1.1 本规程确定并定义了测试机构人员的职责、责任和最低技术要求，以及用于测试施工用混凝土和混凝土骨料的设备的最低技术要求。 1.2 本规程为测试机构对混凝土和混凝土骨料执行指定ASTM测试方法的能力评估提供了标准。它可以由评估机构在检测机构的检查或认证中使用，也可以由其他方使用，以确定该机构是否有资格进行指定的检测。 注1: 规格 E329 为在浇筑过程中进行混凝土检查的机构的评估提供了标准。 1.3 本规程为检验机构和认可机构提供了标准，检验机构和认证机构根据本规程为检测机构的评估提供服务。 1.4 本标准的文本引用了注释和脚注，这些注释和脚注提供了解释性材料，不应被视为本标准的要求。 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。 1.6 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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 混凝土和混凝土骨料的测试和检验是获得优质施工的重要组成部分。应谨慎选择提供这些服务的检测机构。 4.2 如果检测机构符合本规范的要求，则该机构应被视为有资格执行并报告其检测结果。检测机构服务应在注册专业工程师的技术指导下提供。 4.3 本规程确立了与检测机构的组织、人员、设施和质量体系相关的基本特征。这一做法可以通过针对特定项目的更具体的标准和要求加以补充。

1.1 This practice identifies and defines the duties, responsibilities, and minimum technical requirements of testing agency personnel and the minimum technical requirements for equipment utilized in testing concrete and concrete aggregates for use in construction. 1.2 This practice provides criteria for the evaluation of the capability of a testing agency to perform designated ASTM test methods on concrete and concrete aggregates. It can be used by an evaluation authority in the inspection or accreditation of a testing agency or by other parties to determine if the agency is qualified to conduct the specified tests. Note 1: Specification E329 provides criteria for the evaluation of agencies that perform the inspection of concrete during placement. 1.3 This practice provides criteria for Inspection Bodies and Accreditation Bodies that provide services for evaluation of testing agencies in accordance with this practice. 1.4 The text of this standard references notes and footnotes, which provide explanatory material and shall not be considered as requirements of this standard. 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 testing and inspection of concrete and concrete aggregates are important elements in obtaining quality construction. A testing agency providing these services shall be selected with care. 4.2 A testing agency shall be deemed qualified to perform and report the results of its tests if the agency meets the requirements of this practice. The testing agency services shall be provided under the technical direction of a registered professional engineer. 4.3 This practice establishes essential characteristics pertaining to the organization, personnel, facilities, and quality systems of the testing agency. This practice may be supplemented by more specific criteria and requirements for particular projects.
