American Society for Testing and Materials (ASTM). urrent edition approved May 15, 2005. Published June 2005. Originally approved in 1983. Last previous edition approved in 2000 as D 4287 – 00. 3 p. This test method covers the determination of the viscosity of paints, varnishes, and related products at a rate of shear of 12 000 s −1.
Paints and varnishes that dry very rapidly may not give reproducible results with this test method. Measurements made at elevated temperatures may also give poor precision due to loss of volatiles and to drying.
