U.S. Technical Advisory Group for Contamination Control Convenes in Memphis

fluid power standardization

The U.S. Technical Advisory Group (TAG) to Subcommittee 6 – Contamination Control recently met in Memphis, Tennessee. Twenty-nine committee members came together to continue work on contamination-related standards, focusing on deliverables for the upcoming TC 131/SC6 meetings in Xinxiang, China, where three representatives from the U.S. TAG will meet with worldwide engineering counterparts.

Two major ongoing projects discussed include:

ISO 11171, Calibration of automatic particle counters for liquids: Ballot results were discussed as were editorial comments. The project is currently on a 48-month schedule. Material analysis of samples is ongoing and available findings will be discussed at the fall ISO meeting to determine appropriate next steps.

ISO 4405, Determination of particulate contamination level by the gravimetric method: This standard has not been updated since 1991. The objective of the study was to demonstrate a U.S. best practice to ISO-counterparts for inclusion in a possible ISO 4405 update. The TAG is in the process of drafting new technical procedures that can be incorporated into the ISO 4405 standard. The findings will be circulated during the October ISO meetings to the broader ISO fluid power community.

The U.S. TAG on contamination control meets three times per year. If you would like to get involved in the U.S. ISO Standards development process, please contact Denise Husenica at dhusenica@nfpa.com.
