Flow Cup Viscosity 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.

Flow cup viscosity standards.

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. This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes cst using a viscosity calculator. 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.

Cannon flow cup viscosity standards are for use in zahn shell and ford flow cups. Find detailed technical data for all paragon flow cup viscosity standards on the paragon scientific webpage. Certified according to iso 17025 iso 17034 under ukas accreditation. The process of flow through an orifice can often be used as a relative measurement and classification of viscosity.

A high density material will flow from a cup in a shorter time than a low density material of the same viscosity. Density g ml in accordance with astm d1480. Excess fluid is collected in the gutter channel. Shown in the graph is the viscosity cup number and the standard g series oil used for its calibration.

Brookfield viscosity standards are used to check the calibration of your instrument. Viscosity cups consist of a hollow cylinder which terminate in a nozzle in the bottom. Manufactured in accordance with astm d 2162 the primary method for viscosity. Certified at 20 c and 25 c each value is tested to astm d 2162 for viscosity measurement and astm d 1480 for density.

Data is also provided at 20 c and 23 c. Nominal values at 25 c are shown in the associated table. Each cup design is unique and care must be taken when comparing viscosity values between different cup types. 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.

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. Lot specific kinematic viscosity data in mm s cst and calculated cup drain times are provided with each standard. It has been constructed from the various international standard calculators.
