ASTM D1200- Standard Test Method for Viscosity by Ford Viscosity Cup
Description:
Significance and Use
5.1 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 to Newtonian or near-Newtonian liquids.
5.2 There are other types of apparatus for measuring viscosity in the laboratory that produce more accurate results.
Scope
1.1 This test method covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, and related liquid materials with the Ford-type efflux viscosity cup. If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D2196 should be used.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
