1、Designation: C530 12C530 13Standard Specification forStructural Clay Nonloadbearing Screen Tile1This standard is issued under the fixed designation C530; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A

2、number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers unglazed, structural clay, nonloadbearing screen tile.1.2 The property requirements of this specification ap

The use of results from testing of tile extractedfrom masonry structures for determining conformance or nonconformance to the property requirements (Section 45) of thisspecification is beyond the scope of this standard.1.3 Tile covered by this specification are manufactu

4、red from clay, shale, or similar naturally occurring substances and subjectedto a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulateconstituents to provide the strength and durability requirements of this specification. (Se

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 in

Physical Properties5.1 DurabilityScreen tile shall meet the properties prescribed in Table 1 for resistance to absorption.6. Dimensions and Permissible Variations6.1 The

17、 dimensions of screen tile units shall be specified by the purchaser.NOTE 2Since screen tile are available in numerous sizes and shapes, the purchaser must specify these items. All sizes and shapes are not necessarilyavailable in all parts of the United States. Therefore, the specifier should ascert

18、ain local availability before specifying a particular unit size or pattern.6.2 No screen tile shall have greater dimensional variation than that permitted in Table 2.7. Finish and Appearance7.1 All tile shall be reasonably free from laminations and from defects that impair the placement, strength, o

19、r permanence ofthe construction.7.2 Tile surfaces shall be smooth, scored, combed, or roughened as specified by the purchaser.7.3 Color, texture, and pattern shall be specified by the purchaser. The texture and color range that will be visible in the finishedwall shall conform to an approved sample

20、of at least four representative units.NOTE 3Tile colors vary with clay type and degree of burning. Color does not indicate tile classification unless it has been related to absorption andstrength by tests.Because a multitude of individual unit patterns and wall patterns are available, screen-wall st

21、rength in every direction may not be related to thecompressive strength of individual units. Designers are cautioned to investigate each wall design thoroughly and to provide sufficient expansion andpressure-relieving joints to eliminate induced forces that might create critical stresses in screen-w

Optional Requirements8.1 If the purchaser desires closer dimensional tolerances, restrictions on chippage or roughness, or other requirements notspecifically contained in this specification, he must so state in a supplemental specification.9.
