11.3 Test Procedure according to VDE 0751-1
The DIN VDE 0751-1 standard applies for tests of medical electrical devices, medical electrical
systems or of parts of those devices or systems complying with the DIN EN 60601-1 (VDE0 750 Part
1) standard which are carried out prior to commissioning, inspection, maintenance or during periodic
testing in order to evaluate the safety of those devices or systems or their parts. For devices which
are not built according to DIN EN 60601-1 (VDE 0751 Part 1), this standard can be applied anal-
ogously under consideration of the safety standards applying to the manufacturing of the device.

Prior to testing, accompanying documents have to be checked for the manufacturer's recommenda-
tions regarding maintenance and repair, including conditions and precautionary measures.
In the current issue of the DIN VDE 0751-1 standard, the measurement of the insulating resistance
is required, if it is considered to be convenient. Insulation measurement must not be carried out,
if it is excluded in the accompanying documents according to the manufacturer's specications.
Limiting valuesfor the insulating resistance are not speciedinthe DIN VDE 0751-1 standard
(issue 2008). Here, it is possible to refer to recommendations of the manufacturer or to previously
measured values. The DIN VDE 0751-1 standard recommends the following order of the tests to
