Opposite sides of the sheet shall not vary in length by more than 132 in./ft. (2.6 mm/m).7.7 Edge Straightness ToleranceThe sheet edges shall be straight within 132 in./f
33、t. (2.6 mm/m) of length or width.8. Workmanship, Finish, and Appearance8.1 WorkmanshipSheets shall have a commercially uniformly smooth surface on one side, and they shall be free of majordefects that will impair appearance, erection, use, or serviceability.8.2 FinishThe surface of the sheet to be e
34、xposed shall be smooth, granular, or otherwise textured.8.3 AppearanceThe surface of the sheet shall be the natural color of the product or may be colored by the addition of mineralpigments, chemical impregnation, pigmented coating, veneer, or embedded mineral granules.9. Inspection and Acceptance9.

The inspector representing the purchaser shall haveauthorized access to the carriers being loaded for shipment to the purchaser. The purchaser shall be afforded all reasonable andavailable facilities at the point of shipment fo

37、 of the requirements of this specification shall constitute grounds for nonacceptance.10. Product Marking10.1 IdentificationProduct marking shall include a trademark or other means of identification that ensures that themanufacturer and product category can be identified. The method of marking shall
38、 be stated in the manufacturers catalog.11. Packaging and Storage11.1 Commercial PackagingFlat sheets shall be packaged so as to ensure acceptance by common carrier. There is no standardpackage. The material is usually shipped in bulk, but it may be crated when so specified by the purchaser.11.2 Sto
39、rageFlat sheets should be piled on sufficient firm supports that will keep the sheets level and flat. The sheets shouldbe piled with the edges square and flush and covered to provide protection from the weather until used.TABLE 2 Thickness RequirementsNominal Thickness,in. (mm)Tolerance,in. (mm)18 t
