The safety certification of a system or an apparatus is often a challenge to be won, HINTSW - T & T Systems has a solid experience on the safety certification in the following areas:

  • the railway sector regulated by CEI EN 50126, CEI EN 50128 and CEI EN 50129;
  • the process and oil industry regulated by IEC 61511;
  • the command and control electronic systems regulated by IEC 60730 - Annex H;
  • the machinery regulated by CEI EN 62061;
  • the programmable electronic systems almost always regulated by IEC 61508.

In these areas HINTSW - T & T Systems provides its customers with all the support and know-how needed to successfully meet the challenge of certification.

If the system to be certified includes some software,to  which  security features are assigned, HINTSW - T & T Systems  is able to provide highly specialized support for the software safety certification activity, through the application of  Software Safety Life Cycle, in accordance to the applicable standards (eg: UL 1998, IEC 61508-3, IEC 61511, IEC 62061, IEC 50128, IEC 60730-1 Annex H, etc.), using all methods and techniques for the development and testing, required by those standards.

Finally, as part of the safety certification, HINTSW - T & T Systems performs all validation and verification activities (V & V) and, as an independent organization, can assume the role of "verifier", thus constituting a neutral interface, competent and economically advantageous in dealing with the certification body.
