ASTM WK33935

    Work Item: ASTM WK33935 - Revision of C1260 - 07 Standard Test Method for Potential Alkali Reactivity of Aggregates (Mortar-Bar Method)

    (What is a Work Item?)

    Active Standard: C1260 - 07

    Developed by Subcommittee: C09.26 | Committee C09 | Contact Staff Manager



    1. Rationale

    The method needs to be brought into compliance with requirements for SI-only standards. Section 9.1 provides a statement regarding accuracty of length measurement rather than referring this aspect to C 490/C490M. There ts reported confusion around the initial temperature of the water used to soak the specimens in section 9.1 of the method.
