 泡沫玻璃绝热材料标准规范
ASTM C552 泡沫玻璃绝热材料标准规范—适用范围
Scope:
This specification covers the composition, sizes, dimensions, and physical properties of cellular glass thermal insulation intended for use on surfaces operating at 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.
