DIN 51810-1
Testing of lubricants - Testing rheological properties of lubricating greases - Part 1: Determination of shear viscosity by rotational viscosimeter and the system of cone/plate

Title (German)

Prüfung von Schmierstoffen - Prüfung der rheologischen Eigenschaften von Schmierfetten - Teil 1: Bestimmung der Scherviskosität mit dem Rotationsviskosimeter und dem Messsystem Kegel/Platte

Overview

This document has been prepared by Working Committee NA 062-06-52 AA "Schmierfette: Anforderungen und Prüfung" ("Lubricating greases: requirements and testing") at Technical Committee "Mineralöl- und Brennstoffnormung (FAM)" ("Standardization of mineral oils and combustible materials") at DIN Standards Committee Materials Testing (NMP). This document specifies a method for determining the shear viscosity of lubricating greases of NLGI classes 000 to 2 according to DIN 51818 at a constant shear rate after defined pre-shearing with the cone/plate measuring system.
