WebEMCOR RUST TEST. The purpose of the Emcor rust test is to measure the ability of grease to protect a bearing against corrosion even in the presence of water. During the Emcor test, bearings are lubricated with a mixture of grease and distilled water. At the end of the test, a value between 0 (no corrosion) and 5 (very severe corrosion) is given. WebOfficially, hardness testing loads are expressed in Newton (N). However, historically, loads were expressed in kilogram-force (kgf), gram-force (gf), or pond (p). The correlation between kgf, kp, and N is: 1.0 kgf = 1,000 gf = 1.0 kp = 9.81 N. The term micro hardness testing is usually used when indentation loads are below or equal to 1 kgf.
