Determination of acid number

Read our primer articles on Oil Analysis and Tribology

Can someone tell me the method to determine acid number in crude oils by pH metric titration. If possible please quote the reference also. Thanks

Petroleum industry uses IP 1B or ASTM D 664 for testing TAN of lubes.

Sorry I am not able to tell the test method off hand.
