The European Machinery Directive (2006/41/EC) together with harmonized standards forms the framework for functional safety. The European Machinery Directive obliges all manufacturers worldwide who market their machines in the European Economic Area for the first time to satisfy uniform safety requirements. The scope of the Machinery directive are determined below:

  • Machinery
  • Interchangeable equipment
  • Safety components
  • Lifting accessories
  • Chains, ropes and webbing
  • Removable mechanical transmission devices
  • Partly completed machinery

The European Machinery Directive (2006/41/EC) is not the only one applicable Directive. Different directives may be involved during the analysis of the machine:

  • Low-voltage Directive ( 2006/95/EC)
  • EMC Directive (2004/108/EC)
  • ATEX product Directive (94/9/EC)
  • Pressure Equipment Directive(97/23/EC)

ROSAS offerings a unique knowledge to correctly apply the different Directives and Harmonized Standards. ROSAS uses different methods and processes in order to fully comply with all the applicable Directives.

Methods and Processes
  • Risk Assessment

  • ISO 12100
  • ISO 13849 (replacement of EN 954-1)
  • IEC 61508
  • IEC 61511
  • IEC 62061
  • IEC 61800-5-2
  • IEC 60204-1

Smart Mobility

The brand new Smart Mobility department of ROSAS is the solution to the increasing demand from the autonomous vehicle industry in the context where car manufacturers integrate more and more automated driving functions in vehicles. The industry is currently taking the first steps towards marketing real autonomous vehicles where driver assistance will be conditional or optional in the future. Such a system must meet standards in order to ensure a high level of safety and cybersecurity. The Smart Mobility department is responsible for guiding partners towards the certification of their systems according to the updated and new standards. The publication at the end of December 2018 of the 2nd revision of the automotive functional safety standard (ISO 26262:2018), the revision of SOTIF (Safety of the Intended Functionality) standard, early 2019 (ISO/PAS 21448:2019) and the publication of an automotive cybersecurity standard (ISO-SAE 21434) end 2019 – early 2020 offers for the first time a guidance for the development of autonomous vehicles systems.

Methods and Processes
  • HRA (HARA)
  • System FMEA, Design FMEA, FTA, FMEDA
  • Verification & Validation of the SOTIF (Area 2 & Area 3), STPA
  • ISO 26262, ISO/PAS 21448 (SOTIF), ISO-SAE 21434
