Fluid Power Engineers Represent U.S. at ISO Technical Committee Meetings in Poland

Fluid power experts from around the globe recently gathered at the University of Science and Technology in Wrocław, Poland. They discussed fluid power related ISO standard issues in the following subcommittees and working groups:

• Fluid power terms and symbols
• Sealing devices
• Product testing
• Control products (valves)
• Pneumatic systems
• Reliability of pneumatic components

Twenty-seven engineering experts representing Poland, Germany, France, Turkey, Italy, United Kingdom and the United States attended.  Committee members included engineers from FESTO, SMC, Parker Hannifin, ARTEMA, Asco Numatics, CETIM, Bosch Rexroth, and Eaton.  (Thank you to the U.S. delegates from Parker Hannifin, Polymod Technologies, Purdue University, and SMC Corporation for your contributions around the discussion tables.)  The delegates worked hard to answer outstanding questions related to individual ISO projects to approve or revise the standards needing updates. Some of the projects underway include:

Revision of ISO 5598:1985, Fluid power systems – Vocabulary. This document provides users with pertinent terms that have specific meanings in fluid power technology. The working group continued its work on adding new and revising current definitions for fluid power systems and components.

New Work Item Proposal – Hydraulic fluid power – Methods for calculating application-duty cycle based performance indices for hydraulic pump.  This project was not accepted as proposed by the U.S.  The project leader was asked for a new work item proposal starting with one component (hydraulic pump) cycle using a mathematical model and real values.

Possible new work on measurement of minimum shifting/operating pressure of pneumatic valves – The U.S. project leader continued the discussion on his proposal for Minimum Shift Pressure Test of Pneumatic Valves.  He recommended that a round robin test was in order to gather more data, and it was agreed upon.

 
Thank you to the University of Science and Technology, and the beautiful city of Wrocław, for welcoming the ISO/TC 131 and its subcommittees and working groups to the 2016 spring meeting cluster.  The next ISO/TC 131 meeting cluster is scheduled for October 2016.  NFPA member companies are encouraged to participate in standards development for the fluid power industry.  Click here to learn how you can get involved.
