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.
