It has been constructed from the various international standard calculators.
Flow cup viscosity standards.
This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes cst using a viscosity calculator.
Certified at 20 c and 25 c each value is tested to astm d 2162 for viscosity measurement and astm d 1480 for density.
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.
Each cup design is unique and care must be taken when comparing viscosity values between different cup types.
The flow cups can be supplied separately or with an adjustable stand which includes a precision level and an overflow glass draw plate.
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.
Flow cups are designed to accurately measure the viscosity of paints inks varnishes and similar products.
Excess fluid is collected in the gutter channel.
Manufactured in accordance with astm d 2162 the primary method for viscosity.
Lot specific kinematic viscosity data in mm s cst and calculated cup drain times are provided with each standard.
Cannon flow cup viscosity standards are for use in zahn shell and ford flow cups.
Nominal values at 25 c are shown in the associated table.
Data is also provided at 20 c and 23 c.
Brookfield viscosity standards are used to check the calibration of your instrument.
Density g ml in accordance with astm d1480.
Find detailed technical data for all paragon flow cup viscosity standards on the paragon scientific webpage.
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.
A high density material will flow from a cup in a shorter time than a low density material of the same viscosity.
Viscosity cups consist of a hollow cylinder which terminate in a nozzle in the bottom.
However gravity is the driving force causing liquid in a viscosity cup to flow through the orifice.
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.
Shown in the graph is the viscosity cup number and the standard g series oil used for its calibration.
The process of flow through an orifice can often be used as a relative measurement and classification of viscosity.
