This specification covers the material characteristics, physical requirements, and sampling method appropriate to the selection of limestone dimension stone for general building and structural purposes. Dimension limestone shall include stone that is sawed, cut, split, or otherwise finished or shaped and shall specifically exclude molded, cast, or otherwise artificially aggregated units of composed fragments, and also crushed and broken stone. The stones shall be classified into three categories (low-density, medium-density, and high-density) according to their densities in approximate ranges. The physical property requirements to which limestone shall adhere to are absorption by weight, density, compressive strength, modulus or rupture, and abrasion resistance.
1.1 This specification covers the material characteristics, physical requirements, and sampling appropriate to the selection of limestone for general building and structural purposes. Refer to Guides C1242 and C1528 for the appropriate selection and use of limestone dimension stone.
1.2 Dimension limestone shall include stone that is sawed, cut, split, or otherwise finished or shaped and shall specifically exclude molded, cast, or otherwise artificially aggregated units of composed 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.
