Analytical laboratory: accreditation renewed

The accreditation of our oils analysis laboratory in Martigny was renewed last January. Following their inspection, the experts found that our organisation fully satisfied the requirements of standard SN EN ISO/IEC 17025:2018.

The accreditation was therefore renewed until March 2021. It provides our clients with an assurance of quality, as they can be certain that our processes meet the highest standards.

One of our clients is Swiss railways (SBB).  They require very high-quality analyses of their locomotive traction transformers. Some 300 - 400 samples, taken throughout the year, are therefore processed in our laboratory. We have provided this service to SBB for ten years, analysing oils which come from all over Switzerland.

Finally, during this difficult period of the COVID-19 pandemic, our laboratory has produced several dozen litres of hydro-alcoholic gel for the use of HYDRO Exploitation SA’s staff across our many sites.
