The test parameters for performance fluids are categorized into the three components of the TriVector™. Wear parameters indicate the sources of mechanical breakdown within the equipment itself.  Chemistry indicates the condition of the performance fluid itself.  Contamination parameters indicate the source and level of foreign substance ingress.
