Quality & Certification

National and international standards set the framework. In the early 70s, the QM system was built according to the standard AQAP1. In the following years, numerous international standards and a variety of customer requirements in the quality management system were integrated.

  • CE Marking

    CE Mark

    Those products from the E-T-A programme which are subject to the European Union EMC Directive have been CE marked since early 1996 to demonstrate compliance. Declarations of conformity contain the necessary supporting evidence.  In addition, from January 1997, models covered by the Low Voltage Directive have also been CE marked.

    CE marking is the responsibility of individual manufacturers and should not be confused with formal approval logos, the use of which is administered by recognised test authorities.
