    Revision of C470 / C470M - 09 Standard Specification for Molds for Forming Concrete Test Cylinders Vertically

    (What is a Work Item?)

    Active Standard: C470 / C470M - 09

    Developed by Subcommittee: C09.61 | Committee C09 | Contact Staff Manager


    1. Rationale

    Because shipments (lots) of single-use cylinder molds vary widely in quantity from just a few cartons to a full truckload, additional guidance regarding acceptance testing is needed. The proposed change would alleviate the possibility of rejecting an entire large shipment based on the failure of a single mold.
