ASTM D 7483-08 test determines liquid viscosity
source: printing talk 2009-03-11 printing equipment
The American Society of Testing Materials (ASTM) has developed ASTM D 7483-08, a standard test-method for determining dynamic and kinematic viscosity of liquids by oscillating piston viscometer.
Oscillating piston viscometers allow viscosity measurement and control of a range of fluids, including those that are transparent, translucent and opaque.
The measurement function of the viscometer is automated to reduce measurement errors.
An electromagnetic piston maintains a continuous fresh sample while under test and requires a small sample-volume.
The test method is suitable for petroleum products and lubricants for bearings, gears, compressor cylinders, hydraulic equipment, general chemicals and coatings, where proper viscosity is important for product performance.
Cambridge Viscosity's sensors and viscometer systems conform to ASTM, DIN, JIS and ISO standards, with a range of models designed to meet specific industry and application needs.
Certifications include ATEX Class 1, Div 1, Group C and D, CE, FM, NEMA.
