【国外标准】 Standard Guide to Dimension Stone Test Specimen Sampling and Preparation

4.1 The purpose of testing dimension stone is to quantify the various material properties of the stone. The test should consistently predict performance of the stone in a specific application. Many of the test methods that have been developed are specific and attempt to approximate the anticipated behavior of the stone in the manner that is intended to be used, such as flexural strength, compressive strength, and anchor strength. Other test methods provide general information about the stone, such as absorption and density. Test data provides the designer with information required to produce rational designs and assess if the stone will perform adequately for its intended use.1.1 This guide covers sampling, selection, preparation, and conditioning of specimens that will be used to test material properties of dimension stone.1.2 This guide sets forth basic recommendations for sampling and preparation of dimension stone test specimens and provides information regarding variables that should be considered.1.3 This guide is intended to be used by architects, engineers, contractors and material suppliers who design, select, specify, install, purchase, fabricate, finish, or test natural stone products for construction applications.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 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.
