    Significance and Use

    5.1 This test method provides a means for readily determining if a ceramic is properly fired (matured). Penetration of any extent may negate the usefulness of the ceramic, or, arbitrarily, some degree of penetration may be acceptable for the use or commercial quality of the item being tested.

    1. Scope

    1.1 This test method covers procedures for detecting pores, cracks, or other voids that may be present in otherwise impermeable whiteware ceramics, or as porosity in underfired ware.

    Note 1: This test method was partially derived from ANSI C29.1.

    1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use
