DAkkS Accredited Test Laboratory

Our in-house test laboratory is accredited by the German accreditation body DAkkS, according to DIN EN ISO 17025:2018 for EMC, environmental simulation tests and safety of electrical equipment.

Qualified Test Reports for Railway and Industrial Applications

We are accredited according to DIN EN ISO/IEC 17025:2018, to supply recognized test reports for further approvals of the end system. The accreditation covers tests regarding EMC, environmental simulation and safety of electrical equipment for the railway and industrial markets. We are qualified to deliver accredited test reports that can be produced at short notice or can be better planned, without customers or duagon itself being dependent on an external laboratory with correspondingly long waiting times.


Additional Qualification: Compliance with EN 50124-1

Our lab complies with EN 50124-1, which specifies the insulation coordination of air and creepage distances in railway applications to ensure electrical safety and to avoid short circuits or even oversizing of the insulation. Across Germany, only about 5 companies are accredited for EN 50124-1.

Our quality management system includes cable monitoring to check the suitable temperature and humidity in the laboratories as well as DAkkS-accredited measuring instruments with sophisticated DAkkS calibration.


Industry-Specific Certifications

In addition to the DAkkS accreditation, we already have industry-specific QM certifications in railways (IRIS - ISO/TS 22163), and experience in the functional safety sectors according the relevant standards DO-254 (DAL-A), IEC 61508 (SIL3), EN 50128 (SIL4) and EN 50129 (SIL4).

Capacities also cover the area of electrical safety: testing of devices for electrical safety, overvoltage, short circuit, personal protection, mechanical hazards.


Our quality management comprises all company areas accounting for the service aspect: design, production and maintenance, marketing and sales, order desk, production planning, buying etc. It focuses on the customer, who is to be satisfied on a long-term basis by the highest quality possible of both products and services.

Certification partner is DQS, a part of the international DQS-UL Group.

ISO 9001

Official certification according to DIN EN ISO 9001 is in place since 1997. It has been replaced by the most recent version ISO 9001 in 2015.

IRIS for Railway

Official certification according to IRIS (International Railway Industry Standard) DIN ISO/TS 22163 in place since 2009. It emphasizes our excellence for the transportation market.

E-Mark for Vehicles

An extended ISO 9001 certificate proves that the management system fulfills the requirements of international traffic laws. This entitles us to apply for a permit for products of the automotive market at the responsible authority.
