After inquiries and votes carried out in accordance with the rules of this Association, this standard has successively received the approval of the National Associati
19、ons and the Official Services of the member countries of AECMA, prior to its presentation to CEN. This standard was submitted for formal vote, and the result was positive. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endors
20、ement, at the latest by December1994, and conflicting national standards shall be withdrawn at the latest by December1994. According to the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Gr

22、stand only slow rotations and oscillations under load. They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms. The airframe rolling bearings defined in this standard are used from54Cto+150 C. However, being lubricated with the following grease
23、s: very high pressure grease, ester type (code A), operational range73 C to+121 C or very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range54 C to+177 C (seeEN3280), their field of application when lubricated with code A grease is limited to+121 C. 2 Normative
