Standard Test Method for Calibration of Concentric Cylinder Rotational Viscometers
 N E2975

Annotation

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.

Calibration shall be performed with Newtonian reference materials 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.

The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

Common viscosity units of Poise (P) are related to the SI units by the equivalency 1 cP = 1 mPa·s.

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.

Стандартный метод тестирования для калибровки концентрических цилиндрических ротационных вискозиметров

Этот метод тестирования описывает калибровку (или проверка производительности) ротационных вискозиметров, в которых вращательный элемент погружен в тестовую жидкость при условиях температуры окружающей среды. Это не предназначается для конуса-и-пластины или параллельных вискозиметров пластины.
