This guide describes the components for an energy-dispersive X-ray fluorescence (XRF) system for materials analysis. It can be used as a reference in the apparatus section of test methods for energy-dispersive X-ray fluorescence analyses of nuclear materials.

Formerly under the jurisdiction of Committee C26 on Nuclear Fuel Cycle, this test method was withdrawn in December 2008. This standard is being withdrawn without replacement because it is outdated and no longer needed in the industry.

This guide describes typical prospective analytical X-ray fluorescence systems that may be used for qualitative and quantitative elemental analysis of materials related to the nuclear fuel cycle.

Standard methods for the determination of materials using energy-dispersive XRF⁵ usually employ apparatus with the components described in this document.

1.1 This guide describes the components for an energy-dispersive X-ray fluorescence (XRF) system for materials analysis. It can be used as a reference in the apparatus section of test methods for energy-dispersive X-ray fluorescence analyses of nuclear materials.

1.2 The components recommended include X-ray detectors, signal processing electronics, data acquisition and analysis systems, and excitation sources that emit photons (See ).

1.3 Detailed data analysis methods are not described or recommended, as they may be unique to a particular analysis problem. Some applications may require the use of spectrum deconvolution to separate partially resolved peaks or to correct for matrix effects in data reduction.

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
