ISO - 19973-5

Pneumatic fluid power - Assessment of component reliability by testing - Part 5: Non-return valves, shuttle valves, dual pressure valves (AND function), oneway adjustable flow control valves, quick-exhaust valves

active, Most Current
Organization: ISO
Publication Date: 1 September 2015
Status: active
Page Count: 26
ICS Code (Fluid power systems in general): 23.100.01
scope:

This part of ISO 19973 provides test procedures for assessing the reliability of the following types of pneumatic valves:

- non-return (check) valves;

- pilot-operated non-return valves;

- shuttle valves;

- dual pressure valves (AND function);

- one-way adjustable flow control valves;

- quick-exhaust valves

by testing and the methods of reporting the results of testing. General test conditions and the calculation method are provided in ISO 19973-1. The methods specified in ISO 19973-1 apply to the first failure, as obtained with the three-points moving average (3PMA) method, without repairs, but excluding outliers.

The lifetime of these pneumatic valves is usually given as a number of cycles. Therefore, whenever the term "time" is used in this part of ISO 19973, this variable is understood as a number of cycles.

This part of ISO 19973 also specifies test equipment and threshold levels for tests to assess the reliability of these pneumatic valves.
