This specification covers thin veneer brick units made from clay, shale, fire clay, sand, or mixtures thereof, and fired to incipient fusion for use in adhered or fastened veneer applications. The brick units shall be available in both Grades Interior and Exterior of the following types: Type TBS (Standard), which are for general masonry use; Type TBX (Select), which are produced with higher degree of precision; and Type TBA (Architectural), which are selected to produce characteristic architectural effects resulting from nonuniformity in size and texture of the individual units. Materials shall undergo durability, and freezing and thawing tests and should adhere to physical property requirements such as maximum water absorption, maximum saturation coefficient, maximum water loss, breakage, cracking, and weathering index. Bricks should also conform to specified characteristics as to face finish, color and texture, size and dimensions, and warpage.

1.1 This specification covers thin veneer brick units made from clay, shale, fire clay, sand, or mixtures thereof, and fired to incipient fusion for use in adhered or fastened veneer applications. Three types of thin veneer brick units in each of two grades are covered. In this specification, the term thin veneer brick shall be understood to mean clay masonry unit with a maximum thickness of 1¾ in. (44.45 mm).

Note 1—Brick intended for paving should be specified under Specification C902.

1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or nonconformance to the property requirements (Section 5) of this specification is beyond the scope of this specification.

1.3 Brick covered by this specification are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of the specification. (See “firing” and “fired bond” in Terminology C1232.)

1.4 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.

1.5 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
