(Specification)Standard Specification for Structural Clay Facing Tile
Standard Specification for Structural Clay Facing Tile
ABSTRACT
This specification covers structural clay load-bearing facing tile. Structural facing tile are tile designed for use in interior and exterior unplastered walls and partitions of buildings. Two classes of structural clay facing tile are covered: standard - tile suitable for general use in exterior or interior masonry walls and partitions, and special duty - tile suitable for general use in exterior or interior masonry walls and partitions, and designed to have superior resistance to impact and moisture transmission and to support greater lateral and compressive loads than standard tile construction. Two types of structural clay facing tile are covered: type FTX - smooth-face tile suitable for general use in exposed exterior and interior masonry walls and partitions, and type FTS - smooth- or rough texture face tile suitable for general use in exposed exterior and interior masonry walls and partitions. The tile shall conform to one of the requirements for water absorption of the type specified as prescribed. The tile shall conform to the requirements for compressive strength of the class specified as prescribed. The tile shall be of the sizes and shapes specified. Requirements as to coring shall apply to multicored tile only. The compressive strength and absorption by 1-h boiling shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers structural clay load-bearing facing tile. Structural facing tile are tile designed for use in interior and exterior unplastered walls and partitions of buildings.
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 nonconformance to the property requirements (Section 6) 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 specification.
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

partitions and adapted for use where tile of moderate absorption, moderate variation in face dimensions, and medium color range
are permitted, and where minor defects in surface finish, including small handling chips, are not objectionable.
