1.1 本规程涵盖混凝土砌块、相关砌块（包括从此类砌块中获得的试件或其他试样）以及用于压缩试验的砌体棱柱的加盖装置、材料和程序。 注1: 执行这些测试方法的测试实验室应根据实践进行评估 C1093 。 1.2 本标准的文本是指提供解释性材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应被视为本标准的要求。 1.3 单位-- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且不得将两个系统的值组合使用。 1.4 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制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 本规程描述了在单元和棱镜的两个支承面上提供平面的程序。本标准的目的是为压缩试验的压盖装置和棱镜提供一致和标准化的程序。 这些程序基于测试方法中包含的（或以前包含的）程序 C140/C140M 实践 C617/C617M ，和测试方法 C1314 。 注2: 使用这种方法加盖的试样在尺寸和重量上会有很大差异。适当的护理和处理可能因样本大小和重量而异。根据被封盖样品的物理特性，提供必要的护理和处理，以提供适当的封盖。

1.1 This practice covers apparatus, materials, and procedures for capping concrete masonry units, related units, including coupons or other specimens obtained from such units, and masonry prisms for compression testing. Note 1: The testing laboratory performing these test methods should be evaluated in accordance with Practice C1093 . 1.2 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.3 Units— 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. 1.4 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. 1.5 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 This practice describes procedures for providing plane surfaces on the two bearing surfaces of units and prisms. The purpose of this standard is to provide consistent and standardized procedures for capping units and prisms for compression testing. The procedures are based on those contained (or previously contained) in Test Methods C140/C140M , Practice C617/C617M , and Test Method C1314 . Note 2: Specimens capped using this practice will vary significantly in size and weight. Appropriate care and handling may differ based on specimen size and weight. Provide care and handling as needed to provide for proper capping based on the physical characteristics of the specimen being capped.
