Clarification on catalytic converter homologation

36317carFollowing recent developments surrounding the homologation of catalytic converters produced by a UK-based manufacturer, four emissions-based manufacturers have issued the following joint press release to clarify a number of key points.

Homologation independently as a direct fit manufacturer

Manufacturers of direct fit catalytic converters are able to obtain approvals for their own parts using their own R&D and choice of approval houses at significant costs. This process means that the manufacturer has complete ownership of the certificates. The homologation number allocated is unique to that manufacturer and can only be used by that producer. It is not possible to transfer those numbers to other part numbers/manufacturers without an application to the issuing body. The manufacturer is the owner of the certificate.

Homologation through extensions

Manufacturers who own their own approvals (as per point 1) are able to extend these certificates for additional brands for a small fee. The extension is made by the owner of the certificate applying to the issuing body for the additional brand to be added to the approval. Once accepted by the issuing body, a new homologation number and certificate is created and the certificate owner is able to manufacture and supply the applicable references noted on the documentation. The brand name does not have any control or ownership of the certificates.

Production Requirements

In both types of homologation, the requirement is on the owner of the certificate to use the correct raw materials and production methods to ensure performance is in accordance with the original tests conducted to achieve the certification.

If under an extension a manufacturer has only supplied a universal cat, allowing a brand to finish production, then the brand can only use these parts for the approval number to be valid. The brand cannot produce parts bearing the approval number using universal cats not supplied by the certificate owner.  If a brand does manufacture without the correct universal cat then the parts would, in effect, have no approval.

If a certificate is withdrawn, no further products can be produced and parts in the market may be subject to a restriction of sale depending on the reason for withdrawal.

Consequences for Non Conformity in the UK

The supply of non-approved catalysts (for vehicles first registered on or after 1/3/01), or catalysts without a valid homologation number, is currently up to £5,000 per offence.
