(Specification)Standard Specification for Structural Clay Load-Bearing Wall Tile
Standard Specification for Structural Clay Load-Bearing Wall Tile
SCOPE
1.1 This specification covers structural clay loading-bearing wall tile. Two grades of tile are covered, as follows:
1.1.1 Grade LBX—Suitable for general use in masonry construction and adapted for use in masonry exposed to weathering, provided they meet the durability requirements for Grade SW of Specification C 216.
1.1.2 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 3 in. (76.2 mm) or more of stone, brick, terra cotta, or other masonry.
1.1.3 If tile having a particular color, texture, or finish are desired, these features shall be specified separately by the purchaser.
Note 1—Color 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 and strength by actual tests.
1.2 The property requirements of this standard apply at the time of purchase. The use of results from testing of tile extracted from masonry structures for determining conformance or non-conformance to the property requirements (Section 3) of this standard is beyond the scope of this standard.
1.3 Tile covered by this standard 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 this specification. (See firing and fired bond in Terminology C 43.)
1.4 The text of this standard 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.
