1.1 本指南涵盖了用于制备待通过火花原子发射或X射线荧光光谱分析的试样表面的各种研磨材料的评估建议。 1.2 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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。 1.3 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 在通过火花原子发射或X射线荧光光谱分析之前，用于制备试样表面的研磨材料可能会污染表面，从而产生错误的结果。本指南提供了这些污染影响的示例，以及评估研磨材料以消除或减少光谱化学分析中这些影响的建议。 4.2 本指南中给出的示例并不是可能发生的唯一污染。特别是在X射线光谱法中，应检查表面处理的所有阶段是否存在潜在的污染影响。 4.3 观察到的污染物的分析意义取决于分析员在给定成分下对特定应用的需求。

1.1 This guide covers recommendations for the evaluation of various grinding materials used to prepare the surfaces of specimens to be analyzed by spark atomic emission or X-ray fluorescence spectrometry. 1.2 This standard does not purport to address all of the safety problems, 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. 1.3 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 grinding materials used for the preparation of the surfaces of specimens prior to analysis by spark atomic emission or X-ray fluorescence spectrometry can contaminate the surface and thus produce erroneous results. This guide provides examples of the effects of these contaminations and recommendations for evaluating grinding materials to eliminate or reduce these effects in spectrochemical analysis. 4.2 The examples given in this guide are not the only contaminations that can occur. Especially in X-ray spectrometry, all phases of the surface preparation should be examined for potential contamination effects. 4.3 Analytical significance of the contaminations observed depends on the needs of the analyst for the particular application at a given composition.
