Electrical equipment testing and component reliability

Electric equipment testing covered by the Low Voltage Directive according to the European Standards.

About this service:

Electric equipment testing covered by the Low Voltage Directive according to the European Standards which assumes its compliance with the essential safety requirements. Performance of this kind of testing is one of the pre-conditions for CE marking, within the scope of safety of electric equipment and its sale in the European Economic region.

Testing to monitoring and support to manufacturers in the validation of all stages of product from specifications through to review testing and product inspection.

This process may involve a product certification body. ISQ has agreements with the Certification Body CERTIF (Association for the Certification) for swifter certification process which issue the licenses based in the ISQ test reports.

Reliability testing of components or sub-assemblies in the electric and electronics field, automotive and aerospace.
