Electromagnetic Compatibility (EMC)

Electromagnetic compatibility (EMC) describes the ability of a product to operate reliable in an electromagnetic environment without affecting it with unwanted electromagnetic phenomena.


We are accredited by the > DAkkS and recognized by the IECEE in the > CB Scheme. In addition, we are a member of the > Third Party Test Data Program of Unterwriters Laboratories (UL).


As > designated technical service (category A, B und D) of the Kraftfahrt-Bundesamtes (KBA) we ware authorized to carry out EMC tests for EC type-approvals, UN ECE licenses and national road traffic regulations.

We support you in the creation of a test plan tailored to your requirements, both for normative tests and for development tests. Please introduce us to your product.

EMC Services

We investigate the electromagnetic compatibility of assemblies, devices and systems for use in the medical, automotive, railway, industrial and laboratory sectors. In our anechoic chambers (3 m / 10 m working section), we can test both small and larger products with a weight of up to 3 t.
