Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The table below can help you select the correct consistency for an application. High structural shear stability coupled with a high performance base oil make Mobil 1 Synthetic an outstanding automotive grease. Just as with oil, the amount of water in a grease sample is calculated using the Karl Fischer KF method. To establish the dropping point, a grease sample is warmed in the testing device until liquid drops fall to the bottom of the test tube through an opening in a nipple. It does not match my search. As they age, molecular compounds alter and absorb more infrared light than fresh grease.
Find out how to take the guesswork out of this decision. Extreme pressure EP additives are additives that provide added load carrying capacity under boundary lubrication conditions. High structural shear stability coupled with a high performance base oil make Mobil 1 Synthetic an outstanding automotive grease. If the grease is very soft, the cone penetrates deeply and the penetration value is high. The shade and intensity observed when lubricating grease is viewed under conditions that eliminate Bloom. Therefore, the relubrication intervals and amounts must be adapted to the decreasing additive levels.
Corrosion can be localized e. To measure penetration, a cone of a specific weight is allowed to sink into a grease for five seconds at a standard temperature of 25 degrees C 77 degrees F. The water is channeled into a titration vessel using a hollow needle and nitrogen. An extremely small fiber, barely visible even at maximum magnification of an electron microscope. The lubricating fluid in a grease can be mineral oil derived from petroleum , a synthetic fluid, or a vegetable based fluid.
Also see Appearance and Texture. This reaction produces thickener fibers plus water as a by-product, This reaction is known as saponification. Lubricate both ends of the FWD drive shaft [ High-perform an c e EP l u br ica ti n g grease w i th lithium-saponified [ Zur Schmierung der Lager wird ein [ As temperatures rise, greases behave differently than edible fats.
