A range of testing related articles, some of the articles are about the various tests associated with lubricant characteristics and data, other articles are on the subject of lubricant performance.
Water ingress protection is one of most common reasons for considering the use of a connector lubricant. The ‘go to’ grease in our range for moisture/water protection is Tribosyn 330. It should be noted that we have a range of connector lubricant products available for other connector problems such as…
One of the most common misconceptions we come across is that some electrical engineers think that using one of our specialist connector lubricants will cause extra circuit resistance/circuit impedance across a connector or circuit – this is not correct! As a number of customers ask this same question about possible…
The grease low temperature torque test measures how a grease inhibits the motion of a slow rotating ball bearing at a low temperature: Test is run below -20°C at 1 RPM. Starting torque and running torque is recorded after 60 minutes. Very useful data point for selecting a grease for…
The Knudsen effusion test method is used to determine the vapour pressure at several temperatures. Below is an example of how the Knudsen vapour pressure test results are displayed on a technical data sheet of one of our lubricants: As you will see, our chosen unit of measure is Torr.
The purpose of the Thermal Stability test is define the thermal stability of a lubricant, a Thermo-Gravimetric Analyser (TGA) is used. The lubricant is exposed to the required test temperature and held there for 24 hours. A plot of weight loss vs time is produced. Our thermal stability test method:…
The purpose of the Pour Point test is to help define the lowest operating temperature for an oil. During this relatively simple test, the temperature is slowly reduced and it is noted at what point the fluid becomes too viscous to flow. Some times Pour Point is referred to as…
Viscosity Index (VI) is a data point reference used on our technical data sheets. The VI data point or scale was originally devised by the Society of Automotive Engineers (SAE) in the USA. VI is a unit-less number that gives an indication of how a lubricating oil (or base oil…
Kinematic Viscosity (KV) is a type of viscosity data point that you will see on all our synthetic lubricant technical data sheets. There are different ways to measure the viscosity of a lubricant as the subject matter is not simple. Kinematic Viscosity is an oil/fluid resistance to flow under the…
The Oxidative Stability test (ASTM D-6186) measures the ability of a lubricant to resist oxidation at elevated temperatures. The test can be conducted on an oil or grease. Typically reported in ‘minutes’ – The greater the time to exotherm, the better the oxidative stability of the lubricant. Test conditions are…
If you are trialling the use of a grease or oil in a prototype device then you will appreciate how crucial lubricants can be; extending the functional life of components, improving the tactile feel of customer operated controls…the reasons to include a lubricant are many and well worthwhile. Before you…
