ASTM WK76765

Revision of C1289-20 Standard Specification for Faced Rigid Cellular Polyisocyanurate Thermal Insulation Board


None Provided


This work item will be used to address comments from a previous ballot that moved alternate mean temperature R-values to an appendix. The ballot passed but there were several affirmative with comments that the task group agreed with. There was also a comment from a negative voter who agreed to withdraw his negative. The specific changes are 1. provide addition notes to ensure users know where to find the alternate mean temperature R-values and 2. add the mandatory R-values in the appendix for comparison.
