Euro V and Euro VI heavy trucks: a procurement checklist
Euro V and Euro VI heavy trucks: a procurement checklist
Distinguish heavy-duty Euro V/VI from light-duty Euro 5/6, then compare approval evidence, the exact emissions system and the support needed on your route.
Identify the approval framework
Heavy-duty Euro V and Euro VI use Roman numerals. Light-duty Euro 5 and Euro 6 belong to a different approval framework. Ask for the vehicle category and the regulation recorded on the approval document; a sales label alone is insufficient.
| Claim in the offer | Framework to identify | Procurement action |
|---|---|---|
| Heavy-duty Euro V | Historical EU framework: Directive 2005/55/EC and implementing Directive 2005/78/EC. | Request the precise approval and amendments for the proposed vehicle or engine. |
| Heavy-duty Euro VI | Regulation (EC) No 595/2009 and implementing Regulation (EU) No 582/2011. | Record the approved type, applicable stage and document revision. |
| Light-duty Euro 5 / Euro 6 | Regulation (EC) No 715/2007. | Check the approval scope; this label does not establish heavy-duty Euro V/VI approval. |
- Keep the regulation number, amendment or stage, approval number and issuing authority together.
- If a UN Regulation No. 49 approval is supplied, record its amendment series and scope; the regulation number alone does not identify a Euro stage.
Match the engine, controls and aftertreatment
Euro VI introduced tighter pollutant-emission requirements than Euro V. Its framework covers on-board diagnostics (OBD), durability and in-service conformity. For either emissions level, compare one documented system in its vehicle installation. A catalogue emissions range does not identify the configuration being offered.
- Request the engine type or family, calibration identification and fitted aftertreatment details.
- Ask the supplier to map the approval documents to the quoted vehicle, including installation conditions.
- List any SCR, particulate filter and other fitted devices explicitly; confirm the actual equipment and maintenance instructions.
Check fuel, consumables and workshop support
Shortlist configurations whose operating requirements can be met on the intended route. Give the supplier the fuel specification, duty cycle and workshop arrangements, and obtain a written assessment for the proposed system.
- Confirm the manufacturer's permitted fuel specification, including sulphur requirements, against the fuel that will actually be purchased.
- Where reagent is required, confirm its specification, storage, replenishment and local supply.
- Where a particulate filter is fitted, obtain regeneration and cleaning instructions for the expected work pattern.
- Confirm diagnostic access, fault-response procedures, service parts, maintenance intervals and the party responsible for support.
Close the document checklist before ordering
Assess destination acceptance separately from the emissions label. Confirm current import and registration requirements for the exact vehicle with the relevant authority or a qualified local adviser. This guide does not establish Euro VI availability or certification for any vehicle on this website.
- Agree the exact model, engine, emissions configuration and specification revision in writing.
- Collect the relevant approval documents and check that their identities match the order; reconcile the delivered vehicle identifiers at inspection.
- Record the required destination documents, their issuer and who will obtain them.
- Resolve missing documents or operating support before accepting the configuration; retain the agreed fuel and maintenance requirements with the order.
