71.040.99 - Other standards related to analytical chemistry

This document specifies specimen preparation methods for the analysis of particles in powders using energy-dispersive spectrometers (EDS) or wavelength-dispersive spectrometers (WDS) installed on an EPMA or SEM. The preparation methods for powder particle analysis are classified by the analytical purpose and the particle size. This document applies to inorganic particles larger than 100 nm and smaller than 100 µm in diameter. It applies only to analysis of "general" powders, which means that it ...view more

ISO 22489:2016 specifies requirements for the quantification of elements in a micrometre-sized volume of a specimen identified through analysis of the X-rays generated by an electron beam using a wavelength dispersive spectrometer (WDS) fitted either to an electron probe microanalyser or to a scanning electron microscope (SEM). ISO 22489:2016 also describes the following: - the principle of the quantitative analysis; - the general coverage of this technique in terms of elements, mass fractions a...view more

ISO 14595:2014 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.

ISO 17470:2014 gives guidance for the identification of elements and the investigation of the presence of specific elements within a specific volume (on a μm3 scale) contained in a specimen, by analysing X-ray spectra obtained using wavelength dispersive X-ray spectrometers on an electron probe microanalyser or on a scanning electron microscope.

ISO 23833:2013 defines terms used in the practices of electron probe microanalysis (EPMA). It covers both general and specific concepts classified according to their hierarchy in a systematic order. ISO 23833:2013 is applicable to all standardization documents relevant to the practices of EPMA. In addition, some parts of ISO 23833:2013 are applicable to those documents relevant to the practices of related fields (SEM, AEM, EDX, etc.) for definition of those terms common to them.

ISO 22029:2012 presents a simple format for the exchange of digital spectral data that has been designated as an EMSA/MAS standard. This format is readable by both humans and computers and is suitable for transmission through various electronic networks, the phone system (with modems) or on physical computer storage devices (such as removable media). The format is not tied to any one computer, programming language or computer operating system. The adoption of a standard format would enable diffe...view more

This International Standard defines the most important quantities that characterize an energy-dispersive X-ray spectrometer consisting of a semiconductor detector, a pre-amplifier and a signal-processing unit as the essential parts. This International Standard is only applicable to spectrometers with semiconductor detectors operating on the principle of solid-state ionization. This International Standard specifies minimum requirements and how relevant instrumental performance parameters are to b...view more

ISO 22309:2011 gives guidance on the quantitative analysis at specific points or areas of a specimen using energy-dispersive spectrometry (EDS) fitted to a scanning electron microscope or an electron probe microanalyser; any expression of amount, i.e. in terms of percent (mass fraction), as large/small or major/minor amounts is deemed to be quantitative. The correct identification of all elements present in the specimen is a necessary part of quantitative analysis and is therefore considered in ...view more
