    Significance and Use

    This terminology ensures that terms peculiar to refractories are adequately defined so that other standards in which such terms are used can be understood and interpreted properly.

    This terminology is useful to those who are not conversant with the terms related to refractories. However, it is also a ready reference for those directly associated with refractories to resolve differences and ensure commonality of usage, particularly in the preparation of ASTM standards.

    Although this terminology is intended to promote uniformity in the usage of terms related to refractories, it can never be complete because new terms are constantly arising. The existence of this terminology does not preclude the use or misuse of any term in another context.

    1. Scope

    1.1 This terminology covers terms particularly related to refractories and encompasses raw materials, manufacture, finished products, applications, and testing procedures.

    1.2 When any of the definitions in this terminology are quoted or published out of context, editorially insert the limiting phrase in refractories after the dash following the term to properly limit the field of application of the term and definition.
