1、Designation: C530 10 C530 12Standard 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 a
3、pply at the time of purchase. The use of results from testing of tile extractedfrom masonry structures for determining conformance or nonconformance to the property requirements (Section 54) of thisspecification is beyond the scope of this standard.1.3 Tile covered by this specification are manufact
4、ured 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. (S
5、ee firing and fired bond in TerminologyC1232).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 i
6、nch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.2.

GradesClassification3.1 Three grades of screen tile, based on relative durability, are covered as follows:NOTE 1Screen walls present many more exposed surfaces than other brick or tile walls, the question of durability and selection of grade may be morecritical i

For this reason, these requirements are more conservative than for brick.3.1.1 Grade SEScreen tile exhibiting a uniformly high resistance to disintegration by weathering or by freezing or thawingin the presence of moisture.3.1.2 Grade MEScreen tile exhibiting a moderate and somew
9、hat nonuniform resistance to weathering. Grade ME tile exhibitgood durability in areas of mild to moderate exposure but may not be adequate for severe exposures.3.1.3 Grade NEScreen tile for interior use (no exposure to rain or freezing).3.1.4 When the grade is not specified, the requirements for Gr

Grade ME tile may be accepted in lieu of Grade NE.3.2 When the grade is not specified, the requirements for Grade ME shall govern.Two types of screen tile, based on dimensionaltolerances, are covered as follows:3.2.1

Dimensions and Permissible Variations5.1 The dimensions of screen tile units shall be specified by the purchaser.NOTE 2Since screen tile are available i
19、n 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 ascertain local availability before specifying a particular unit size or pattern.5.2 No screen tile shall have gre
20、ater dimensional variation than that permitted in Table 2.6. Finish and Appearance6.1 All tile shall be reasonably free from laminations and from defects that impair the placement, strength, or permanence ofthe construction.6.2 Tile surfaces shall be smooth, scored, combed, or roughened as specified
21、 by the purchaser.6.3 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 of at least four representative units.NOTE 3Tile colors vary with clay type and degree of burning. Color doe

Designers are c
23、autioned 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-wall units.8. Color, Texture, and Pattern8.1 Color, texture, and pattern shall be specified by the purchaser.
