Test Method
Determines the tendency of lubricating grease to separate oil during
storage in a 35 lb pail. The sample is placed on a sieve inside a special
test cell and subjected to 0.25psi (1.72kPa) air pressure at constant
temperature. Any oil that bleeds from the grease during a 24 hour period is
collected in the cell and weighed.
Oil Separation Apparatus
. Conforms to ASTM D1742 and related specifications
. Four sample capability
. Controls temperature and air pressure
Consists of pressure bleeding test cells with air pressure regulation system
and constant temperature air cabinet.
Pressure Bleeding Test Cell - Type A test cell includes cup assembly with funnel
and positioning seat for beaker; cover with air inlet fitting; and 200-mesh stainless
steel sieve strainer with brass support ring. Bayonet type connection and
o-ring seal provide tight closure between cover and base. Cup, funnel and base
are constructed of chrome plated spun copper. Order test beaker separately.
Constant Temperature Air Cabinet
Provides a constant temperature environment and regulated air pressure per ASTM specifications. Consists of an
insulated airtight cabinet with pressure system to accommodate four pressure
bleeding test cells. Equipped with electric heater, solid state controller, cooling
coil and circulating fan for efficient temperature control at 77°F (25°C).
Pressure system includes air inlet pressure regulator with gauge, cartesian
manostat, manifold with control valves for four test cells, output gauge,
manostat and gas washing bottle. Built-in pressure relief valve protects against
pressure surge. Cabinet is constructed of double-wall stainless steel with full
insulation. Order thermometer and pressure bleeding test cell separately.
