(Specification)Standard Specification for Thin Veneer Brick Units Made From Clay or Shale
Standard Specification for Thin Veneer Brick Units Made From Clay or Shale
ABSTRACT
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.
SCOPE
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 13/4 in. (44.45 mm).
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 7) of this specification is beyond the scope of this specification.
1.3 The brick are prismatic units available in a variety of sizes, textures, colors, and shapes. This specification is not intended to provide specifications for paving brick (see Specification C902).
1.4 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.)
1.5 Thin brick are shaped during manufacture by molding, pressing, or extrusion. The shaping method is a way to describe the thin brick. Thin brick may also be cut from thicker masonry units.
1.5.1 This standard and its individual requirements shall not be used to qualify or corroborate the performance of a masonry unit made from other materials, or made with other forming methods, or other means of binding the materials.
1.6 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.
1.7 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.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
