The RDW verifies whether you have taken adequate measures to ensure that vehicles, systems, parts or technical units are produced conform to the approved type. This procedure is referred to as Conformity of Production (CoP).

Starting 2021, we have introduced a new monitoring procedure which aims at a better verification of In Service Conformity (ISC) of vehicles with e4 emission type approval. This means that RDW will conduct emission tests in order to verify that vehicles in use are still in compliance with issued e4 emission type approvals on a yearly basis. Therefore, from now on we are also responsible as a monitoring authority for the relevant environmental requirements.
