It is not the intent to limit or restrict tests to only those described herein. Variations in test procedures may exist without violating the intent of this standard. Exceptions may be taken if agreed upon by the parties involved without sacrificing the validity of the applicable parts of the standard.

Purpose

This standard provides uniform procedures for mechanical and other pump performance testing and for recording of the test results of air-operated diaphragm and bellows pumps.
