Revision of C552-21 Standard Specification for Cellular Glass Thermal Insulation


ASTM C552 includes references to Type IV - cellular glass insulation Board fabricated from Type I Flat Block. The Type IV Board product is now covered under the new standard - ASTM C1902 Standard Specification for Cellular Glass Insulation Used in Building and Roof Applications. It was discussed and agreed in the ASTM C552 Task Group that references to Type IV Board shall be removed from the ASTM C552 standard since that material is now covered under C1902. This proposed revision is to remove the Type IV references from the ASTM C552 standard. Please note, while the entire standard is included for context, only the highlighted changes, (red and crossed out items) are being balloted.
