Reagents and Materials6.1 Purity of Reagents - Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents conform to the specifications of the Committee on Analytical ...
  • ASTM D665 for rust-preventing characteristics Rust-preventing characteristics of inhibited mineral oil in the presence of water5. Apparatus5.1 Oil Bath - A thermostatically controlled liquid bath capable of maintaining the test sample at a temperature of 60 more or less 1°C (140 more or less 2°F) (see Note 4). An oil having a viscosity of approximately ...
  • ASTM D665 for rust-preventing characteristics Rust-preventing characteristics of inhibited mineral oil in the presence of water3. Summary of Test Method3.1 A mixture of 300 mL of the oil under test is stirred with 30 mL of distilled water or synthetic sea water, as required, at a temperature of 60 more or less 1°C (140 more or less 2°F) with a ...
  • ASTM D665 for rust-preventing characteristics Rust-preventing characteristics of inhibited mineral oil in the presence of water1. Scope1.1 This test method covers the evaluation of the ability of inhibited mineral oils, particularly steam-turbine oils, to aid in preventing the rusting of ferrous parts should water become mixed with the oil. This ...
  • ASTM D217 undisturbed penetration Undisturbed penetration is defined as the penetration at 25°C (77°F) of a sample of grease in its container with no disturbance. Typical uses of the undisturbed penetration are: (1) to control the consistency of certain greases during manufacture, and (2) to assess the degree to which a grease develops ...
  • ASTM D217 cone penetration apparatus 1.1 Penetrometer, similar to the instrument illustrated in Fig. 1, designed to measure in tenths of a millimetre the depth to which the standard (or optional) cone falls into the grease. The cone assembly or the table of the penetrometer shall be adjustable to enable accurate placement of the tip of ...
  • ASTM D217 for cone penetration of lubricating grease 12. Report12.1 Report the following information:12.1.1 Unworked Penetration - Report the average value obtained in 11.1.2 as the unworked penetration of the grease under test.12.1.2 Worked Penetration - Report the average value obtained in 11.2.1 as the worked penetration of the grease under test.12.1.3 ...
  • ASTM D217 for cone penetration of lubricating grease 11. Procedure11.1 Unworked Penetration - Place the cup on the penetrometer table, making certain that it cannot teeter. Set the mechanism to hold the cone in the zero position, and adjust the apparatus carefully so that the tip of the cone just touches the surface at the center of the test specimen. ...
  • ASTM D217 for cone penetration of lubricating grease 9. Preparation of Apparatus9.1 Cleaning Penetrometer Cone - Clean the penetrometer cone carefully before each test with a soft cloth or paper wiper. The wiper can be dampened with an appropriate volatile gum-free solvent, when necessary, to remove any grease remaining on the cone. The solvent should ...
  • ASTM D217 for cone penetration of lubricating grease 8. Sampling8.1 Sample Size - Sufficient sample (at least 0.4 kg (1 lb)) for worked and prolonged worked penetrations and 1.2 kg (3 lb) for unworked penetrations expected over 200) to overfill the cup of the standard grease worker is required. If the sample size is insufficient and penetration ranges ...
