The purpose of the Hydraulic Institute (HI) pump test laboratory approval program is to establish a pump test laboratory audit and inspection program to approve a pump test laboratory's ability to test the performance of certain products to test standard(s), and adhere to the requirements of an international test laboratory accreditation standard (ISO 17025) concerning test measurement equipment.

Participants in the pump test lab approval program include any organization, such as a corporation, research institution, laboratory, etc., whether domestic or international, that have the capability to test pumps and extended products to applicable test standards.
