1. Scope
1.1 These specifications cover operating instructions for glass capillary kinematic viscometers of all the types described in detail in , , and as follows:
| Modified Ostwald viscometers, |
| Suspended-level viscometers, |
| Reverse-flow viscometers, |
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 D 445. 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 standard. No other units of measurement are included in this standard.
