MEN: accreditation of in-house test laboratory to DIN EN ISO/IEC 17025:2005

The MEN in-house test laboratory has been accredited by the German accreditation body DAkkS. With accreditation according to DIN EN ISO/IEC 17025:2005, MEN can now 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 market and industry.

This means that MEN can now deliver accredited test reports that can be produced at short notice or can be better planned, without customers or MEN itself being dependent on an external laboratory with correspondingly long waiting times. This allows MEN to add another piece to its integrated supply chain.

As a special feature, compliance with EN 50124-1 was also confirmed, which specifies the insulation coordination of air and creepage distances in railway applications in order 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. The MEN QM 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.

Within only 14 months after the kick-off the goal was reached – the complex accreditation was completed. This was only possible in the short time since industry-specific QM certifications from the aerospace (EN/AS 9100), railway (IRIS – ISO/TS 22163) and experience from the safety sector according to DO-254 and for Safety Integrity Level up to SIL 4 were already available.

Capacities have also been expanded, e.g. to cover the area of electrical safety: testing of devices for electrical safety, overvoltage, short circuit, personal protection, mechanical hazards.
