A revolving
cylinder is slowed down by the viscosity of the sample
in which the former is immersed. The apparatus consists
of a revolving cylinder driven by a motor with
adjustable speeds. The deflection obtained with a given
speed and cylinder is directly related to the viscosity.
This test method
covers the determination of the amount of carbon residue
left after evaporation and pyrolisis of an oil, and is
intended to provide some indication of relative
coke-forming propensity. The method is generally
applicable to relatively non volatile petroleum products
which partially decompose on distillation at atmospheric
pressure. The principle consists on heating a sample at
550°C during 20 min. in a coking bulb and then weighing
the residue.

Undesirable foaming
characteristics in lubricating oils can be a serious
problem leading to loss of lubrication, overflow, and
cavitation with ultimately a possibility of mechanical
failure.
With increasing operating temperature in oil systems,
there is requirement is to assess the tendency of oils
to foam at 150°C.

A test chamber of 15 ml is maintained at 0,1 KPa and
37,8°C.
When these conditions are respected, a 3 ml sample at 0
°C is introduced into the test chamber with an automated
syringe located in the sample container. Under
temperature action, a volume of the liquid sample
becomes gaseous. This change modifies the absolute
pressure of the test chamber. riseWhen the thermal
equilibrium is reached, the resulting rise in pressure
in the chamber is measured.
