This document specifies test procedures and a method of presenting the results concerning the parameters which define the main characteristics to be included in the literature from suppliers of regulators and filter-regulators conforming to ISO 6953-1.

The purpose of this document is to:

    facilitate the comparison of pressure regulators and filter-regulators by standardizing test methods and presentation of test data;

    assist in the proper application of pressure regulators and filter-regulators in compressed air systems.

The tests specified are intended to allow comparison among the different types of regulators and filter-regulators; they are not production tests to be carried out on each pressure regulator or filter-regulator manufactured.

ISO 6953-3 can be used as an alternative dynamic test method for flow-rate characteristics using an isothermal tank instead of a flow meter. However, this method measures only the decreasing flow rate part of the hysteresis curve of forward flow and relief flow characteristics.

NOTE       The tests related to electro-pneumatic pressure control valves are specified in ISO 100942.
