Standard tests for electrical safety
When testing electrical safety, a fundamental distinction is made between different test methods:
- Typprüfung, die ein Erzeugnis vor der Serienfertigung zu durchlaufen hat.
Hierbei handelt es sich um eine umfangreiche Prüfung, bei der sowohl mechanische wie elektrische Komponenten begutachtet werden. Die Tests umfassen elektromagnetische Verträglichkeit, Temperaturverhalten, Verhalten bei Druck- und Feuchtigkeitseinflüssen, usw. und sind auf ein oder wenige Baumuster (Prototypen) beschränkt. Solche Prüfungen werden meist von akkreditierten Prüfstellen (TÜV, DGUV …) durchgeführt und zertifiziert. - Product testing (100 % production testing)
In routine testing, products from ongoing production are tested. The inspection takes place at the end of production (end of line). In this way, the manufacturer guarantees that each product placed on the market complies with the safety provisions of the relevant standards. Compliance with the “Basic (Safety) Requirements” is regulated in Europe by EU directives, which also form the basis for CE marking, among other things.
More tests for electrical safety:
- Protective conductor test
- High-voltage test(hipot test)
- Insulation strength, insulation resistance
- Dielectric strength or electric strengh
- Leakage and leakage current measurement
