    1. Scope

    1.1 This specification covers solid, kiln fired brick and tile made from clay, shale, or mixtures thereof, suitable for indoor and outdoor use in masonry construction subjected to chemical environments (see Terminology C1232).

    1.2 The physical and chemical properties of brick and tile differ from supplier to supplier, mainly because their composition is determined by the source of raw materials. Regardless of the differences, brick and tile are considered to be one of three types and one of two classes as follows:

    1.2.1 Type I—For use where low absorption and high acid resistance are not major factors.

    1.2.2 Type II—For use where lower absorption and higher acid resistance are required.

    1.2.3 Type III—For use where minimum absorption and maximum acid resistance are required.

    Note 1Types I, II, and III may not differ significantly in thermal shock resistance. The suitability of a given brick, for a particular application should be determined at the time of purchase by agreement between the purchaser and the supplier.
    Note 2Types I and III were formerly designated Type “H'' and “L'' respectively.

    1.2.4 Class S—For use in standard applications.

    1.2.5 Class X—For use where a higher degree of precision and lower permissible variation in size than that permitted for Class S is required.

    1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.4 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.
