ASTM WK37691

    Work Item: ASTM WK37691 - Revision of C547 - 11e1 Standard Specification for Mineral Fiber Pipe Insulation

    (What is a Work Item?)

    Active Standard: C547 - 12

    Developed by Subcommittee: C16.20 | Committee C16 | Contact Staff Manager

    1. Rationale

    There is general agreement that a caveat statement is needed in the standard to emphasize that the physical properties referenced in the standard are tested under laboratory conditions and that actual in-situ performance will vary when ambient conditions are different than the test conditions. A ballot item to add a statement to the Scope generated negatives that were found persuasive. Discussion at the Task Group resulted in agreement to add a statement to Section 4 Classification to satisfy the negatives.
