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

This part of ISO6953 specifies test procedures and a method of presenting the results concerning the parameters which define the main characteristics to be included in literature from suppliers of regulators and filter-regulators conforming to ISO6953-1.

The purpose of this part of ISO6953 is the following:

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

  • to 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 type of regulators and filter-regulators; they are not production tests to be carried out on each pressure regulator or filter-regulator manufactured.

NOTE 1 The tests related to electro-pneumatic pressure control valves are specified in ISO10094−2.

NOTE 2 Use ISO6953-3 for 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.
