标准摘要
[中文适用范围]： 本文件确定了在数据表、分析证书、报告或其他出版物中报告的有关处理纳米物体以准备表面化学分析的信息。 需要这些信息来确保使用这些材料推进研究和技术所需的分析的可靠性和可重复性，并获得对潜在纳米物体环境和生物影响的适当了解。 此类信息是与样本合成、加工历史和表征相关的其他详细信息的补充，并且应成为有关材料来源以及自产生以来发生的变化的数据记录（有时被标识为出处信息）的一部分。 本文件包括内容丰富的附件，总结了与纳米物体相关的挑战，强调了材料数据记录中增加记录和报告的必要性（附件 A），并提供了从表面化学分析溶液中提取颗粒的常用方法示例（附件B）。 附件 C 中显示了一组相关样本数据的示例。 本文件没有定义确保正确进行所描述的分析测量所需的仪器或操作程序的性质。 [外文原描述]： ISO 20579-4:2018 identifies information to be reported in a datasheet, certificate of analysis, report or other publication regarding the handling of nano-objects in preparation for surface chemical analysis. This information is needed to ensure reliability and reproducibility of analyses needed to advance research and technology using these materials, and for obtaining appropriate understanding of potential nano-object environmental and biological impacts. Such information is in addition to other details associated with specimen synthesis, processing history and characterization, and should become part of the data record (sometimes identified as provenance information) regarding the source of the material and changes that have taken place since it was originated. ISO 20579-4:2018 includes informative annexes that summarize challenges associated with nano-objects that highlight the need for increased documentation and reporting in a material data record (Annex A) and provide examples of methods commonly used to extract particles from a solution for surface chemical analysis (Annex B). An example set of relevant sample data is shown in Annex C. ISO 20579-4:2018 does not define the nature of instrumentation or operating procedures needed to ensure that the analytical measurements described have been appropriately conducted.
