Lubricant specifications are internal documents that contain the technical standards, performance requirements and industry approvals for every lubricant used in the facility or fleet. They may include information on product safety, proper disposal or alternative products available on the market.

 

Among the lubricants typically found in these specifications are gear oils, turbine oils, hydraulic fluids, compressor oils, greases, solid lubricants, multi-purpose bearing oils, engine oils, cutting fluids, total-loss lubricants and others.

For small facilities or fleets, creating lubricant specifications can be a relatively simple exercise. However, the complexity often increases according to the facility’s equipment diversity or the number of sites involved. The more complex the facilities or the higher the number of sites involved, the greater the value of creating specifications.

Experienced and laboratory experts of industrial and automotive lubricants with the most advanced equipment in the world perform lubricant analysis services with excellent accuracy and speed and in accordance with the standards of petroleum products ASTM , IP , DIN , BS , IPS , API ,SHELL , NACE for you, our dear customers. The results of these analyzes are analyzed and interpreted by the director of the laboratory and provided to the customer.

 

These are the intrinsic physical and chemical properties of the lubricant. Here it is important to identify not only the testing parameters used but also the expected test results.

An ASTM or appropriate test method should also be referenced. Examples include ISO viscosity grades (ASTM D2422), minimum viscosity index (ASTM D2270), aniline point (ASTM D611), flash point (ASTM D92) and thickener type.

You do the process to order correctly. Exactly which lubricant you are requesting and which tests you are requesting, please write and indicate in detail so that you and we do not make any mistakes in how the tests are performed.These are the lubricant approvals or endorsements required by the specific machine(s) in which the product is intended to be used.

 

They may come from original equipment manufacturers (OEMs) or other industry organizations, such as the American Gear Manufacturers Association (AGMA), the National Lubricating Grease Institute (NLGI), etc.

Please note that some lubricants may claim a certification or approval for certain technical standards or OEM specifications, while others may only “comply with” the standard or requirement but are not necessarily approved or certified. This may be particularly significant when complying with equipment warranty requirements.

yekta group has an extensive network of lubricant and oil condition monitoring (OCM) laboratories, working with clients to ensure rapid, prompt and reliable testing and reporting expertise. Sample shipment is easy to arrange, with the labs providing fast, expert, quality control, evaluation, and troubleshooting services.

In engine oil, for example, lower viscosity improves fuel economy at higher engine speeds, but at lower engine speeds the oil film is insufficient and the increased contact with metal parts reduces fuel economy.

 

We have therefore developed a technique to assess the behavior of friction modifiers in the nanoscale gaps between solid surfaces, with the aim of identifying friction modifiers that can characteristically reduce friction in mixed and boundary lubrication areas where more contact occurs between metals.

 

We are now developing engine oils with optimum friction modifiers selected and formulated on the basis of their functions at the molecular level. In addition, we are using a large synchrotron radiation facility (SPring-8) to visualize the behavior of macromolecules in oil and to develop next-generation engine oils that can control these macromolecules.

Lubricants such as oils and greases contribute to the performance and longevity of machines and equipment by reducing friction and wear, cooling, and protecting surfaces.

 

We are contributing to the rapid development of products by understanding the properties of lubricants, analyzing changes in chemical composition during degradation, film formation on the friction surface, and microscopic morphological changes, estimating the lubrication mechanism using measurement and analysis technologies, and providing rapid feedback for base material selection and performance evaluation.

Lubrication Meaning : Lubrication is the control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. The lubricant used can be a fluid, solid, or plastic substance.

Although this is a valid definition, it fails to realize all that lubrication actually achieves.

Many different substances can be used to lubricate a surface. Oil and grease are the most common. Grease is composed of oil and a thickening agent to obtain its consistency, while the oil is what actually lubricates. Oils can be synthetic, vegetable or mineral-based as well as a combination of these.

The application determines which oil, commonly referred to as the base oil, should be used. In extreme conditions, synthetic oils can be beneficial. Where the environment is of concern, vegetable base oils may be utilized.

Lubricants containing oil have additives that enhance, add or suppress properties within the base oil. The amount of additives depends on the type of oil and the application for which it will be used. For instance, engine oil might have a dispersant added.

A dispersant keeps insoluble matter conglomerated together to be removed by the filter upon circulation. In environments that undergo extremes in temperature, from cold to hot, a viscosity index (VI) improver may be added. These additives are long organic molecules that stay bunched together in cold conditions and unravel in hotter environments.

This process changes the oil’s viscosity and allows it to flow better in cold conditions while still maintaining its high-temperature properties. The only problem with additives is that they can be depleted, and in order to restore them back to sufficient levels, generally the oil volume must be replaced.

 

The Role of a Lubricant

The primary functions of a lubricant are to: reduce friction , prevent wear , protect the equipment from corrosion , control temprature , control contamination , transmit power ,  provide a fluid seal.


Sometimes the functions of reducing friction and preventing wear are used interchangeably. However, friction is the resistance to motion, and wear is the loss of material as a result of friction, contact fatigue and corrosion. There is a significant difference. In fact, not all that causes friction (e.g., fluid friction) causes wear, and not all that causes wear (e.g., cavitational erosion) causes friction.

Reducing friction is a key objective of lubrication, but there are many other benefits of this process. Lubricating films can help prevent corrosion by protecting the surface from water and other corrosive substances. In addition, they play an important role in controlling contamination within systems.

The lubricant works as a conduit in which it transports contaminants to filters to be removed. These fluids also aid in temperature control by absorbing heat from surfaces and transferring it to a point of lower temperature where it can be dissipated.
