These specifications cover some widely used glass capillary viscometers suitable for use in accordance with test methods ASTM D, IP 71 and ISO to determine the kinematic viscosity of petroleum liquids.

Please contact our sales team sales tamson. Viscosity standards used to calibrate the glass capillary viscometers are ISO dual certified for both viscosity and density. All glass capillary viscometers are delivered with a calibration certificate.

These specifications in ASTM D, ISOIP 71, and BS cover operating instructions for glass capillary kinematic viscometers of all the types described in detail for modified Ostwald viscometers, suspended-level viscometers and reverse-flow viscometers. This is not the case.

Without these strict specifications and operating instructions it will be impossible to meet the precision requirements for the kinematic viscosity determination mentioned in test methods ASTM D, IP 71 and ISO In addition to increased bath space, full length viscometer tubes require more solvent to clean their larger surface area. Does D require use of a full length capillary tube?
