The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures. [1] [2] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades.
Based on a method published in 1931 by H.N.Marsh, [1] a Marsh cone is a flow cone with an aspect ratio of 2:1 and a working volume of at least a litre. A Marsh funnel is a Marsh cone with a particular orifice and a working volume of 1.5 litres.
A Mooney viscometer MV 2000 Mooney Viscometer. A Mooney viscometer or rotating disk viscometer is an instrument used for measuring the Mooney viscosity of rubbers. [1] Invented in the 1930s by Melvin Mooney, [2] it contains a rotating spindle and heated dies, the substance encloses and overflows the spindle and the mooney viscosity is calculated from the torque on the spindle.
Brookfield Engineering is an engineering and manufacturing company with headquarters in Middleboro, Massachusetts.It is a subsidiary of the conglomerate Ametek.Its product line includes laboratory viscometers, rheometers, texture analyzers, and powder flow testers as well as in-line process instrumentation.
If a test with any geometries runs through a table of several shear rates or stresses, the data can be used to plot a flow curve, that is a graph of viscosity vs shear rate. If the above test is carried out slowly enough for the measured value (shear stress if rate is being controlled, or conversely) to reach a steady value at each step, the ...
The cold-cranking simulator (CCS) is a device used to determine the low temperature performance of lubricants, when starting a cold engine (i.e. cold-cranking).In this condition, the only energy available to turn the engine comes from the starter motor and the battery, and it has been widely assumed that the system acts as a constant power viscometer.
The J300 identifier was attached around 1962. The criteria were reformulated in 1967 to use kinematic viscosity in centiStokes and the cold-cranking simulator. The 15W grade was added December 1975. [11] [19] In 1980, 0W and 25W grades were added, and a low-temperature pumpability test. Grade 60 was re-added in 1987. HTHS viscosity was added in ...
Zahn Cup . A Zahn cup is a viscosity measurement device used in the paint industry. It is commonly a stainless steel cup with a tiny hole drilled in the centre of the bottom of the cup.
