1、Designation: C 499 09Standard Test Method forFacial Dimensions and Thickness of Flat, RectangularCeramic Wall and Floor Tile1This standard is issued under the fixed designation C 499; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,
2、 the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method covers
3、the determination of the facialdimensions and thickness of flat, rectangular ceramic wall andfloor tile. This test method covers tile as defined in Terminol-ogy C 242.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 major facial dimensionthe overall length or widthof the tile,
6、 including the lugs on opposite sides.3.1.2 major thicknessthe thickness of tile, including anymaximum protuberances or ridges on the back.3.1.3 minor facial dimensionthe length or width of the tileexclusive of the lugs.3.1.4 minor thicknessthe thickness of tile that does notinclude maximum protuber
7、ances or ridges.4. Significance and Use4.1 This test method provides a means of determiningwhether a lot of tile meets specifications of variations in sizeand thickness. In specifications, the nominal size always refersto the minor facial dimension and the nominal thickness of atile always refers to
8、 the major thickness.5. Apparatus5.1 A suitable measuring device such as a micrometer ordial indicator, reading in 0.001-in. (0.025-mm) divisions andaccurate to 60.001 in. (60.025 mm), shall be used. If a dialindicator is used, suitable jigs for holding the tile and theindicator shall be provided.6.
9、 Test Specimens6.1 At least ten tile specimens shall be selected at randomfrom the lot to be tested. The same specimens may be used forthe determination of facial dimensions and thickness. Brush thespecimens to remove all adhering particles of clay or sand.7. Procedure7.1 Major Facial DimensionMeasu

For tile whose lugs are not arranged opposite each other,it may be necessary to use a jig to obtain the major facialdimensions. For square tile
11、, average all four measurements andcall the result the average major dimension. For oblong tile,average the two length measurements and call the result theaverage major length of the tile; average the two widthmeasurements and call the result the average major width ofthe tile.7.2 Minor Facial Dimen
12、sionMeasure the length of the tileexclusive of the lugs to the nearest 0.001 in. (0.025 mm) in twoplaces. Follow the same procedure for measuring the widthexclusive of the lugs. Points of measurement shall be at least0.25 in. (6.4 mm) and not more than 0.50 in. (12.7 mm) fromthe corners of the tile.
13、 For tile with tapered sides, a jig isrequired to determine the minor facial dimension of such tile.For square tile, average all four measurements and call theresult the average minor dimension.
