DIN 51350-6 Shear Stability Of Lubricating Oils Containing Polymers

KN-51350-6 Apparatus for Shear Stability of Lubricating Oils Containing Polymers

Overview

KN-51350-6 Apparatus for Shear Stability of Lubricating Oils Containing Polymers conforms to DIN 51350-6. Testing of lubricants - Testing in the Shell four-ball tester - Part 6: Determination of shear stability of lubricating oils containing polymers. The apparatus is used for the determination of the shear stability in the Shell four-ball tester of lubricating oils containing polymers.

The tapered roller shearing system is a system for assessing the viscosity shear stability of a transmission lubricant. The equipment is a standard four-ball extrusion tester with a constant temperature device. Its composition consists of: embedded body, mandrel, tapered roller friction pair, tapered roller bearing, and temperature control instrument.

The tapered roller bearing tester (KRL) is a mechanical shear stress caused by the lubricating oil under the test conditions similar to the gearbox, resulting in permanent viscosity loss and movement according to the test lubricant before and after the test. The rate of decrease in viscosity is indicative of the shear stability of the lubricating oil. This test method evolved from the sixth part of the German standard DIN 51350, also known as KRL (German Kugel Rollen Lager abbreviated) or CEC L-45-99.
