...Lorena Deleanu; Constantin Georgescu; Sorin Ciortan; Liviu Catalin Solea Purpose – The purpose of this paper is to establish the influence of oil concentration in oil-in-water emulsions on their flammability on hot surfaces and on their viscosity. The interest in fire test systematization...

... and experiments, which are also specially introduced in this paper. © MCB UP Limited 2001 Hydraulics Pumps Lubrication Tests Material The earliest hydraulic systems used water as the hydraulic fluid. This restricted the working temperature range and caused corrosion as well as lubricating...

...Bill Wilson Examines the issues surrounding fuel lubricity by explaining the background to the problems surrounding lubricity in diesel engines. As the need for low sulphur diesels arose it became clear that a universally accepted bench test was required and ISO working group SC7/WG6 was set up...

...Tom Lecklider A reciprocating sliding pad on plate boundary lubrication friction test is described. Typical friction waveforms are shown and compared with the output from an automated measuring system based on a digital storage oscilloscope. © Company 1995 Analysis Boundary lubrication...

...Channan Matharuh; L. Rudd Details the friction and wear testing facilities offered to civilian customers by the DRA and lists recent projects. Cylinder and ball on plate fuel lubricity and fire resistant hydraulic fluid tests are described with line drawings and the results obtained tabulated. ©...

...Bill Wilson Describes the testing and lubricating mechanisms of Slick 50, a solid lubricant engine oil additive containing PTFE for reducing friction and wear. Gives the results of long term engine tests by the Southwest Research Institute, Texas, monitored by radioactive tracer, exhaust emission...

...D.F. Neadle Describes the three main methods of used oil recycling. Details the laundering process carried out by Smallman Lubricants and the subsequent quality tests. Refers to environmental and health aspects. Mentions three other reprocessing technologies. © MCB UP Limited 1994...

...T.W. Dicken Describes the requirements for biodegradability, defines the different terms and lists the various tests used. Outlines how greases can cause pollution. Details the main primary biodegradability test for lubricants and how to formulate greases to optimize breakdown in the environment...
