IEC 61676:2023 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61676:2023规定了用于150 kV以下X射线管电压无创测量和相关合规性测试的仪器的性能要求。本文件还描述了校准方法，并给出了在与校准期间不同的条件下进行的测量的不确定度估计指南。这种测量的应用见于诊断放射学，包括乳房X线摄影、计算机断层摄影(CT)、牙科放射学和放射学。本文件不涉及此类仪器的安全性。适用于它们的电气安全要求包含在IEC 61010-1中。IEC 61676:2023取消并取代2002年发布的第一版，修正案1:20 08。本版构成技术修订版。它包括对用于非侵入式测量电子管高压的假设仪器性能的综合标准不确定度的评估（在附件A中），该仪器取代了标题为“侵入式分压器的推荐性能标准”的1.1版附件A。

IEC 61676:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

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".
