BS ISO 6953-2:2015

1   Scope This part of ISO 6953 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 ISO 6953-1. The purpose of this part of ISO 6953 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 [ISO 10094](/search?q=ISO%C2%A010094)−2. 


 
   NOTE 2  Use [ISO 6953-3](/search?q=ISO%C2%A06953-3) 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.
