1、Designation: C56 12C56 13Standard Specification forStructural Clay Nonloadbearing Tile1This standard is issued under the fixed designation C56; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision.Anumber in pa
2、rentheses indicates the year of last reapproval.Asuperscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers structural clay nonloadbearing tile
3、(partition, fireproofing, and furring).1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of tile extractedfrom masonry structures for determining conformance or non-conformance to the property requirements (Section 45) of thisstandard
4、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 subjectedto a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particul
5、ateconstituents to provide the strength and durability requirements of this specification. (See firing and fired bond in TerminologyC1232.)1.4 Fireproofing tile intended for use in load-bearing masonry shall conform to Specification C34.1.5 Tile intended for use in fireproofing structural members sh
6、all be of such sizes and shapes that they can be erected to covercompletely the exposed surfaces of the members.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 considere
7、d as requirements of this specification.1.7 The values stated in inch-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.1 This specification is under the jurisdict

Classification4.1 One grade of tile is covered, designated Grade NB.4.2 If tile having a particular color (Note 1), texture, or finish are desired, these features shall be specified separat
13、ely by thepurchaser.NOTE 1Color of tile varies with the type of clay used and degree of firing; hence, it cannot be taken as indicative of classification until after it hasbeen related to absorption by actual tests.5. Physical Properties5.1 Structural clay nonloadbearing tile shall conform to the fo
14、llowing requirements for absorption:Absorption by 1-h Boiling,A %Grade Individual MaximumNB 28AThe range in percentage absorption for tile delivered to any one job shall be not more than 12.6. Dimensions and Permissible Variations6.1 No overall dimension shall vary more than 3 % over or under the sp
15、ecified dimension for any form or size of tile. See Note2.NOTE 2Purchasers and designers should ascertain the type and size of tile, modular or non-modular, available in the locality under consideration andshould specify accordingly, stating the size and type represented by the available tile.Modula
16、r sizes are designated by the specified nominal dimensions which are equal to the actual manufactured dimensions plus the thickness of onemortar joint, not to exceed 12 in. (12.7 mm). For example, if the modular, specified, or nominal dimensions of a unit are 4 by 8 by 12 in. (102 by 203by 305 mm) t
17、he actual manufactured dimensions may be 312 by 712 by 1112 in. (114.7 by 215.7 by 317.7 mm).7. Finish and Appearance7.1 All tile shall be reasonably free of laminations and of cracks, blisters, surface roughness, and other defects that wouldinterfere with the proper setting of the tile or impair th
18、e strength or permanence of the construction.7.2 The finish of the outer face or faces of tile shall be plaster-base finish or exposed wall finish as specified in the invitationfor bids.7.3 Surfaces of tile for plaster-base finish shall be smooth, scored, combed, or roughened. When smooth, the tile
19、shall be freeof glaze and the absorption shall be not less than 5 % nor more than 25 %. When scored, each groove shall be not less than 116in. (1.6 mm) nor more than 116 in. (6.4 mm) in depth, and not more than 1 in. (25.4 mm) in width. The area covered by the groovesshall not exceed 50 % of the are
20、a of the scored faces. When combed, the tile shall be scratched or scarified prior to firing bymechanical means which shall make scratches or scarifications on the surface of the tile not less than 116 in. nor more than 18 in.(3.2 mm) in depth, and not more than 14 in. apart. When roughened, the die
21、 skin on the face of the tile shall be entirely brokenby mechanical means, such as wire cutting or wire brushing. (The die skin may be observed within the cells of the tile.)7.4 Surfaces of tile with exposed finish shall be smooth, combed, or roughened. Combed or roughened tile surfaces shallconform
22、 to the requirements for these finishes given in 6.37.3.8. Number of Cells and Weights8.1 Partition and split furring tile shall conform to the requirements prescribed in Table 1 for total number of cells, number ofcells in the direction of wall thickness, and weight per unit area.2 For referencedAS

24、 nonloadbearing tile shall be waived if the overallthickness of the shells, measured between the inner and extreme outer surfaces of scored tile, is not less than 58 in. (15.9 mm) andthe mean shell thickness of unscored tile is not less than 12 in. (12.7 mm). Thickness of webs shall be not less than
25、 12 in. (12.7mm).9. Sampling and Testing9.1 The purchaser or his authorized representative shall be accorded proper facilities for sampling and inspection of units bothat the place of manufacture and at the site of the work.At least 10 days from the time of sampling should be allowed for completiono
26、f the tests.9.2 Tile shall be sampled and tested in accordance with Test Methods C67.NOTE 3Unless otherwise specified in the purchase order, the cost of tests is typically borne as follows: If the results of the tests show that the tiledo not conform to the requirements of this specification, the co
27、st is typically borne by the seller. If the results of the test show that the tile do conformto the requirements of this specification, the cost is typically borne by the purchaser.10. Rejection10.1 In case the shipment fails to conform to the requirements, the manufacturer is permitted to sort it,
28、and new specimens shallbe selected by the purchaser from the retained lot and tested at the expense of the manufacturer. In case the second set of specimensfails to meet the requirements, the entire lot shall be rejected.11. Keywords11.1 clay; masonry construction; nonloadbearing tile; physical prop
