Along with performing systematic reviews on existing fluid power related ISO Standards, The U. S. Technical Advisory Group (TAG) has been working on a number of ISO draft International Standards projects related to contamination control, pneumatic control products and sealing devices:
ISO 21018-4 – Hydraulic fluid power — Monitoring the level of particulate contamination in the fluid — Part 4: Use of the light extinction technique is part of the 21018 series of Standards that standardizes operating procedures for automatic particle counters and monitors. Part 4 of this ISO 21018 defines procedures for the use of light extinction instruments in evaluating the cleanliness level of a hydraulic liquid. It also includes procedures for calibrating and verifying that the instruments are operating correctly to ensure consistent results.
ISO 11727 – Pneumatic fluid power — Identification of ports and control mechanisms of control valves and other components includes rules for identifying and marking the ports and the control mechanisms permitting the user to properly connect components in a system when using a circuit diagram.
ISO 6194-3:2009 – Rotary shaft lip-type seals incorporating elastomeric sealing elements — Part 3: Storage, handling and installation which is part of the ISO 6194 series that describes seals utilizing elastomeric sealing elements suitable for use under low-pressure conditions. This part of ISO 6194 gives users of lip-type seals requirements and guidance on the careful storage, handling and proper installation of rotary shaft lip-type seals; attention is drawn to the hazards involved and ways of avoiding them.
To learn about NFPA and ISO Standards (draft, published, or withdrawn) relevant to fluid power go to NFPA’s Standards Locator.
For more information on NFPA’s involvement on the development Standards, please contact Denise Rockhill.
This holiday season, we are thankful for each of our members. All your staff at NFPA want to thank you for all of the efforts that you have put in to help grow the fluid power industry. We couldn’t fulfill our mission without your dedication and support. Enjoy this time off with your loved ones,…
Doug is the Application Engineering Supervisor for HAWE North America, a manufacturer of hydraulic power units, pumps, valves and cylinders. HAWE will be showcasing their water resistant hydraulics that help deliver power to speed boats at IFPE – the International Fluid Power Exposition — and we invited Doug into our forum to learn more about…
