1.1 本指南涵盖了用于测试尺寸石材料性能的样品的取样、选择、制备和调节。 1.2 本指南阐述了尺寸石材试样取样和制备的基本建议，并提供了应考虑的变量信息。 1.3 本指南旨在供建筑师、工程师、承包商和材料供应商使用，他们设计、选择、指定、安装、采购、制造、完成或测试用于建筑应用的天然石材产品。 1.4 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等效值；因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得组合。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 测试尺寸石材的目的是量化石材的各种材料特性。测试应始终预测石材在特定应用中的性能。已经开发的许多测试方法都是特定的，并试图以预期使用的方式近似石头的预期行为，如弯曲强度、抗压强度和锚定强度。 其他测试方法提供了石头的一般信息，如吸收和密度。测试数据为设计师提供了所需的信息，以产生合理的设计，并评估石头是否能够充分发挥其预期用途。

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. ====== Significance And Use ====== 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.
