Method of test for petroleum and its products - BS 2000-527: Petroleum products and lubricants - Determination of low-temperature cone penetration of lubricating greases
This International Standard specifies a method for determining the cone penetration of lubricating greases at low temperatures. NOTE 1 Precision has only been determined in the temperature range -40 ℃ to -20 ℃. This International Standard may be used at other temperatures, e.g. -20 ℃ to +20 ℃, however precision has not been determined under these conditions. NOTE 2 The cone penetration is expressed in units of 0,1 mm.
