The U. S. Technical Advisory Group (U.S. TAG) to ISO/TC 131 provides input and promotes U.S. interests in the development of the International Standards Organization (ISO) standards for fluid power products and systems. NFPA administers the U.S. TAG on behalf of the American National Standards Institute (ANSI). The membership of the U.S. TAG is made up of more than 150 participants from more than 80 U.S. companies, universities, government, technical societies and trade associations.
The U.S. TAG to ISO/TC 131/SC 6 develops USA industry’s input on ISO standards for contamination control. Examples of topics covered are calibration of automatic particle counters, filter multipass test and methods for determining the cleanliness of components. NFPA welcomes four new committee members to SC 6:
- Bill Bars with Beckman Coulter Life Services
- Kenneth Nicholas, Donaldson Company, Inc.
- Nick Stanley, Donaldson Company, Inc.
- Peter Rao U.S. Army, RDECOM
The U.S. TAG to ISO/TC 131/SC 6 meets three times per year. Current projects underway include:
| ISO/DIS 18413 – Hydraulic component cleanliness inspection document and principles related to contaminant collection, analysis and data reporting (revision of ISO 18413:2002) |
| ISO/WD 23309 – Methods of cleaning lines in an assembled hydraulic system by flushing [revision of ISO 23309:2007] |
| ISO/WD 12669 – Method for determining the required cleanliness level [RCL] for a hydraulic system |
| ISO/DIS 16908 – Hydraulic filter element thermal conditioning and cold start-up simulation |
| ISO/NP – 18237 – Method for evaluating water separation performance of hydraulic fluid dehydrators |
| ISO/CD – Verification of fatigue life and burst pressure ratings of hydraulic spin-on filters with finite lives |
| ISO/NP 3968 – Evaluation of differential pressure versus flow characteristics of hydraulic filters [proposed revision of ISO 3968:2001] |
| ISO/CD 21018-4 – Light extinction technique for monitoring the level of particulate contamination in hydraulic fluids |
| ISO/DTR 16386 – Impact of changes in ISO particle counting, contamination control and hydraulic filter test standards [revision of ISO/TR 16386:1999] |
