    (What is a Work Item?)

    Active Standard: C1860 - 19a

    Developed by Subcommittee: C11.02 | Committee C11 | Contact Staff Manager

    Keywords

    bond strength; design wind load; design wind pressure; negative pressure; plaster; pull test; stucco; tensile bond; tensile bond strength;;

    Rationale

    As written, the test method allows for two types of sampling; random and targeted. Targeted sampling is intended for areas of suspect deficiencies. However, a user may wish to target areas of suspect adequacy in an attempt to proof load and validate the stucco. The proposed revision adds a third criteria for sampling to allow for sampling of suspect adequacy.
