ASTM WK44149

    Revision of C1280 - 13 Standard Specification for Application of Exterior Gypsum Panel Products for Use as Sheathing

    (What is a Work Item?)

    Active Standard: C1280 - 13a

    Developed by Subcommittee: C11.03 | Committee C11 | Contact Staff Manager


    1. Rationale

    Development of provisions outlining procedures for preventing moisture damage to gypsum sheathing. This project grew out of withdrawn negatives on a ballot to add a minimum ground clearance requirement to the Standard. It will either be a revision to Specification C1280 or end up as a separate Standard Practice or Guide, depending on where the work leads the task group.
