Scope

1.1 These specifications cover 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 6.

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 D445 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.
