In section 9.1 (Procedure for Acid Number), it directs the user that if the solution, . . . becomes green or green-black, proceed as directed in Section 10.. Section 10 is the Procedure for Base Number. The issue is that for some sites, only the acid number is required for the product specification, and therefore analysis for base number is not needed. A proposed revision is identified that provides users of the method with the option of not proceeding to the base number procedure if it is not required.
