【国外标准】 Standard Specification for Travertine Dimension Stone

This specification covers the material characteristics, physical requirements, and sampling method appropriate to the selection of travertine dimension stone for general building and structural purposes. Dimension travertine shall include stone that is sawed, cut, split, or otherwise finished or shaped, and shall specifically exclude molded, cast, or otherwise artificially aggregated units composed of fragments, and also crushed and broken stone. The physical property requirements to which travertine stones shall adhere to are absorption by weight, density, compressive strength, modulus of rupture, abrasion resistance, and flexural strength.1.1 This specification covers the material characteristics, physical requirements, and sampling appropriate to the selection of travertine for general building and structural purposes. Refer to Guides C1242 and C1528 for the appropriate selection and use of travertine dimension stone.1.2 Dimension travertine shall include stone that is sawed, cut, split, or otherwise finished or shaped and shall specifically exclude molded, cast, or otherwise artificially aggregated units composed of fragments, and also crushed and broken stone.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
