ASTM WK43093

    Work Item: ASTM WK43093 - Revision of C1126 - 13 Standard Specification for Faced or Unfaced Rigid Cellular Phenolic Thermal Insulation

    (What is a Work Item?)

    Active Standard: C1126 - 13a

    Developed by Subcommittee: C16.22 | Committee C16 | Contact Staff Manager

    1. Rationale

    During the C 1126 task group meeting the K values of Type 3 products were discussed due to the fact that some producers will use another type of blowing agents the K value at mean Temperature of 40 F and could be slightly too low for that reason this value has to be adjusted at 50 F the K factor is slightly to high and has to be decreased. The proposed value of 0.17 Btu-in/hr-ft2-F is slightly too low. It needs to be 0.18 Btu-in/hr-ft2- and to decrease the K value at -50 F to 0.18 Btu-in/hr-ft2-F ( was 0.19 )
