1、Designation: C 479 04 (Reapproved 2008)Standard 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 nu

2、mber in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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, cul

3、verts, abutments, structures, or appurtenances.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2. Referenced Documents2.1 ASTM Standa

Classification4.1 Liner plates manufactured in accordance with this speci-fication shall be known as curved

5、 liner plates or flat linerplates.5. Materials and Manufacture5.1 Liner plates shall be manufactured 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, fre

6、e of objection-able defects, and conform to this specification.6. Physical and Chemical Requirements6.1 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 perfor

7、med onlywhen specified.6.2.2 Liner plates shall be acceptable if the acid-solublematter does not 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 t

8、he back of the plate (see Note 1). When five tenonribs are used, the outer fin of the exterior tenons 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

9、the same thickness, length, andwidth as standard liner plates.7.1.2 Tenon ribs shall be of trapezoidal 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, wi

10、th thesmaller base dimension to be58 618 in. (16 6 3.2 mm). Thesmaller base of the trapezoid shall 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

11、 lengths of 6in. (150 mm), 9 in. (230 mm), 12 in. (305 mm), 18 in. (460mm), or 24 in. (610 mm), 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 fl

12、at liner plates shall be 9 618 in. (2306 3.2 mm).7.4 ThicknessLiner plates, both flat and curved, 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).1This specification is

15、Box C700, West Conshohocken, PA 19428-2959, United States.7.5 DesignLiner plates are designed to be used in thenumbers and with radii corresponding to inside diameters asdesignated in Table 1.8. Workmanship, Finish, and Appearance8.1 Liner plates shall be uniformly vitrified throughout theirthicknes

16、s and have a homogeneous structural texture. Theyshall be free of chips that are more than14 by34 in. (6.4 by19 mm) in surface dimension or that have a depth greater than1164 in. (4.4 mm). They shall be free of well-defined cracks andshall have no blister with a dimension exceeding12 in. (13mm) and

17、no blister shall project more than18 in. (3.2 mm)above the surface of the liner plate. The edges 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

18、%of the largest dimension of the face.9. Test Methods9.1 Perform tests in accordance with Test 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 str

19、aightlength-wise opening to ensure compliance of shape, withregard to transverse or longitudinal 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 appropr

20、iatenumber of retest specimens all meet the specified requirements.11.
