You are right.The grease compatibility tests are d<strong>on</strong>e as per ASTM D 6185 in<br />

which Penetrati<strong>on</strong>, drop point and high temperature tests are d<strong>on</strong>e <strong>on</strong><br />

90:10,10:90,25:75,75:25 and 50:50 mixtures of greases.Depending up<strong>on</strong> <strong>the</strong><br />

criticality of applicati<strong>on</strong> Tribology tests are also recommended.<br />

Normally,if <strong>the</strong> bases are same <strong>the</strong>y should be compatable.<br />

There is also a chart showing which grease is compatable with o<strong>the</strong>r grease.<br />

Thanks<br />
