In order to assist the SCHÖCK company in getting the renewal of its technical certification for thermal breakers, NECS' mission was to verify the mechanical resistance of the breakers under various concomitant actions.
- Thermal expansion due to climate solliciations,
- Concrete shrinkage,
- Earthquake (only for the case of external isolation).
The aim of the study was to obtain the renewal of the technical certification in order to grant the use of SCHÖCK's products in France seismic areas.
