The European Commission's Directorate-General for Internal Market, Industry, Entrepreneurship and SMEs is seeking input from stakeholders. It regards CoP checking procedures for replacement silencers of vehicle categories M1 and N, as well as the technical feasibility for the improvement of sound level performance through better CoP.

The European Commission has assigned EMISIA (GR) and  HSDAC (DE) with the task to perform “a technical and financial investigation on CoP checking procedures for replacement silencing system as separate technical unit for vehicles of categories M1 and N”. The investigation takes into account the current availability, technical progress and future perspectives, as well as the opinion of

  • the industry
  • technical services
  • type approval authorities
  • other national authorities

The questionnaire aims at collecting input with regard to various aspects of CoP checking procedures for replacement silencing systems, such as

  • current types of CoP requirements
  • authorities involved
  • enforcement level of the CoP
  • effects on product conformance
  • future proposals
