The U.S. Technical Advisory Groups (TAGs) for contamination control (TC 131/SC 6), connectors (TC 131/SC 4) and terms and symbols (SC 1/WG 2) met recently to continue the ISO standardization work in fluid power systems. More than 30 NFPA TAG and SAE connector and filter test engineering experts attended in-person or virtually. Both NFPA and non-NFPA members, representing many fluid power-related companies, were in attendance, including SMC, H&V, Lydall, Donaldson, Pall, Parker, Cummins, Eaton, Danfoss, Caterpillar and Holmbury.
In the international arena, the U.S. TAG develops and advocates for the U.S. position in fluid power standards. Here is a sample of the projects currently under development:
- ISO 11171, Calibration of automatic particle counters for liquids.
Discussions continue between the international experts on the best possible path forward to publish an updated document taking into consideration the new and future SRM2806d test fluids currently being developed by NIST. A technical report will also be published to explain the methodology behind the updates needed in ISO 11171.
- ISO 6162-1:2012 [Hydraulic fluid power — Flange connections with split or one-piece flange clamps and metric or inch screws — Part 1: Flange connectors, ports, and mounting surfaces for use at pressures of 3,5 MPa (35 bar) to 35 MPa (350 bar), DN 13 to DN 127]
Discussion continues in a taskforce of U. S. and German experts on suggested future drawing and material changes.
- ISO 5598, Fluid power systems and components – Vocabulary.
Work has begun to update the document with additional terms and definitions.
The next U.S. TAG to TC 131/SC 6 and TC 131/SC 4 meetings will be held in a hybrid format in the March/April timeframe. Other U.S. TAGs continue to meet virtually as needed. If you are interested in attending and/or participating in standards development, please contact Denise Husenica at firstname.lastname@example.org.
The National Fluid Power Association (NFPA) has entered into a partnership agreement with UKI Media & Events to convene and co-locate an advanced hydraulics conference for off-highway vehicle and fluid power engineers at iVT EXPO, to be held August 21-22, 2024, in Chicago, IL. iVT EXPO is an annual exposition for the off-highway vehicle design…
There is still time to register for April’s Fluid Power Vehicle Challenge Final Competitions. We need industry attendees to judge all aspects of the final competitions: the races, final presentations and vehicle design reviews. Industry attendees also participate in exclusive networking opportunities to recruit the next generation of talented engineers. Please register by March 1st.…
A new series of quarterly forecast updates from Oxford Economics is now available on the NFPA website at Global Industry Forecasts. These reports cover the global economy, as well as regional and country developments, and some detailed global industry forecasts. Oxford predicts a slow first half of 2024 with US industrial output being particularly stagnate.…
