摘要

1.1This practice establishes uniform general procedures for the development (preparation) and use of samples in the collaborative testing of methods for chemical analysis of sediments and similar materials.1.2The principles of this practice are applicable to aqueous samples with suitable technical modifications.1.3This 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.1.4This 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 ======5.1The objective of this practice is to provide guidelines for the preparation of samples for use in collaborative tests, to evaluate methods during their development, and for the evaluation of the precision and bias of proposed test methods.5.2Statements of the precision and bias are a mandatory part of ASTM test methods. Such an evaluation is necessary to provide guidance to the user as to the reliability of measurements that can be expected by its use. The statements are developed on the basis of user experience (ordinarily collaborative tests) with the test method.5.3The availability of test samples is a key requirement for collaborative evaluation of test methods. 1.1本规程为沉积物和类似材料化学分析方法的合作测试中样品的开发（制备）和使用建立了统一的通用程序。1.2本规程的原则适用于经过适当技术修改的含水样品。1.3本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。1.4本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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======5.1本规程的目的是为协作测试中使用的样品制备、方法开发过程中的评估以及拟议测试方法的精度和偏差评估提供指南。5.2精度和偏差声明是ASTM测试方法的强制性部分。这种评估对于向用户提供其使用所预期的测量可靠性的指导是必要的。这些声明是根据用户体验（通常是协作测试）和测试方法开发的。5.3测试样本的可用性是测试方法协作评估的关键要求。展开▼
