This Standard covers structural clay load-bearing wall tile made from surface clay, shale, fire clay, or mixtures thereof. Two grades of tile are covered, as follows:
Grade LB X - Suitable for general use in masonry construction and adapted for use in masonry exposed to weathering, provided they are burned to the normal maturity of the clay. They may also be considered suitable for the direct application of stucco;
Grade LB - Suitable for general use in masonry where not exposed to frost action, or for use in exposed masonry where protected with a facing of 75 mm or more of stone, brick, terra cotta, or other masonry.
Note: If tile having a particular colour, texture, or finish is desired, these features should be specified separately by the purchaser (see Appendix A, Note 1).
This Standard covers structural clay non-load-bearing tile (partition, fireproofing, and furring) made from surface clay, shale, fire clay, or mixtures thereof. One grade of tile is covered and is designated Grade NB.
Fireproofing tile intended for use in load-bearing masonry shall conform to CSA Standard A82.4-M, Structural Clay Load- Bearing Wall Tile.
Note: If tile having a particular colour*, texture, or finish is desired, these features should be specified separately by the purchaser. (*Colour of tile varies with the type of clay used and degree of burning; hence, it cannot be taken as indicative of classification until after it has been related to absorption by actual tests.)
This Standard covers procedures for the sampling and testing of structural clay tile for mass determinations, compressive strength, absorption, and freezing and thawing.
