Special Sampling Considerations
Follow up on abnormal samples IND 3 WearCheck advises that ferrographic analysis be performed with resamples on equipment that tested abnormal. Filter analysis allows the diagnostician to locate and detect major wear situations.
Extended oil drain intervals IND 2 Any equipment that is undergoing extended oil drain interval testing should use IND 2 test kits. These kits include TAN testing to monitor the degradation of the oil, as well as the build up of acids in the oil. Oils with high TAN levels generally experience oil thickening, sludging, improper oil flow, and corrosion of components.
Critical Systems IND 3 IND 3 kits include the most comprehensive battery of tests to monitor the oil condition, wear condition, and contamination levels of the system.
