Abstract
Counting solid particles in oil is one important indicator of machine condition. ISO 11171-1999 provides a vehicle for objective particle counter performance verification since most important instrument parameters are measured and verified. Most importantly the standard sets values to be met for acceptable instrument performance.
It is the complexity of these test procedures, which make it difficult to implement this standard. Manufacturers certify that their instrument meet ISO 11171 requirements but stop short of providing detailed documentation. ISO 11171 results of five different models instruments are presented. Only one of the five instruments passed all ISO 11171 performance criteria.
