Accredited Test House for MOST Compliance

RUETZ SYSTEM SOLUTIONS is a MOST Cooperation accredited test house. As a member of the MOST Cooperation and an active member of the »MOST Compliance Technical Group«, we actively help design the test specification for all MOST scopes. We test and certify MOST25, MOST50 and MOST150  (oPhy and cPhy) based control units with respect to the following scopes:

  • MOST Full Physical Layer Compliance
  • MOST Full Electrical Physical Layer Compliance
  • MOST Optical Limited Physical Layer Compliance
  • MOST Core Compliance und Extended Core Compliance MHP und ECL
  • MOST Profile Compliance

Accompanying Certifications

For us, it is important to consult with and accompany our customers throughout the total certification phase. Therefore we support carmakers and suppliers with accompanying certifications to identify errors at even preferably early design stages. In addition to formal tests, we offer pre-tests related to single development stages and knowledge transfer packages (Best Practice).

Carmaker-specific Tests

As the compliance tests are a basis qualification for system integration, RUETZ SYSTEM SOLUTIONS offers individual tests for carmakers and suppliers. For MOST or Automotive Ethernet, these so-called »Application Recommendations« or »Test Check List« (e.g. BMW Ethernet Test Check List) are based on the specifications of the particular carmaker, are developed in cooperation with them and are converted to automated tests.
