Marking follows assessment

CE marking, the declaration of conformity and the passport record must agree, because each points to the same assessment file. Keep conformity evidence and passport data cross checked, and keep corrective action visible.

Useful starting points

  1. Map the assessment route for the model.
  2. Check marking, declaration and record agree.
  3. Record surveillance requests and responses.
