ISO 14595:2003旨在促进电子探针微量分析（EPMA）中分析数据的国际交换和兼容性。它为评价和选择标准物质（RMs）提供了指导，对RMs的异质性和稳定性进行了评估，并为生产EPMA认证标准物质的RMs化学成分的测定提供了建议。 ISO 14595:2003给出了用于电子探针微量分析（EPMA）的单相认证标准物质（CRM）的建议。它还提供了使用标准物质对平面抛光试样进行微量分析的指南。它不包括有机或生物材料。

ISO 14595:2003 has been developed to facilitate international exchange and compatibility of analysis data in electron probe microanalysis (EPMA). It gives guidance on evaluating and selecting reference materials (RMs), on evaluating the extent of heterogeneity and stability of RMs and it gives recommendations for the determination of the chemical composition of RMs for production as EPMA certified reference materials. ISO 14595:2003 gives recommendations for single-phase certified reference materials (CRMs) used in electron probe microanalysis (EPMA). It also provides guidance on the use of CRMs for the microanalysis of flat, polished specimens. It does not cover organic or biological materials.
