ASTM WK43494

    Work Item: ASTM WK43494 - New Test Method for Calibration of Concentric Cylinder Rotational Viscometers

    (What is a Work Item?)

    Developed by Subcommittee: E37.08 | Committee E37 | Contact Staff Manager



    1. Scope

    1.1 This test method describes the calibration (or performance validation) of rotational viscometers in which the rotational element is immersed in the test fluid under ambient temperature conditions. It is not intended for cone-and-plate or parallel plate viscometers. 1.2 Calibration shall be performed using experimental conditions, such as temperature, viscosity range, and shear rate (rotational speed), as close as practical to those to be used for measurement of test specimens. 1.3 The values given in SI units are the standard. The values given in parenthesis are provided for convenience of the user. 1.3.1 Common viscosity units of Poise (P) are related to the SI units by the equivalency 1 cP = 1 mPas. 1.4 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.

    Presently used ASTM standards rarely contain information on the calibration of reported viscosity. This standard will add to the art by providing this procedure.
