The objective of the framework agreement is to cover the Norwegian Defence ́s need for chemicals for the maintenance and repair of aircraft, including aircrafts and helicopters in peace, stand-by situations, armed conflict, crisis and war. The aircraft shall also be interpreted as including missiles.  The framework agreement shall ensure access to products used for maintenance and repairs, in accordance with the requirements of military airworthiness regulation.  See part II General Contract Terms, Annex B (Requirement Specifications) and Annex D (Price Form and Product Form) for further details on the extent of the procurement. The estimated value of the framework agreement is NOK 50-75 million excluding VAT over the maximum duration of the framework agreement. The estimate is made based on historical figures and/or expected future use according to the contracting authority ́s best judgement. The forecast documentation is uncertain due to large product breadth, phasing out/phasing in air systems and a lack of history for new platforms. Furthermore, global development, political guidelines, stand-by and changes in the composition of aircraft at the contracting authority can lead to changes in future consumption. The maximum value of the framework agreement is NOK 95 million excluding VAT over the maximum duration of the framework agreement.
