SAE AIR5455 - IMPACT OF CHANGES IN TEST DUST CONTAMINANTS AND PARTICLE COUNTER CALIBRATION ON LABORATORY FILTER ELEMENT PERFORMANCE AND FLUID CLEANLINESS CLASSES Organization: SAE
Date: 2012-01-01
Description: In addition, ISO has also instituted a new calibration procedure, ISO 11171, for automatic particle counters (APCs) utilized in filter performance testing and measuring fluid cleanliness levels as a replacement for the previous calibration procedure ISO 4402 (1991) which utilized AC Fine Test Dust. This information report compares and contrasts laboratory filter element performance and fluid cleanliness levels obtained with the new test dusts and ISO 11171 calibration procedure to those obtained with the AC Test Dusts and the previous calibration procedure ISO 4402 (1991).
