Impact of changes in ISO fluid power particle counting. Contamination control and filter test standards1 Scope This Technical Report discusses the impact of changes in International Standards for particle counting, contamination control, and filter testing. Liquid automatic particle counters (APCs) are used in monitoring contamination levels in hydraulic fluids, to establish component and assembly cleanliness level specifications, and in determining filter efficiencies and particle size ratings. As a result of the replacement of ISO 4402 with ISO 11171

NOTE: BS EN 1709 does not apply to cableway installations for the transportation of goods or to lifts

transport and storage of materials to be tested and preparation of test specimens are specified in BS ISO 16000-11

and after prescribed tests to determine probable maintained performance in service

BS ISO/IEC 19796-3 extends the “reference framework for the description of quality approaches” (RFDQ) defined in BS ISO/IEC 19796-1

differential measurements

establish a strong foundation for decision making and encourage proactive management in all areas

and in particular for maintenance of accuracy up to several times the rated current

It has been superseded by the recently published EN ISO 25539-1:2009 Cardiovascular implants
