Chem-TechTM Laboratories is a leading provider for Metal Working Fluid analysisServices. Metal Working fluid is a type of coolant and lubricant designed specifically for metalworking and machining processes. There are various kinds of Metal Working fluids, which include oils, oil-water emulsions, pastes, gels, aerosols (mists), etc.
Depending on context of use and on which type of cutting fluid is being considered, it may be referred to as Cutting oil, Metal Working Fluid, Coolant, Rust Preventing Oils or Lubricant. Cutting fluids degrade over time due to contaminants entering the lubrication system or sump. Chem-TechTM can test cutting oils for it’s following for its lubrication & rust prevention properties to assist in maintaining the quality of oil.
Chem-TechTM has the capability for testing following types of Metal Working oils:
Chem-TechTM carries out testing of Metal Working Fluids as per internationally accepted ASTM, ISO & IS Test Standards.

Kinematic Viscosity is a measurement of the resistance of the oil to flow through a capillary tube of the viscometer. It is the most fundamental property of a lubricant. Viscosity of lubricants is measured in case of fresh oils to check the Grade of the oil . in case of used oils it gives idea about change in physical properties due to oxidation, dilution or any external contamination. It is the most fundamental property for testing of any lubricant or petroleum product.
Methods Adopted by Chem-Tech for Viscosity Determination:
Total Acid Number determines the amount of acid present in the lubricant. Acidity of the lubricant increases due to the stresses or environmental factors affecting the lubricant. Excess amount of acid in the lubricant will lead to corrosion or failure of equipment.
Methods adopted by Chem-Tech Laboratories for Acid Number Analysis:
This test method covers the determination of ash in the range 0.001–0.180 mass %, from distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes, and other petroleum products, in which any ash-forming materials present are normally considered to be undesirable impurities or contaminants . The test method is limited to petroleum products which are free from added ash-forming additives, including certain phosphorus compounds and Organo Metallic Additives.
Ash can result from oil or water-soluble metallic compounds or from extraneous solids such as dirt and rust.
Methods adopted by Chem-Tech for Determination of Ash Content:
Flash Point is the lowest temperature at which the vapours of the petroleum product catches fire momentarily in presence of air when an ignition source is applied to the sample.
Flash point are normally conducted by three methods:
Methods Adopted by Chem-Tech for Flash Point Determination:
Demulsibility Test for lubricants determines the lubricants ability to separate from water.
This test method provides a guide for determining the water separation characteristics of oils subject to water contamination and turbulence.
Methods adopted by Chem-Tech for Determination of Demulsibility:
