Historical (view previous versions of standard)
This specification covers structural clay loading-bearing wall tiles of the following grades: Grade LBX, suitable for general use in masonry construction and adapted for use in masonry exposed to weathering; and 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 stone, brick, terra cotta, or other masonry. Tile covered by this specification are manufactured from clay, shale, or similar naturally occurring substances and subjected to heat treatment at elevated temperatures (firing), which must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements. Tiles shall adhere to water absorption, compressive strength, and dimensional (nominal thickness and mass) requirements specified for individual grades.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers structural clay load-bearing wall tile.
1.2 The property requirements of this specification 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 5) of this standard is beyond the scope of this specification.
1.3 Tile covered by this specification 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 C1232.)
1.4 The text of this specification 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.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
