1、Designation: C 56 05Standard Specification forStructural Clay Nonloadbearing Tile1This standard is issued under the fixed designation C 56; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in pare

2、ntheses indicates the year of last reapproval. A superscriptepsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.Note Changes were made throughout and the year date changed on April 14, 2005.1

3、. Scope*1.1 This specification covers structural clay nonloadbearingtile (partition, fireproofing, and furring). One grade of tile iscovered, designated Grade NB.1.2 The property requirements of this standard apply at thetime of purchase. The use of results from testing of tileextracted from masonry

4、 structures for determining conform-ance or non-conformance to the property requirements (Section3) of this standard is beyond the scope of this standard.1.3 Tile covered by this standard are manufactured fromclay, shale, or similar naturally occurring substances andsubjected to a heat treatment at

5、elevated temperatures (firing).The heat treatment must develop sufficient fired bond betweenthe particulate constituents to provide the strength and dura-bility requirements of this specification. (See firing and firedbond in Terminology C43.)1.4 Fireproofing tile intended for use in load-bearing ma

6、-sonry shall conform to Specification C34.1.5 If tile having a particular color (Note 1), texture, orfinish are desired, these features shall be specified separatelyby the purchaser.NOTE 1Color of tile varies with the type of clay used and degree ofburning; hence, it cannot be taken as indicative of

7、 classification until afterit has been related to absorption by actual tests.1.6 The text of this specification references notes andfootnotes that provide explanatory material.

SeeNote 2.NOTE 2Purchasers and designers should ascertain the type and size oftile, modular or non-modular, available in the locality under considerationand should specify accordingly, stating the size and type represented bythe available tile.Modular

13、sizes are designated by the specified nominal dimensionswhich are equal to the actual manufactured dimensions plus the thicknessof one mortar joint, not to exceed12 in. (12.7 mm) (see Section 6.)

Workmanship, Finish, and Appearance7.1 The finish of the outer face or faces of tile shall beplaster-base finish or exposed wall finish as specified in t

18、heinvitation for bids.7.2 Surfaces of tile for plaster-base finish shall be smooth,scored, combed, or roughened. When smooth, the tile shall befree of glaze and the absorption shall be not less than 5 % normore than 25 %. When scored, each groove shall be not lessthan116 in. (1.6 mm) nor more than11

19、6 in. (6.4 mm) in depth,and not more than 1 in. (25.4 mm) in width. The area coveredby the grooves shall not exceed 50 % of the area of the scoredfaces. When combed, the tile shall be scratched or scarifiedprior to burning by mechanical means which shall makescratches or scarifications on the surfac

20、e of the tile not less than116 in. nor more than18 in. (3.2 mm) in depth, and not morethan14 in. apart. When roughened, the die skin on the face ofthe tile shall be entirely broken by mechanical means, such aswire cutting or wire brushing. (The die skin may be observedwithin the cells of the tile.)7

21、.3 Surfaces of tile with exposed finish shall be smooth,combed, or roughened. Combed or roughened tile surfacesshall conform to the requirements for these finishes given in7.2.8. Sampling and Test Units8.1 The purchaser or his authorized representative shall beaccorded proper facilities for sampling

22、 and inspection of unitsboth at the place of manufacture and at the site of the work. Atleast 10 days from the time of sampling should be allowed forcompletion of the tests.8.2 Tile shall be sampled and tested in accordance with TestMethods C67.9.
