Grease, Wax And Bitumen Testing Apparatus

Softening Point Apparatus test is a test at temperature bitumen disk is soften & sag downward at specific distance mounted on shoulder rings & heated at controlled rate under the weight of steel ball.

Drop Point Apparatus is a numerical value assigned to a grease composition representing the temperature at which the first drop of material falls from the test cup that temperature being the average of the thermometer readings of the sample and bath. This test method covers the determination of the dropping point of lubricating grease.

This test method covers determination of the penetration of semi-solid and solid bituminous materials to determine consistency & shear stability for design quality control and identification purposes A standard cone or needle is released from penetrometer and allowed to drop freely into the sample for 5 seconds The depth of penetration of the cone or needle into the sample is measured in tenths of a millimetre by the penetrometer.
