ANALYSIS OF THE EU HOMOLOGATION OF LPG/ CNG/ GNG COMPONENTS USED IN PROPULSION SYSTEM OF VEHICLE

RELEASE DATE:2021-06-16 16:02
BriefAccording to the EU vehicle framework regulation (EU) 2018/858 and its invocate Regulation (EC) No 661/2009 (the equivalent regulation is UN ECE R67 & R110), the LPG/ CNG/ GNG components used in the propulsion system of the vehicles of category M and N need to be type-approved as components firstly and then, they can be put on the EU market.



THE PROCEDURE OF TYPE APPROVAL
1. Documents Preparation
2. Factory Audit (This step can be exempted if the manufacturer hold a valid ISO 9001:2015/IATF1694:2009 certificate)
3. Samples Preparation and Testing
4. Assessment of Information
5. Issuance of Certificate
