ISO/TC 28/WG 19 - Development of test methods and field performance equipment for greases

This document specifies a method for evaluating the resistance of a lubricating grease to washout by water from a bearing, when tested at 38 °C or 79 °C under specified laboratory test conditions. This test method estimates the resistance of greases to washout from ball bearings under specified conditions. No formal correlation with field service has been established so far. This document is used for development and specification purposes. NOTE For the purposes of this document, the term “% (m/m)” is used to represent the mass fraction.

This document specifies a method for the determination of the rust prevention characteristics of lubricating grease under dynamic wet conditions. This test method is used to assess the ability of a grease to prevent corrosion in rolling bearings operated in presence of water, synthetic sea water or any industrial aqueous pollutant. NOTE For the purposes of this document, the term “% (m/m)” is used to represent the mass fraction.

This document specifies several methods for the empirical estimation of the consistency of lubricating greases and petrolatum by measuring the penetration of a standardized cone.

This document specifies methods for obtaining samples of lubricating grease from production lots or shipments and gives instructions for inspecting greases in sales packages.

This document specifies a method for measuring the quantity of oil separated from lubricating grease in the test conditions. It can be used to predict the behaviour of greases on storage in pails and drums. This method is not applicable to very soft greases that, during the test, flow unchanged through the sieve.

This document specifies a method for the determination of the dropping point of lubricating grease using an automatic apparatus.

This document specifies a method for the determination of the rust prevention characteristics of lubricating grease in the presence of a flow of an aqueous test fluid. This test method is used to assess the ability of a grease to prevent corrosion in rolling bearings operated in presence of water, synthetic sea water or any industrial aqueous pollutant, under wash out conditions. NOTE For the purposes of this document, the term “% (m/m)” is used to represent the mass fraction.
