DIN EN IEC 61557-16:2025-09

This part of IEC 61557 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. The aim of this document is to achieve comparable measurement results and additional safety for the person conducting the test and to design the electrical stress on the test specimen in such a way that it is not damaged. The standard differs from DIN EN 61557-16 (VDE 0413-16):2015-12 as follows: 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 4.3.3 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. This part of IEC 61557 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.
