Note that bulb C and J have
separate calibration constants which shall be used for calculating
their respective viscosity determinations from the measured
efflux times. If measuring two viscosity determinations in this
manner using both bulbs C and J, ensure that the two
determinations do not differ by more than the precision
estimate for the test method used (for example, the determinability
limit in the Precision of Test Method D445) – see Note
A3.2. If the flow time is less than the minimum specified for
the viscometer, select a clean, dry viscometer with a smaller
diameter capillary and repeat stepsA3.2.2 – A3.2.6.
