1.1 本规程描述了为实验室间研究生产样品所需的基本活动。 1.2 使用本指南开发的特定实验室间样品的适用性将取决于正在进行的测试。 1.3 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 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。 1.5 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 本规程的目的是为实验室间研究的样品制备提供指南，以评估新的测试方法或用于质量控制目的。 5.2 使用这些指南制备的样品可用于测试ASTM试验方法的精度和偏差。 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。这些声明是在用户体验（通常通过实验室间研究）的基础上使用测试方法开发的。 5.3 适当样品的可用性是实验室间研究的关键要求。 5.4 用于实验室间研究的样品的均匀性必须足够小，以便与正在进行的试验的方差相比，样品引起的方差较小。

1.1 This practice describes the essential activities that are required to produce samples for interlaboratory studies. 1.2 The suitability of a particular interlaboratory sample developed using this guide will depend on the tests being made. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 ====== 5.1 The objective of this practice is to provide guidelines for the preparation of samples for interlaboratory studies to evaluate new test methods or for quality control purposes. 5.2 Samples prepared using these guidelines may be used for the testing of the precision and bias mandatory for 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 through interlaboratory studies) with the test method. 5.3 The availability of appropriate samples is a key requirement for interlaboratory studies. 5.4 The homogeneity of the sample produced for interlaboratory studies must be small enough so that the variance caused by the sample is small compared to the variance of the test being performed.
