    1. Scope

    1.1 This terminology describes and illustrates imperfections observed on whitewares and related products. For additional definitions of terms relating to whitewares and related products, refer to Terminology C242. To observe these defects, examination shall be performed visually, with or without the aid of a dye penetrant, as described in Test Method C949. Agreement by the manufacturer and the purchaser regarding specific techniques of observation is strongly recommended.

    1.2 This terminology does not cover every defect or imperfection possible for whitewares or related products. The standard is not intended to be an all inclusive document for ceramic imperfections. New defect types may be created as ceramic processes, materials, and technology evolve.

    1.3 Some of the imperfection photos utilize magnification for clarity in documentation. Unless otherwise noted, typical observation conditions for detection of tile imperfections/defects shall consist of current ANSI A137.1 viewing criteria for the specific defect type

    1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
