ASTM WK70391

    Revision of E989 - 18 Standard Classification for Determination of Single-Number Metrics for Impact Noise

    (What is a Work Item?)

    Active Standard: E989 - 18

    Developed by Subcommittee: E33.10 | Committee E33 | Contact Staff Manager



    WK70391


    Keywords

    floors; IIC; impact noise; impact rating; tapping machine;;

    Rationale

    An error in the description of the calculation in section 5.3 of the sum of deficiencies was found that would result in all assemblies achieving a negative infinity IIC. No one is performing the calculation in this way. This ballot corrects this mistake and makes the language in 5.3 mirror the language in 5.4
