ASTM D446 : 97e1

Standard Specifications and Operating Instructions for Glass Capillary Kinematic Viscometers

Standard Details

1.1 This standard gives specifications and operating instructions for glass capillary kinematic viscometers of all the types described in detail in Annex A1, Annex A2, and Annex A3 as follows:

Modified Ostwald viscometers, Annex A1

Suspended-level viscometers, Annex A2

Reverse-flow viscometers, Annex A3

1.2 The calibration of the viscometers is described in Section .

1.3 This standard covers some widely used viscometers suitable for use in accordance with Test Method D445. Other viscometers of the glass capillary type which are capable of measuring kinematic viscosity within the limits of precision given in Test Method D 445 may be used.

1.4 The values stated in SI units are to be regarded as the standard.
