标准范围

IEC 60580:2019作为IEC 60580:2019 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60580:2019规定了剂量面积产品计的性能和测试，旨在测量患者在医学放射检查期间暴露的剂量面积产品和/或剂量面积产品率。本文件适用于以下类型的剂量面积产品计:a)通常用于医学放射检查期间剂量面积乘积测量的现场级剂量面积乘积计；b)通常用于校准现场级剂量计的参考级剂量面积积计。注参考级剂量区域产品仪表可用作现场-等级剂量面积产品仪表。本文件的目的是1)制定剂量区域产品仪表令人满意的性能水平的要求，以及2)标准化确定符合该性能水平的方法。指定了两个性能级别:-适用于现场级剂量面积产品测量仪的性能水平较低；-适用于参考级剂量面积产品仪表的更高水平的性能。IEC 60580:2019取消并取代了2000年发布的第二版，构成技术修订。与上一版相比，此版本包括以下重大技术变更:a)引入了具有更严格的不确定性容差的第二类设备；b)本文件已经扩展到包括除电离室之外的检测器；c)辐射质量已根据IEC 61267更新为新定义；d)增加了对剂量面积积率测量线性的要求；e)将腔室透光率要求从70%变更为60%。

IEC 60580:2019 is available as IEC 60580:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60580:2019 specifies the performance and testing of Dose Area Product Meters intended to measure Dose Area Product and/or Dose Area Product Rate to which the Patient is exposed during Medical Radiological Examinations. This document is applicable to the following types of Dose Area Product Meters:
a) Field-Class Dose Area Product Meters normally used for the measurement of Dose Area Products during Medical Radiological Examinations;
b) Reference-Class Dose Area Product Meters normally used for the Calibration of Field-Class Dosimeters.
NOTE Reference-Class Dose Area Product Meters can be used as Field-Class Dose Area Product Meters.
The object of this document is
1) to establish requirements for a satisfactory level of performance for Dose Area Product Meters, and
2) to standardize the methods for the determination of compliance with this level of performance.
Two levels of performance are specified:
– a lower level of performance applying to Field-Class Dose Area Product Meters;
– a higher level of performance applying to Reference-Class Dose Area Product Meters.
IEC 60580:2019 cancels and replaces the second edition published 2000, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) a second class of devices is introduced with tighter uncertainty tolerances;
b) this document has been expanded to include detectors other than ionization chambers;
c) radiation qualities have been updated to the new definitions according to IEC 61267;
d) a requirement on the linearity of the dose area product rate measurement was added;
e) changed chamber light transmission requirement from 70 % to 60 %.
