SCOPE 1.1 Purpose.- This standard describes the methods of lu

4、bricating fire control instruments during final assembly or component sub-assembly. 1.2 Classification.- Lubrication shall be in accordance with Method 1 or 2 as designated on the applicable drawing or desgn document. The se- lection of the lubrication method is determined by the nature of the parts

5、, their location and t.he materials, _. as follows: Use Method 1 for - Lubrication of bearing and mating surfaces where degradation of optical, electrical or physical properties of the system may result from contact with the lubricant or its volatile products, or incompatible plastic parts; for lubr

6、ication of certain rubber parts such as 0- rings or other seals. Use Method 2 for - Normal lubrication purposes as applied to gears, bearings and other moving parts, where contamina- tion of a critical optical surface, or an in- compatible plastic or rubber material is con- sidered remote. 1.3 Appli

7、cation.- Lubrication of fire control instruments and equip- ment in accordance with this standard is intended to insure their proper operation under adverse environmental conditions for the maximum possible maintenance-free duration. This standard is intended to cover only general lubrication method

8、s applicable to sliding, rolling, or rotating movements, and rubber seals normally encountered in precision fire control instrument design. It does not cover extremely delicate applications such as watches and clocks; heavy duty mechanisms such as generating units, trailers, etc.; self-lubrieated be

9、arings and special systems utilizing dry-film or powder lubricants. 2.

14、es shall be removed using a suitable cleaning procedure, The use of aluminum oxide abrasive cloth is prohibited on bearing surfaces. Bietal parts to be used in optical assemblies shall be cleaned by vapor- phase degreasing wherever possible; where impracticable , solvent soaking, scrubbing and wipin

15、g is permissible. Parts received packaged with a pre- servative or grease other than the lubricants specified in this standard or on the applicable drawing shall be rough cleaned in a separate unit in order to prevent excessive contamination of the cleaning bath. Parts shall be thoroughly dried befo
