(Specification)Standard Specification for Structural Clay Load-Bearing Wall Tile
Standard Specification for Structural Clay Load-Bearing Wall Tile
ABSTRACT
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.
SCOPE
1.1 This specification covers structural clay loading-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 4) 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.

1. 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 C216.
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 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 34) 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.)
