IEC 60601-2-10 - Accuracy of Pulse Parameters - Required Measurement Uncertainty

Dear all,

I have the latest german consolidated edition DIN EN 60601-2-10:2017 (incl. A1). In cl. 201.12.1.10" "Pulse parameters" it states a maximum allowed measurement error of only 1%. I have the previsous edition of the IEC version, where 10% measurement error were allowed.

In the change notices there is nothing mentioned regarding this change. Does anyone have the latest IEC version and can tell me if this is maybe onyl a mistake during translation to the german DIN EN version?

I have BS EN -2-10:2015 + A1:2016

from that:
...shall not deviate by more than ± 20 % when measured with a load resistance within the range specified in the ACCOMPANYING DOCUMENTS
Compliance is checked by measurement with an error not exceeding ± 10 %.

It seems to be a double mistake. A general rule of thumb is to have measurement equipment that is 5 times more accurate than the specification. So, if the allowable limit for the equipment is ±20%, the reference equipment (in total) should be ±4%. Neither 10% or 1% make sense ....
