CSA Group CSA A82:14 National Standard of Canada (reaffirmed 2023) Fired masonry brick made from clay or shale

Preface

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.

This Standard was prepared by the Technical Committee on Brick and Hollow Tile, under the jurisdiction of the Strategic Steering Committee on Masonry and has been formally approved by the Technical Committee.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Notes:

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

1 Scope

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 out-of-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.
