IIS Group operates in the field of certification through its own company IIS CERT, providing its Clients with certification of quality management systems, environment and safety, manufacturing processes, materials, products and personnel.

A distinguishing feature since the establishment of the IIS Group is the strict link with the industrial world in materials production, fabrication processes, in service requirements and performances of components and structures, knowledge and consistent updating about standards and regulations: this feature is perceptible through the daily activity of our Inspectors and Auditors and their hands on experience.
