In recent years, I’ve been part of numerous investigations relating to expensive machine failures preceded by oil samples that registered high particle counts. Each time I asked the asset owner, my...
OEMs rarely include specific cleanliness requirements for components in operation. When they do, the recommendation is usually less than aggressive, to say the least. So why is cleanliness so important? Haven’t operations been taking place since the beginning of the industrial revolution without specific cleanliness standards in place? Why are such controlled operating parameters required today?
The ability to trend and evaluate data is essential in the proper use of oil analysis technology. By definition, the term “trend” means to show a tendency. Typically this means either a...
