(Specification)Standard Specification for Structural Clay Nonloadbearing Screen Tile
Standard Specification for Structural Clay Nonloadbearing Screen Tile
ABSTRACT
This specification covers the standard for unglazed, structural clay nonloadbearing screen tile. This standard, however, does not cover the use of results from testing of tile extracted from masonry structures. Specimens in this standard shall be manufactured from clay, shale or similar naturally occurring substances and shall undergo firing. Two types of tiles shall be covered in this specification: the type STX and type STA. Tiles shall adhere to physical properties such durability. All the tiles shall be reasonably free from laminations and other defects.
SCOPE
1.1 This specification covers unglazed, structural clay, nonloadbearing screen tile.
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 nonconformance to the property requirements (Section 5) 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.
