ASTM D1403 Cone Penetration of Lubricating Grease using one-quarter and one-half scale Equipment
This test is intended to give the same information as ASTM D217 Cone Penetration of Lubricating Grease, using a smaller sample size. Although less precise than ASTM D217, this method is intended for use when only a small amount of sample is available. Depending on the quantity of sample available, the cone may be either one-half scale (50 grams of sample) or one-quarter scale (10 grams of sample). This test measures the depth, in tenths of a millimeter, to which a one-half scale or a one-quarter scale standard cone will sink when allowed to fall according to the method. The predicted full scale penetration value is calculated and reported.
When requesting this test, please let us know if you wish a one-quarter scale or a one-half scale cone, and a worked or unworked penetration. Also please let us know if you wish any deviations from the ASTM method, such as a temperature other than 25ºC.
