17、al Barriers to Trade (TBT) Committee.16. Dimensions and Permissible Variations6.1 The dimensions of screen tile units shall be specified bythe purchaser.NOTE 2Since screen tile are available in numerous sizes and shapes,the purchaser must specify these items. All sizes and shapes are notnecessarily

18、available in all parts of the United States. Therefore, thespecifier should ascertain local availability before specifying a particularunit size or pattern.6.2 No screen tile shall have greater dimensional variationthan that permitted in Table 2.7. Finish and Appearance7.1 All tile shall be reasonab

19、ly free from laminations andfrom defects that impair the placement, strength, or perma-nence of the construction.7.2 Tile surfaces shall be smooth, scored, combed, orroughened as specified by the purchaser.7.3 Color, texture, and pattern shall be specified by thepurchaser. The texture and color rang

20、e that will be visible in thefinished wall shall conform to an approved sample of at leastfour representative units.NOTE 3Tile colors vary with clay type and degree of burning. Colordoes not indicate tile classification unless it has been related to absorptionand strength by tests.Because a multitud

21、e of individual unit patterns and wall patterns areavailable, screen-wall strength in every direction may not be related to thecompressive strength of individual units. Designers are cautioned toinvestigate each wall design thoroughly and to provide sufficient expan-sion and pressure-relieving joint

22、s to eliminate induced forces that mightcreate critical stresses in screen-wall units.8. Optional Requirements8.1 If the purchaser desires closer dimensional tolerances,restrictions on chippage or roughness, or other requirementsnot specifically contained in this specification, he must so statein a
