  • ASTM D445 method for kinematic viscosity of transparent and opaque liquids 4. Summary of Test Method4.1 The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature. The kinematic viscosity (determined value) is the product of the measured ...
  • ASTM D445 method for kinematic viscosity of transparent and opaque liquids 3. Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 automated viscometer, n-apparatus which, in part or in whole, has mechanized one or more of the procedural steps indicated in Section 11 or 12 without changing the principle or technique of the basic manual apparatus. The essential ...

  • ASTM D445 method for kinematic viscosity of transparent and opaque liquids 1. Scope1.1 This test method specifies a procedure for the determination of the kinematic viscosity, v, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, ...
  • ASTM D566 standard test method for dropping point of lubricating grease 10. Report10.1 Report the result to the nearest degree as the ASTM-IP dropping point, ASTM D566.11. Precision and Bias11.1 Precision - The precision of this test method as determined by statistical examination of interlaboratory results is as follows:11.1.1 Repeatability - The difference between two ...
  • ASTM D566 standard test method for dropping point of lubricating grease 9. Procedure9.1 Fill a test cup with sample by pressing the larger opening into the grease to be tested until the cup is filled. Remove excess grease with a spatula. Gently press the cup, held in a vertical position with the smaller opening at the bottom, down over the metal rod until the latter protrudes ...
  • ASTM D566 standard test method for dropping point of lubricating grease 8. Preparation of Apparatus8.1 Thoroughly clean the cup and test tube with mineral spirits conforming to Specification D235. (Warning - Flammable. Vapor harmful.)8.2 Use only cups that are clean and free from any residue from previous runs. When the interior plating of the cup shows indications of wear, ...
  • ASTM D566 standard test method for dropping point of lubricating grease 6. Apparatus6.1 Grease Cup - A chromium-plated brass cup conforming to the dimensions shown in Fig.1.6.2 Test Tube - A test tube of heat-resistant glass, with rim, 100 to 103 mm in length and 11.1 to 12.7 mm in inside diameter provided with three indentations about 19mm from the bottom, equally spaced ...
  • ASTM D566 standard test method for dropping point of lubricating grease 4. Summary of Test Method4.1 A sample of lubricating grease contained in a cup suspended in a test tube is heated in an oil bath at a prescribed rate. The temperature at which material falls from the hole in the bottom of the cup is averaged with the temperature of the oil bath and recorded as the dropping ...
  • ASTM D566 standard test method for dropping point of lubricating grease 1. Scope1.1 This test method covers the determination of the dropping point of lubricating grease.1.2 This test method is not recommended for use at bath temperatures above 288°C. For higher temperatures, Test Method D2265 should be used.1.3 The values stated in SI units are to be regarded as standard. ...
