HEI-95 Electrical Safety Tests

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of HEI-95 testing. This standard describes the electrical safety tests commonly found in medical equipment safety testers.

The basic principle behind the philosophy of electrical safety is that in the event of a single abnormal external situation or the failure of a single means of protection against a hazard, no safety hazards should arise. Such conditions are called "single fault conditions" (SFCs) and include interruptions of the protective earth conductor or a supply conductor, the appearance of an external voltage on an applied part, failure of the basic insulation or temperature limitation. devices.

Where a single fault condition does not apply, equipment is said to be in "normal condition" (NC). However, it is important to understand that even in this case the performance of certain tests may compromise the means of protection against electric shock. For example, if the earth leakage current is normally measured, the impedance of the measuring instrument in series with the protective earth conductor means that there is no effective additional protection against electric shock.

Many electrical safety tests are performed under a variety of single fault conditions to verify that there is no danger even if these conditions occur in practice. Often times, it is the case where single fault conditions represent the worst case and produce the most unfavorable results. Clearly, the safety of the equipment under test can be compromised when such tests are performed. Personnel performing electrical safety tests should be aware that normal means of protection against electric shock are not necessarily effective during the test, and therefore must take the necessary precautions for their own safety and the safety of others. In particular, the tested equipment should not be touched by anyone during the safety test procedure.
