Quality is not a laughing matter,

Lafer one is certified.

Total quality is a daily target for Lafer.

Its production system has been verified by the most important institutions in charge that granted the company the UNI EN ISO-9001 certification.

Additonal tests carried out on cabinets perfomances, accessories and internal components have been certified at CESI Institute. By virtue of these acknowledgements, all Lafer products can display the CE marking at the customer’s request.

All LAFER cabinets have been conceived and designed in full compliance with national and international regulations in force (CEI EN 61439-1/2, CEI EN 60529).

LAFER cabinets have been tested and certified according to type tests established by the law and their performances are guaranteed under real operating conditions.

All internal components and accessories used for the cabinet manufacturing are compliant with type tests as well.

Calculation methods used for the designing and the manufacturing of LAFER distribution systems too follow CEI 17-52 and CEI EN 60865 norms. LAFER also declares that, as required by the norm, the whole designing process of its distribution systems is based on the extrapolation of a set of type tests.

LAFER cabinets have been subjected to the following type tests established by the norms:
