ASTM WK43842

    Revision of C373 - 88(2006) Standard Test Method for Water Absorption, Bulk Density, Apparent Porosity, and Apparent Specific Gravity of Fired Whiteware Products

    (What is a Work Item?)

    Active Standard: C373 - 14

    Developed by Subcommittee: C21.03 | Committee C21 | Contact Staff Manager



    WK43842

    1. Rationale

    The proposed revisions are being balloted based on procedural ambiguities which have been identified by many Committee members. Clarification of these ambiguities is necessary to improve the repeatability and reproducibility of the standard. Additionally, this standard, which is used every day by the ceramic tile industry as the basis for evaluating and classifying tiles, is in need of alternative procedural parameters which are consistent with the way tiles are actually tested. The balloted revisions include the following: Alternative specimen shape, size, and preparation requirements when testing ceramic tile Improved description of testing equipment Clarification of water type and volume Clarification of boiling parameters Improved explanation of blotting and weighing procedures These changes have been discussed, researched extensively, and agreed upon by industry members over the past year, and we feel strongly that their approval would result in a more accurate and widely applicable standard.
