Means of Assessing Aviation Turbine Lubricant Quality 660074
There is no single and easy way of measuring turbine lubricant quality.
Various methods and tests are used but it is only by a thorough analysis of operation, maintenance and the overall performance achieved under a multiplicity of conditions that the quality can be objectively assessed. Unless this approach is followed, the assessment of quality tends to be based solely on compliance to specifications with their limitations and engine or equipment inspection ratings with their inherent subjective factors.
Assessment of a lubricant's quality is also a continuing process. It is, in fact, a matter of endeavoring to determine its ultimate limitations.
