16 reviewed editorial explainers connecting laboratory measurements to programme design, representative sampling, field decisions, limitations and verified next steps.
The analytical result describes the submitted portion. The sampling system determines whether that portion describes the asset, tank or fluid population you intended to assess.
Read technical note →Absolute thresholds are one decision tool. Rate of change, correlated signals, sampling comparability and asset criticality can reveal a developing condition earlier.
Read technical note →Elemental concentration, bulk ferromagnetic response and particle morphology are complementary views of a wear-debris population—not interchangeable measures.
Read technical note →Recurrent filter blockage is an observation with several possible mechanisms. Tank-layer sampling and examination of the retained material narrow the investigation.
Read technical note →Dye is not a controlled universal code for glycol type, inhibitor technology, concentration or equipment approval.
Read technical note →Diagnostic gases support hypotheses about electrical and thermal activity. Sampling integrity, generation rate, operating context and companion evidence determine confidence.
Read technical note →A useful panel covers fluid condition, contamination and machine wear at a depth justified by the asset, failure mechanisms and maintenance decision.
Read technical note →Severity classes organise attention. They become reliable only when the sample, trend, operating context, corroborating evidence and maintenance feedback are considered together.
Read technical note →A primary point trends the whole circulating system. Secondary points localise a component source or evaluate a filter, cooler or treatment stage.
Read technical note →Identification, operating context, collection, preservation, transport and feedback can each change the usefulness of an otherwise accurate laboratory result.
Read technical note →Fine-element spectroscopy, ferrous density, particle counting, microscopy and filter debris overlap—but no single method sees the complete wear population.
Read technical note →Incoming-fluid identity, cleanliness, water control and storage handling should be verified before the material becomes the machine’s new baseline.
Read technical note →Grease is semi-solid, heterogeneous and often available only in small quantities. Location, purge history and sample handling strongly influence the result.
Read technical note →Oil carries evidence from lubricated surfaces and fluid chemistry. Other condition-monitoring technologies observe motion, heat, sound and physical condition.
Read technical note →Extending or shortening a drain interval should be a controlled reliability decision—not a reaction to one viscosity, acid or base-number result.
Read technical note →A high sample count does not prove value. Data quality, alert response, confirmed findings and verified corrective action show whether the programme changes risk.
Read technical note →These sources informed topic selection and coverage gaps. The Wiki uses original editorial wording, cites the relevant pages and continues to use official standards bodies for method and conformity decisions.
