1、Designation: C 479 04Standard Specification forVitrified Clay Liner Plates1This standard is issued under the fixed designation C 479; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthese
2、s indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes the criteria for the accep-tance of vitrified clay liner plates used to protectively line orface pipe, culverts, abutments,
3、 structures, or appurtenances.1.2 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.2.

4、nology3.1 Definitions:Clay, fire clay, shale, and surface clay aredefined in Terminology C 43.4. Classification4.1 Liner plates manufactured in accordance with this speci-fication shall be known as curved liner plates or flat linerplates.5. Materials and Manufacture5.1 Liner plates shall be manufact
5、ured from fire clay, shale,surface clay, or a combination of these materials that, whenformed into liner plates and fired to suitable temperatures, yielda product that is strong, durable, serviceable, free of objection-able defects, and conform to this specification.6. Physical and Chemical Requirem
6、ents6.1 AbsorptionThe absorption of liner plates shall notexceed 6 %.6.2 Acid Resistance:6.2.1 This test is used to determine the resistance of linerplates to the action of acids. The test shall be performed onlywhen specified.6.2.2 Liner plates shall be acceptable if the acid-solublematter does not
7、 exceed 0.25 %.7. Dimensions and Permissible Variations7.1 Tenon Ribs:7.1.1 Liner plates shall have either three or five longitudinal,monolithic, dovetail tenon ribs uniformly and symmetricallyspaced on the back of the plate (see Note 1). When five tenonribs are used, the outer fin of the exterior t
8、enons shall beeliminated so that parallel jointing faces between abuttingplates may be achieved.NOTE 1Special liner plates are available for linings where tenon ribsare not desired. They are furnished in the same thickness, length, andwidth as standard liner plates.7.1.2 Tenon ribs shall be of trape
9、zoidal cross section tofirmly key or attach the plate into the backup material with amortising type of fastening. The ratio of the dimension of thelarger base to the smaller base shall be about 8 to 5, with thesmaller base dimension to be58 618 in. (16 6 3.2 mm). Thesmaller base of the trapezoid sha
10、ll be adjacent to the liner plate.7.2 Length:7.2.1 Length is the overall dimension of the liner plate whenmeasured in the same direction as the tenon ribs.7.2.2 Liner plates shall be available in standard lengths of 6in. (150 mm), 9 in. (230 mm), 12 in. (305 mm), 18 in. (460mm), or 24 in. (610 mm),
11、with a tolerance of + 0, 14 in./ft oflength ( + 0, 21 mm/m of length).7.3 Width:7.3.1 The width of curved liner plates shall be 914 618 in.(2356 3.2 mm) measured along the radial arc.7.3.2 The width of flat liner plates shall be 9 618 in. (2306 3.2 mm).7.4 ThicknessLiner plates, both flat and curved
12、, shall be34 6116 in. (19 6 1.6 mm) thick. Tenon ribs shall be12 in. 6116 in. (13 6 1.6 mm) thick, which provides an overallthickness, at the tenon rib, of 114 618 in. (32 6 3.2 mm).7.5 DesignLiner plates are designed to be used in thenumbers and with radii corresponding to inside diameters asdesign

Workmanship, Finish, and Appearance8.1 Liner plates shall be uniformly vitrified throughout theirthickness and have a homogeneous structural texture. Theyshall be free of chips that are more than14
16、by34 in. (6.4 by 19mm) in surface dimension or that have a depth greater than1164in. (4.4 mm). They shall be free of well-defined cracks andshall have no blister with a dimension exceeding12 in. (13mm) and no blister shall project more than18 in. (3.2 mm)above the surface of the liner plate. The edg
17、es shall be straightand the corners square to a degree that will permit smooth andadequate peripheral joints. Faces intended to beplane or facesintended to be curved shall have no distortion greater than 1 %of the largest dimension of the face.9. Test Methods9.1 Perform tests in accordance with Test
18、 Methods C 301.10. Acceptance Testing10.1 If required, 10 plates per 1000 shall be tested bypassing through a hollow gage having the maximum alloweddimensions herein specified for the plate shape, and a straightlength-wise opening to ensure compliance of shape, withregard to transverse or longitudin
19、al warp.10.2 If any of the specimens fail to meet the test require-ments, a retest of two additional specimens for each specimenfailed shall be allowed.10.3 Liner plates shall be acceptable when the appropriatenumber of retest specimens all meet the specified requirements.11.
