BS EN IEC 61267:2026

This standard BS EN IEC 61267:2026 Medical diagnostic X-ray equipment. Radiation conditions for use in the determination of characteristic is classified in these ICS categories:

• 11.040.50 Radiographic equipment

IEC 61267:2025 applies to test procedures which, for the determination of characteristics of systems or components of medical diagnostic X-ray equipment, require well-defined X-ray radiation conditions. This document deals with methods for generating X-ray radiation conditions which can be used under test conditions typically found in test laboratories or in manufacturing facilities for the determination of characteristics of medical diagnostic X-ray equipment. IEC 61267:2025 cancels and replaces the second edition published 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) removing former Annex C “Measurement of the practical peak voltage”; b) inserting informative “Tabulated values for the squared signal-to-noise ratio per air kerma (SNR2in)” and normative “Additional X-ray radiation conditions as used in mammography and determination of the corresponding nominal aluminium half-value layers”; c) revision of X-ray radiation conditions; d) new method for verification of X-ray radiation conditions; e) change of term definitions.
