STORAGE STABILITY OF FLUIDS AND LUBRICANTS PART II - ROOM TEMPERATURE STORAGE OF AIRCRAFT GREASES

摘要

Eleven greases qualified under Military Specifications MIL-G-3273, MIL-L-3545, MIL-L-4343, MIL-G-74.21, and MIL-L-7711, and supplied by various manufacturers were placed in storage at room temperature for two years. The greases were examined periodically to determine if storage had affected any of their properties.nAt the termination of two years of storage, it was discovered large changes in consistency had occurred in three out of four Specification MIL-L-7711 greases. The properties of these greases were no longer within specification limitations. All other greases maintained minimum require-ments.
