After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the
14、 approval of the National Associations and the Official Services of the member countries of AECMA, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2006, a
15、nd conflicting national standards shall be withdrawn at the latest by October 2006. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. Ac
