They are intended for use in fixed or moving parts of the aircraft structur

8、e and their control mechanisms. They shall be used in the temperature range -54C to +150C. However being lubricated with the following greases: - grease as per MlL-G-23827 (Code A): operating temperature range -73C to +121 “C or - grease as per MlL-G-81322 (Code B): operating temperature range -54C

9、to +177“C. Their field of application when lubricated with grease Code A is limited to +121 “C. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications. These norma- tive references are cited at the appropriate places in the text an
