This is the second edition of CSA A82, Fired masonry brick made from clay or shale. It supersedes the previous edition published in 2006. This Standard's technical content is similar to that of ASTM C67, Standard Test Methods for Sampling and Testing Brick and Structural Clay Tile; ASTM C216, Standard Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale); and ASTM C652, Standard Specification for Hollow Brick (Hollow Masonry Units Made from Clay or Shale). Where a number of samples are indicated in the Standard, this constitutes the minimum number required for the purpose specified.
The first CSA standard on building brick was published in 1935 under the designation CSA A36, Standard dimensions for building brick. In 1944, the standard was revised and redesignated as the CSA A82 Series (CSA A82.1 to CSA A82.6) on brick and hollow tile. The complete series was revised in 1954 and a new standard for facing brick was included. In 2006, the three remaining standards [CSA A82.1 Burned clay brick (solid masonry units made from clay or shale); CSA A82.2 Methods of sampling and testing brick ; and CSA A82.8 Hollow clay brick] were replaced with the consolidated CSA A82 Fired masonry brick made from clay or shale.
1.1 This Standard applies to brick made from fired clay or shale that are intended for use as structural and/or facing components in masonry. It includes testing and other requirements pertaining to freeze-thaw durability, finish, texture, colour, compressive strength, absorption, efflorescence, size, warpage, and outof-square. Note: See Annex A for information on brick availability, durability of finish, and ordering. Annex B provides commentary on brick properties, durability, and use. For masonry of fired brick designed in accordance with CSA S304, see Clause B.8.3. 1.2 This Standard does not specify requirements for clay paving brick, thin brick, or glazed brick. 1.3 This Standard specifies requirements for two grades of brick - EG (Exterior Grade) and IG (Interior Grade), and three types of brick - Type S, Type X, and Type A. Brick may be solid, cored, or hollow. 1.4 Although this Standard provides test methods for initial rate of absorption (Clause 16) and efflorescence (Clause 17), these characteristics are not used as qualifying conditions for determining compliance of brick with this Standard. 1.5 Testing of brick removed from in-situ masonry construction is not within the scope of this Standard. 1.6 In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
