(1) A dynamic purchasing system is a short-term, exclusively electronic procedure for the procurement of performances that are generally available on the market, for which the characteristics that are generally available on the market satisfy the requirements of the public contracting authority.
(2) An electronic auction is a repetitive electronic procedure for determining the most economically advantageous tender. Each electronic auction is preceded by a complete initial evaluation of all tenders.
(3) An electronic catalogue is a list of the supplies, works and services to be procured, which is prepared in an electronic format based on the tender specifications. It can be utilised particularly for concluding framework agreements and can include illustrations, price information and product descriptions.
(4) A central purchasing body is a public contracting authority that, on an ongoing basis, purchases supplies and services, awards public contracts or concludes framework agreements on behalf of other public contracting authorities (centralised purchasing activity). Public contracting authorities may procure supplies and services from central purchasing bodies or award contracts for supplies, works and services through central purchasing bodies. Public contracts for carrying out central purchasing activities may be awarded to a central purchasing body without conducting a procurement procedure in accordance with the provisions of this Part. Services contracts of this type can also include consulting and support services for the preparation or execution of procurement procedures. Parts 1 to 3 shall remain unaffected.
