This test code describes tests for determining characteristics of hydraulic positive displacement pumps used on construction and industrial machinery as referenced in SAE J1116. These characteristics are to be recorded on data sheets similar to the ones shown herein. Two sets of data sheets are to be submitted: one at 49?C (120?F) and at 82?C (180?F). PURPOSE : This test code establishes conditions for pump tests@ outlines a procedure for tests@ and establishes a method of presenting pump test data. The procedure covers the following determinations: a. Derived capacity b. Delivery characteristics c. Power input d. Power loss e. Overall efficiency f. Pressure compensator response and recovery g. Flow compensator response and recovery
