ASTM D6547 Standard Test Method for Corrosiveness of Lubricating Fluid to Bimetallic Couple
9. Report
9.1 Report the following information:
9.1.1 Report the fluid as failing the test if the test areas of more than one disk show signs of corrosion, pitting, or other attack. Also report the fluid as failing if two disks are free of corrosion, but the third shows more than three affected spots.
9.1.1.1 Wipe the dish with a lint-free cloth. Rate the specimen as passing if no discoloration or pitting is visible.
9.1.2 Report the fluid as passing ifthe condition of the disks is other than these.
10. Precision and Bias
10.1 Precision - It is not practical to specify the precision of the procedure in this test method because the results ofthis test method are only intended to give a pass/fail rating to the fluid being tested.
10.2 Bias - The procedure in this test method has no bias because the value of corrosion-preventing characteristics is defined only in terms of this test method.
