The short rail system MiniRail has received ETN certification. The certification applies to the entire MiniRail System with the following modules:
In France, a ten-year insurance policy based on the DTU 40.35 norm (Domaine Technique d'Utilisation) is required. However, the DTU does not provide for any regulations for the mounting of a PV system, such as the MiniRail on the trapezoidal sheet metal.
The ETN certification and the various tests make it possible to complete the DTU 40.35 norm. The ETN is issued by the ALPES CONTROLES Bureau and is based on several mechanical load tests (e.g. pressure, vacuum) carried out at the CSTB. With the ETN certification, the MiniRail System for trapezoidal sheet metal roofs thus fulfils a compliant DTU fastening.
