Viscosity Tubes* TIME-TEST VISCOSITY TUBES, 10.65mm

Cargille Viscosity Tubes are divided into four Classes as determined by precision sorting in accordance with bore size, number of score marks and contemplated method of use for bubble rise testing. The numbers assigned refer to bore size, which is expressed in mm. TIME-TEST VISCOSITY TUBES, 10.65mm Time-Test Viscosity Tubes are frequently referred to as ASTM D-1545 Tubes, which originated from the adopted standard method of test for viscosity as described in ASTM D-1545* issued by the American Society for Testing and Materials. Time-Test Tubes are scored in three places, 27mm, 100mm and 108mm. The score mark at 27mm is used for a 73mm timed bubble travel. Time-Test Viscosity Tubes are also subjected to additional testing procedures to ascertain the 10.65mm bore which is very critical for precision measuring. CLASS : Time-Test, 10.65mm ( ASTM D-1545) SCORE MARKS : 108mm, 100mm, 27mm I.D. + / -0.025mm : 10.65 METHOD OF TESTING : Bubble time rise or bubble comparisons
