GB/T 7326-1987 — This standard applies to the determination of copper corrosion grease. The forecast standard lubricating components (such as copper or a copper alloy containing some of the bearing) with a possible chemical etching significance.
Such corrosion may cause premature bearing damage. But with the actual use, is generally considered the most dynamic running is no correlation between the lubricated components.
This standard does not apply grease capacity measured in addition to itself, and grease caused by other factors for copper corrosion inhibition.
