IEC 61557-16:20 23规定了适用于测试和测量设备性能的要求，以确定IEC 62353中描述的电气设备和/或医用电气设备保护措施的有效性。 本国际标准将与IEC 61557-1:20 19结合使用。 IEC 61557-16:20 23取消并取代2014年发布的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)4.2.1中医疗和非医疗电气设备不确定性要求的拆分； b)在4.2.1至4.2.7中增加了不确定度范围的定义； c）添加用于非4.2.1中的医疗器械； d)在4.2.1中增加了医疗应用在泄漏电流下的最大固有不确定性的限制； e)将4.2.3从测试插座改为维修用插座； f)在操作说明中添加警告； g)将前6.3整合到6.2中； h)更新表1； i)结构与整个IEC 61557系列的结构一致。

IEC 61557-16:2023 specifies the requirements applicable to the performance for test and measurement equipment in order to determine the effectiveness of the protective measures for electrical equipment and/or medical electrical equipment described in IEC 62353.
This International Standard is to be used in conjunction with IEC 61557-1:2019.
IEC 61557-16:2023 cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) splitting of uncertainty requirements for medical and non-medical electrical equipment in 4.2.1;
b) addition of a definition of ranges with defined uncertainty in 4.2.1 to 4.2.7;
c) addition of an optional measuring device (MD) for non-medical devices in 4.2.1;
d) addition of a limitation of the maximum intrinsic uncertainty for medical applications at leakage current in 4.2.1;
e) change of 4.2.3 from test sockets to sockets for service purposes;
f) addition of a warning in the operating instructions;
g) integration of former 6.3 into 6.2;
h) update of Table 1;
i) alignment of the structure with that of the whole IEC 61557 series.
