Describes the test procedures and a method of presenting the results concerning the parameters which define the main characteristics to be included in the supplier's literature of the electro-pneumatic continuous pressure control valves.

This part of ISO10094 specifies the test procedures and a method of presenting the results concerning the parameters which define the main characteristics to be included in the supplier\'s literature of the electro-pneumatic continuous pressure control valves, conforming to ISO10094-1.

The purpose of this part of ISO10094 is

• to facilitate the comparison by standardizing the test methods and the presentation of the test results, and

• to assist in the proper application of these components in compressed air systems.

The specified tests are intended to allow comparison between the different types of continuous pressure control valves; these are not production tests to be carried out on each manufactured product.

NOTE1 The tests related to non-electrically modulated pneumatic continuous pressure control valves are specified in ISO6953-2.

NOTE2 The tests related to electro-pneumatic continuous flow control valves are specified in ISO10041-2.

NOTE3 The tests described in this part of ISO10094 are realised on components with an exhaust port vented to the atmosphere.
