Owing to the nature of its activity, SFZ had to quickly implement a Quality Assurance System in line with the requirements of the pressurised devices sector. In 1987, it drafted an ASME Quality Control manual, established as part of the process for obtaining the ASME U-Stamp certification .


The first ISO 9001 certification was obtained in 1996.


Following the application of the European Pressure Equipment Directivde (PED), SFZ has obtained certifications based on modules H and H1 in 2002.

SFZ is also a member of the Association Euro-Qualiflex, the European Association of Manufacturers of metal expansion joints.
