A3.2.7 Using this viscometer after it has been thoroughly
cleaned and dried, or a second clean and dry viscometer, repeat
steps A3.2.3 – A3.2.6 making a duplicate determination of the
kinematic viscosity. If the two determinations agree within the
determinability given in Test Method D445 for the product
being measured, report the average of the calculated kinematic
viscosities. Note that the precision of the viscometers in Annex
A3 is slightly poorer than those in Annex A1 and Annex A2
(see 6.3.3).
