ASTM C56-05

Standard Specification for Structural Clay Nonloadbearing Tile

ABSTRACT
This specification covers structural clay nonloadbearing tile (partition, fireproofing, and furring). One grade of tile is covered, Grade NB. Structural clay non-load-bearing tile shall conform to the specified requirements for absorption. Tile intended for use in fireproofing structural members shall be of such sizes and shapes that they can be erected to cover completely the exposed surfaces of the members. All tile shall be reasonably free of laminations and of cracks, blisters, surface roughness, and other defects that would interfere with the proper setting of the tile or impair the strength or permanence of the construction.
SCOPE
1.1 This specification covers structural clay nonloadbearing tile (partition, fireproofing, and furring). One grade of tile is covered, designated Grade NB.
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 ) 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 Fireproofing tile intended for use in load-bearing masonry shall conform to Specification C 34.
1.5 If tile having a particular color (Note 0), texture, or finish are desired, these features shall be specified separately by the purchaser.Note 0Color 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.
1.6 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.
