Ford cup
Ford Cups is an instrument to determine the viscosity of Newtonian or near- Newtonian paints, varnishes, and related liquid materials. The Ford Cups is filled level full with the liquid under test, and the time for the material to flow through one of the standard orifices is measured. This test method is useful for the determination of package and application viscosities of a number of paints and other coatings and in the thinning of these materials, but is limited the Newtonian or near- Newtonian liquids. A cup can produce satisfying and reproducible results when used within its defined viscosity range. Ford Cups is not suitable for measuring high viscosity liquids, pastes, etc.
Ford Cups produced by our company is in accordance with specification of ASTM D1200. Ford Cups is made of corrosion-and solvent-resistant material, material of Ford Cup Body is aluminium alloy, material of Ford Cup Orifice is brass, which is subject to wear with use and cleaning. We adopts similar ISO Flow Cup model, different from ASTM D1200 recommended model, it is easily cleaned & more firmly placed. Each single cup is calibrated against standard oil in a factory. If orifice is loosened or taken out from a cup, the cup should be recalibrated.
The following formulas are used to convert the time of flow in seconds, t, to kinematic viscosity V:
Ford Cup No.2 V=1.44(t-18)
Ford Cup No.3 V=2.31(t-6.58)
Ford Cup No.4 V=3.85(t-4.49)
Ford Cup No.5 V=12.1(t-2)
