ASTM D6138 - Determination of Corrosion-Preventive Properties of Lubricating Greases Under Dynamic Wet Conditions (Emcor Test)

Significance and Use  

5.1 This test method is used to assess the ability of grease to prevent corrosion in rolling bearings operated in the presence of distilled water, sodium chloride solution, or synthetic sea water. It is used for development and specification purposes.

1. Scope

1.1 This test method covers the determination of corrosion-preventive properties of greases using grease-lubricated ball bearings under dynamic wet conditions.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
