1.1 This test method covers the determination of the viscosity of paints and related products using a cone/plate viscometer at a shear rate of 500 s-1.
1.2 Viscosity values obtained by this method may be used as an alternative to results from No. 4 Ford cup measurements. The values from this method do not replicate Ford cup results, but can be used for quality control, producer-user specifications and viscosity reduction in the same manner that Ford cups are used.
1.3 If viscosity at a higher shear rate is needed, Test Method D 4287, which describes viscosity measurement at 10 000 to 12 000 s-1 may be used.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
