NOTE 3—Precision and bias of kinematic viscosity measurements for
flow times as low as 10 s has been determined for automated instruments
tested with the sample types listed in 17.4.1.
6.2 Viscometer Holders—Use viscometer holders to enable
all viscometers which have the upper meniscus directly above
the lower meniscus to be suspended vertically within 1° in all
directions. Those viscometers whose upper meniscus is offset
from directly above the lower meniscus shall be suspended
vertically within 0.3° in all directions (see Specifications D446
and ISO 3105).
