    Revision of E313 - 10 Standard Practice for Calculating Yellowness and Whiteness Indices from Instrumentally Measured Color Coordinates

    (What is a Work Item?)

    Active Standard: E313 - 10

    Developed by Subcommittee: E12.04 | Committee E12 | Contact Staff Manager



    WK47155

    1. Rationale

    The Chair of E12.04 had received complaints that the Yellowness Index section of E313 was confusing. This was discussed at the June 2014 meeting. At the meeting it was pointed out that the withdrawn D19 does not point to E313 as its replacement. Therefore, at the June meeting of E12.04 a task group was formed consisting of Gordon Leggett, Michael Brill, and me (as chair) to make the Yellowness Index section of E313 more clear. The following two items are proposed as changes for E313-10:
