Abstract: Effects of Oxygen on grease or another organic paste product can be evaluated with a modified version of the ASTM D942 test methodology for oxidation stability of lubricating greases or other organic paste products by employment of an oxidation pressure vessel, in which at least one of (A) a very small sample of the grease or other organic paste product is deployed for testing within the oxidation pressure vessel such that the sample has an enhanced surface area to mass ratio, and (B) a temperature other than about 99° C. is employed during the testing. In general, the testing is carried out under oxidation pressure conditions. The sample may be evaluated with respect to Oxygen uptake. Additional technique(s) directed to oxidation and/or other properties of the sample may be carried out before to after any Oxygen uptake evaluation, for example, FTIR analysis and/or ATR-FTIR analysis.

Abstract: A significantly improved version of the ASTM D942 Test Method, with apparatus employable to effect the same, is provided. This is useful in measurement of grease oxidation.

Abstract: Instrumentation embraces an at least partially automated rotational tapered bearing simulator viscometer having electronic control and/or monitoring that includes task unit electronics, which includes a task unit electronics interface.

Abstract: Elevated temperature liquid testing apparatus and methodology in which a thin film of test liquid and a reactant/control gas are provided about the top of a depositor member that is surrounded by a special mantle, for example, a substantially cylindrically walled glass mantle. As an oxidative engine oil test, it may mimic turbocharger conditions of a modern internal combustion engine. For example, employing moist air, the apparatus can test a thin film of engine oil for oxidation deposits at a predetermined temperature, say, 285° C., 290° C., or cycled between 285° C. or 290° C. and 320° C. or 330° C.

Abstract: An active pharmaceutical ingredients (API) or related substance (RS) can be tested for stability by placing the API or RS in an instrument containing a pressure-controllable atmosphere, controlling the pressure of the atmosphere in the instrument for a predetermined time, and evaluating the API or RS for stability. Testing can be carried out also at predetermined temperature(s) and/or under the influence of gaseous trigger(s) and so forth. For instance, an API sample can be placed in a bomb test instrument/reactor, oxygen as a gaseous trigger can be introduced to contact the API sample under constant and/or ramped temperature(s) and elevated pressure(s) for predetermined time(s), and the API sample can be evaluated for stability. An insert carousel may hold a sample of API(s) and/or RS(s) and/or aliquot(s) of sample(s) of API(s) and/or RS(s) for insertion into the bomb test instrument/reactor.

Abstract: Apparatus includes a pivotable, cradling framework that can hold a rotatable bomb instrument, which can include a hollow cylinder and a grease rack. This may be employed to effect a significantly improved version of the ASTM D942 Test Method. The same is useful in measurement of grease oxidation.

Abstract: Grease wear test device includes a body in a form of a collar having an outer surface, a first side and an opposing second side, which are open to form a hollow, open channel through the body, which has a center axis, into which opposing vee blocks can be inserted; and perpendicular to the center axis, a pair of opposing holes through and open to the outer surface of the body and the cylindrical inside wall, through which a cylindrical test journal (falex pin) can be inserted for contact in general with opposing vee-shaped channels of the inserted, opposing vee blocks, and for rotation during testing. The device can be used to modify a falex pin and vee block device, to receive and contain a small sample of grease or another organic paste product for testing such as a modified version of an ASTM D2670 test method for measuring wear properties of fluid lubricants (falex pin and vee block method).

The device can have at least one of an insulating lower disc or washer; a plurality of staggered heating bands encompassing a stationary housing; a dry scan port; a rear upper and/or lower port; and an extraction/injection fitting for access to the interior of the stationary housing. The device may be used to react or attempt to react substance(s), for example, generally as in ASTM Method D2272 testing of turbine oil.

Abstract: Low heat-transmissible spindle for rotary viscometry includes an elongate, radially balanced, straight shaft made of a suitably stiff material having a low heat-transmission value, with a head monolithic with the shaft which can contact and interface with a test fluid to yield drag from the contact and interface when the spindle is rotated in the fluid; and a spindle coupling nut attached to the shaft opposite the head. For example, the shaft may be made of a woven glass fabric cylinder laminated with a synthetic resin, and the head made of stainless steel. A rotary viscometer can be equipped with the spindle, and fluid viscosity can be determined by employing the same in a rotary viscometric protocol, for example, ASTM D 2983.
