标准摘要
[中文适用范围]: 本文件规定了用于非侵入性测量X射线管电压(最高150 kV)的仪器的性能要求及相关符合性测试。本文件还描述了校准方法,并提供了在不同于校准条件下进行测量时估计不确定度的指南。此类测量的应用包括诊断放射学(包括乳腺摄影、计算机断层扫描(CT)、牙科放射学和放射透视)。本文件不涉及此类仪器的安全方面。电气安全要求包含在IEC 61010-1中。 [外文原描述]: IEC 61676:2023 specifies the performance requirements of instruments as used in the non-invasive measurement of X-RAY tube voltage up to 150 kV and the relevant compliance tests. This document also describes the method for calibration and gives guidance for estimating the uncertainty in measurements performed under conditions different from those during calibration. Applications for such measurement are found in diagnostic radiology including mammography, computed tomography (CT), dental radiology and radioscopy. This document is not concerned with the safety aspect of such instruments. The requirements for electrical safety applying to them are contained in IEC 61010-1. IEC 61676:2023 cancels and replaces first edition published in 2002, Amendment 1:2008. This edition constitutes a technical revision. It includes an assessment of the combined standard uncertainty for the performance of a hypothetical instrument for the non-invasive measurement of the tube high voltage (in Annex A) which replaces Annex A of the edition 1.1 titled "Recommended performance criteria for the invasive divider". The contents of the corrigendum of January 2024 have been included in this copy.
