ASTM WK69716

    Revision of E1348 - 15e1 Standard Test Method for Transmittance and Color by Spectrophotometry Using Hemispherical Geometry

    (What is a Work Item?)

    Active Standard: E1348 - 15e1

    Developed by Subcommittee: E12.02 | Committee E12 | Contact Staff Manager



    WK69716


    Keywords

    color; integrating sphere; spectrophotometer; translucent; transmittance; transparent;;

    Rationale

    Changes made to address the use a spectrophotometer dedicated to Transmittance Color measurements (e.g. Instrument is not capable of Reflectance measurements). Also added a recommendation to conduct a Linearity verification test in addition to Wavelength Scale and Stray Light verification. Also changed reference to using Haze Standards for verification from should to can since ASTM D1003 makes not reference to using these standards to verify the accuracy of the standardization
