New ISO Standard (ISO 19973-4:2014) Now Available from NFPA

A new ISO Standard has recently been published and is now available from the National Fluid Power Association (NFPA).

PRLog - April 21, 2014 - MILWAUKEE -- ISO 19973-4:2014, Pneumatic fluid power – Assessment of component reliability by testing – Part 4: Pressure regulators [second edition]. ISO 19973-4:2014 provides test procedures for assessing the reliability of pneumatic pressure regulators by testing, using the general test conditions and calculation method from ISO 19973-1. ISO 19973-4 applies to manually adjustable and remote-piloted pressure regulators, both relieving and non-relieving, but does not apply to pressure regulators that have a permanent bleed. The standard also specifies test equipment and failure criteria (threshold levels) for tests to assess the reliability of pneumatic pressure regulators.

ISO 19973-4 benefits users of pneumatic components by providing a standardized method for assessing and expressing the reliability of pneumatic pressure regulators. This allows users to determine if a particular component is suitable for the application and to compare the reliability of components from different manufacturers.
