23、 4.2 Qualification Re-Qualification. All Army AGPU hydraulic filter elements shall require full qualification testing to this military specification sheet. To remain qualified, the manufacturer shall re-qualify every 3 years (even if the contract is awarded for a longer duration). Similarity and ana
24、lysis claims are not acceptable for qualification, however, AED will consider these claims for re-qualification purposes (every three years) as long as sufficient substantiation is provided. Contract awards shall be made only for such products as have been tested prior to the time set for opening of
25、 bids, been tested by an Army approved Laboratory and approved by AMCOM AED Propulsion Division for inclusion in the Army Aviation applicable Qualified Products Database (QPD). There shall be no exceptions to this requirement. The attention of the suppliers is called to this requirement and manufact
26、urers are urged to arrange to have the products that they propose to offer to the US Army tested for qualification, in order that they may be eligible to be awarded contracts or orders for the product covered by this specification.
