EN60601-1 (Medical Safety) Appendix C provides a list entitled "Sequence of Testing". This list is used during the course of the safety investigation on the device. It follows as: C24: Cont. leakage currents and patient auxiliary currents at operating temp C25: Dielectric strength at operating temp C26: Humidity preconditioning treatment C27: Dielectric strength test (cold condition after humidity conditioning) C28: Leakage current test after humidity preconditioning treatment
In our production testing we perform a high potential dielectric strength test first followed by a leakage current test. Our high potential tester has a ground continuity circuit and will warn the operator if the safety ground circuit is not in place (open). -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Friday, March 17, 2000 7:37 AM To: Bruce Touzel; Art Michael Cc: [email protected]; Martin Rowe (TMW) Subject: Re: SAF: Insulation resistance and hipot tests Folks: EN 60204-1 also specifies an insulation resistance test. Depending on the standard, they tell you the sequence of the various safety tests. For example, in EN 60204-1, clause 19.1 (the test clause) states: "When these test are performed, it is recommended that they follow the sequence listed." For EN 60204-1, it is Ground continuity, then Insulation resistance, then Hipot, then cap discharge. I hope this helps.
