Prior testing, accompanying documents have checked for the manufacturer's recommenda
tions regarding maintenance and repair, including conditions and precautionary measures.
Lim iting valu for the insulating resistance are not specified the DIN VDE 0751-1 standard
(issue 2008).3 Test acco 0751-1
The DIN VDE 0751-1 standard applies for tests medical electrical devices, medical electrical
systems parts those devices systems complying with the DIN 60601-1 (VDE0 750 Part
1) standard which are carried out prior commissioning, inspection, maintenance during periodic
testing order evaluate the safety those devices systems their parts.1)
The tests must carried out qualified personnel.
(taken from VDE 0751-1: issue 2008-08, section 4. Insulation measurement must not carried out,
if excluded the accompanying documents according the manufacturer's specifications. Personnel evaluating safety must able detect possible consequences and dangers
that might caused devices not complying with the requirements.
(taken from VDE 0751-1:2001-10, section 1. Here, possible refer recommendations the manufacturer previously
measured values. For devices which
are not built according DIN 60601-1 (VDE 0751 Part 1), this standard can applied anal
