Petroleum products and lubricants - Determination of rust-prevention characteristics of lubricating greases - Part 1 : dynamic wet conditions
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.

Petroleum products and lubricants - Determination of rust-prevention characteristics of lubricating greases - Part 2: Method with water wash-out
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.

Green Design Product Evaluation Technical Specifications for Pesticide Formulations and Waterborne Architectural Coatings (2020)
1.1 This test method covers the laboratory determination of the viscosity of engine oils at 150 °C and 1.0·106 s−1 using a viscometer having a slightly tapered rotor and stator called the Tapered Bearing Simulator (TBS) Viscometer.2 1.2 The Newtonian calibration oils used to establish this test method range from approximately 1.2 mPa·s to 7.7 mPa·s at 150 °C. The precision has only been determined for the viscosity range 1.47 mPa·s to 5.09 mPa·s at 150 °C for the materials listed in the precision section. 1.3 The non-Newtonian reference oil used to establish the shear rate of 1.0·106 s−1 for this test method has a viscosity closely held to 3.55 mPa·s at 150 °C by using the absolute viscometry of the TBS. 1.4 Manual, semi-automated, and fully automated TBS viscometers were used in developing the precision statement for this test method. 1.5 Application to petroleum products such as base oils and formulated engine oils was determined in preparing the viscometric information for this test method. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6.1 This test method uses the milliPascal·second (mPa·s) as the unit of viscosity. This unit is equivalent to the centipoise (cP). 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides a
