ASTM WK44748

    Revision of E662 - 13d Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials

    (What is a Work Item?)

    Active Standard: E662 - 13d

    Developed by Subcommittee: E05.21 | Committee E05 | Contact Staff Manager



    WK44748

    1. Rationale

    The appendix section on Standard Reference Materials is several years old and requires an update. This ballot will revise this section with current information provided by NIST. 1.The variation in thickness should not be described as extreme as it was within 10%. 2.The information on the NIST smoke chamber and updates is inaccurate. 3.The information on precision and the usefulness of the reference material is being deleted, as a subsequent investigation by NIST revealed that differences in test results were primarily caused by poor practices in some of the participating labs.
