Web1.2 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 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. WebSecond, is the fact that glass expands with increasing temperature, so the volume of a container also increases. By convention, volumetric glassware is always calibrated at 20 °C. Since the temperature at which you do the calibration may be somewhat different there is a small correction for the cubic coefficient of expansion of glass. robert bernard sherbrooke
