Standard Specification for Chemical-Resistant Masonry Units

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.
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 of three types 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 1-Types 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 2--Types I and III were formerly designated Type "H'' and "L'' respectively.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.
