ASTM D7395-18(2023)

1.1This 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.

1.2Viscosity 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.

1.3If viscosity at a higher shear rate is needed, Test Method D4287, which describes viscosity measurement at 10 000 s^-1 to 12 000 s^-1 may be used.

1.4The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered standard.

1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
