CAN/CSA-A82.1-M87 (R2003)
Burned Clay Brick (Solid Masonry Units Made From Clay or Shale)
Product Details
Preface
This is the second edition of CSA Standard A82.1-M (now CAN/CSA-A82.1-M), Burned Clay Brick (Solid Masonry Units Made from Clay or Shale). It supersedes the previous edition published in 1977 and the imperial edition also published in 1977. It is written in SI (metric) units.
The first CSA Standard on building brick was published in 1935 under the designation A36, Standard Dimensions for Building Brick. In 1944, the Standard was revised and redesignated as the A82 Series (.1 to .6) on Brick and Hollow Tile; Part 1 was entitled Building Brick (Made from Clay of Shale). The complete series was revised in 1954 and a new Standard for facing brick was included.
This second (metric) edition is technically identical to ASTM Standard C216-1986, Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale), and better reflects the current state of the art of the clay brick manufacturing process indicated by the important changes made to Clause 5.1, Durability.
The SI metric units are a soft conversion of the yard/pound units, so that values shown are interchangeable.
The availability of environmental information allowing the production of Weathering Index Map of Canada (Figure I) is another major change to this Standard.
This Standard was prepared by the Technical Committee on Brick and Hollow Tile under the jurisdiction of the Standards Steering Committee on Masonry and was formally approved by these Committees. It has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
1.1
This Standard covers burned clay brick intended for use in masonry or in structural facing components of structures, or both.
1.2
The brick are prismatic units available in a variety of sizes, textures, colours, and shapes. This Standard is not intended to provide requirements for paving brick specified in ASTM Standard C902.
1.3
Brick are manufactured from clay, shale, or mixtures thereof, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop a fired bond between the particulate constituents to provide the strength and durability requirements of this Standard.
1.4
Brick may be shaped during manufacture by moulding, pressing, or extrusion, and the shaping method may be used to describe the brick.
1.5
Three types of brick in each of two grades are covered.
1.6
The metric values used in this Standard are based on the International System of Units (SI). The metric units are a soft conversion of the imperial units, and thus both are interchangeable and valid.
