The qualification system is used when purchasing high-cost strategic items, but also lower-cost items that must
meet technical requirements, compliance with which can only be determined after extensive testing.

In addition to supplier qualification, product approval may also be required. The conditions for supplier
qualification and product approval are included in the technical specifications.

List qualification systems

The qualification system was introduced after the revision of the public procurement rules with Directive
2004/17/EC of the European Parliament and of the Council, allowing candidates to be selected on the basis of
qualification. This pre-selection makes it possible to assess candidates' competencies in advance.
A certificate is valid and renewable for six years. You will be sent the questionnaire again six months before it
expires. SNCB evaluates each case for extension separately, and may conduct a new audit.

SNCB reserves the right to withdraw qualification for:

  • Changes to a product or process that have not been reported
  • Processes, products, controls and tests, etc. that no longer comply with the technical specifications
  • Supplier bankruptcy
  • Repeated quality or delivery issues

If a technical specification for the product approval tests changes, the new field tests and tests needed to
maintain your approval as a qualified supplier will be invoiced to SNCB. The supplier may decide to withdraw its

The new tests are carried out by SNCB or, with the agreement of SNCB, by the supplier or a third party. SNCB
may decide to carry out these tests only upon taking receipt of the product concerned. In such cases, approved
products remain approved at least until such tests are carried out.

As a supplier, you must report any changes to your product, especially if they are relevant to product approval.
SNCB will decide whether new tests should be carried out on the product concerned.

If you wish to obtain approval for other products in accordance with other technical specifications, you must
submit a new qualification application.

This is possible, but each site must obtain qualification separately.
A file can be opened free of charge. A supplier audit in a European Union or European Free Trade Association
(EFTA) member state will be invoiced to SNCB. If an audit is conducted in a country outside of the EU or EFTA,
the costs for accommodation and travel shall be borne by the supplier.

The cost of field tests and/or laboratory tests as part of product approval are borne by SNCB if the product is tested in the SNCB Group laboratory and all the requirements of the Technical Regulations are met. The costs are borne by the supplier if one or more technical requirements are not met or if the tests are not carried out in the SNCB Group laboratory.

Prototypes for field tests or laboratory tests must be made available to SNCB at the supplier's expense. Exceptions to these rules are noted in the technical specifications. The costs are always invoiced in advance by SNCB.

SNCB does not require suppliers to have an ISO 9000 quality certificate (or equivalent). However, suppliers must have an effective quality policy in place and demonstrate that the products or services comply with SNCB requirements.
