Contracting entities may require that economic operators provide a test report from a conformity assessment body or a certificate issued by such a body as means of proof of conformity with requirements or criteria set out in the technical specifications, the award criteria or the contract performance conditions.

Where contracting entities require the submission of certificates drawn up by a specific conformity assessment body, certificates from equivalent other conformity assessment bodies shall also be accepted by the contracting entities.

Contracting entities shall accept other appropriate means of proof than those referred to in paragraph 1, such as a technical dossier of the manufacturer where the economic operator concerned had no access to such certificates or test reports referred to in paragraph 1, or no possibility of obtaining them within the relevant time limits, provided that the lack of access is not attributable to the economic operator concerned and provided that the economic operator concerned thereby proves that the works, supplies or services meet the requirements or criteria set out in the technical specifications, the award criteria or the contract performance conditions.

Member States shall make available to other Member States, upon request, any information related to the evidence and documents submitted in accordance with Article 60(6), Article 61 and paragraphs 1 and 2 of this Article. The competent authorities of the Member State of establishment of the economic operator shall provide this information in accordance with Article 102.
