Standards Development Activity for January 2015

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 21018-4Hydraulic 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 11727Pneumatic 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 6194-3:2009Rotary 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To learn about NFPA and ISO Standards (draft, published, or withdrawn) relevant to fluid power go to NFPA’s Standards Locator.
