Flow Cup Viscosity Standards

Viscosity cups consist of a hollow cylinder which terminate in a nozzle in the bottom.
Flow cup viscosity standards. Shown in the graph is the viscosity cup number and the standard g series oil used for its calibration. Data is also provided at 20 c and 23 c. It has been constructed from the various international standard calculators. Nominal values at 25 c are shown in the associated table.
Manufactured in accordance with astm d 2162 the primary method for viscosity. The process of flow through an orifice can often be used as a relative measurement and classification of viscosity. Excess fluid is collected in the gutter channel. Brookfield viscosity standards are used to check the calibration of your instrument.
Flow cup viscosity standards features fungilab iso 17025 iso guide 34 dual certified flow cup standards are especially designed for use in din ford iso shell and zahn flow cups and are also dual purpose density standards. Certified at 20 c and 25 c each value is tested to astm d 2162 for viscosity measurement and astm d 1480 for density. Find detailed technical data for all paragon flow cup viscosity standards on the paragon scientific webpage. Each cup design is unique and care must be taken when comparing viscosity values between different cup types.
Paragon iso iec 17025 and iso 17034 iso guide 34 certified flow cup viscosity standards are specifcally formulated for use with viscosity flow cups such as ford shell zahn. The table below lists the major flow cup types together with a conversion chart of efflux time in seconds to viscosity in centistokes cst. The viscosity is established in terms of the time in seconds in which a precisely controlled volume of fluid flows out through a nozzle of the viscosity cup. A high density material will flow from a cup in a shorter time than a low density material of the same viscosity.
Elcometer offers the option to order viscosity flow cups complete with calibration certificates which offer traceability and assurance that the viscosity cups have been individually tested and comply to standards. Paragon iso 17025 iso guide 34 certified flow cup viscosity standards are specifcally formulated for use with viscosity flow cups such as ford shell zahn. Lot specific kinematic viscosity data in mm s cst and calculated cup drain times are provided with each standard. However gravity is the driving force causing liquid in a viscosity cup to flow through the orifice.
Certified according to iso 17025 iso 17034 under ukas accreditation. Density g ml in accordance with astm d1480. The flow cups can be supplied separately or with an adjustable stand which includes a precision level and an overflow glass draw plate.
