Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 corrosionthe chemical or electrochemical reactionbetween a material, usually a metal, and its environment thatproduces a deterioration of the material and its properties.3.1.1.1
9、DiscussionIn this test method, corrosion is mani-fested by red rust or black stains on the bearing race. Stains,through which the underlying metal surface is still visible, arenot considered corrosion in Test Method D 5969 and shall beignored. D 17434. Summary of Test Method4.1 New, cleaned, and lub
