This test code describes tests for determining characteristics of hydraulic positive displacement pumps used on construction and industrial machinery as referenced in SAE J 1116. 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 \mDC (120 \mDF) and one at 82 \mDC (180 \mDF).

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; and g) flow compensator response and recovery.
