Astm d2670 pin and v-block test
Oil glossary |
Astm test method d2670 is for measuring the antiwear properties of liquid lubricants. the load is applied to the jaws and maintained by a toothed wheel. the wear is a function of the number of the tooth which needs to be engaged to keep the load constant for a fixed time.

Astm d5302 sequence ve, английский
Astm test method d 5302, the sequence ve gasoline engine test, has been correlated with vehicles used in stop-and-go service prior to 1988, particularly with regard to sludge and valve train wear.
Asperities, английский
- Microscopic projections on metal surfaces resulting from normal surface-finishing processes. interference between opposing asperities in sliding or rolling applications is a source of friction, and can lead to metal welding and scoring. ideally, the lubricating film between two moving surfaces should be thicker than the combined height of the opposing asperities.
- Microscopic projections on metal surfaces, invisible to the naked eye, that creates peaks and valleys, even after grinding or machining. when two surfaces are in sliding contact, these imperfections cause interference that results in friction; without proper lubrication, wear, scoring or welding will follow.
