The Applied Technical Services Family of Companies (ATS FoC) performs oil viscosity testing to assess how easily oil flows under specific conditions. Viscosity is essential for lubricants, hydraulic fluids, fuels, and industrial oils. Variations in viscosity can impact equipment performance, lubrication, and product consistency. ATS offers professional laboratory testing for organizations requiring reliable oil viscosity data. Our services support quality control, product development, material evaluation, and condition monitoring.
Why Is Oil Viscosity Testing Important?
Oil viscosity affects fluid performance in its intended application. Excessive viscosity can hinder flow and raise operating demands, while low viscosity may result in inadequate lubrication or fluid-film protection. Testing enables organizations to determine if an oil meets specified requirements and provides valuable data for investigating changes in oil samples. Common oil viscosity testing applications include:
- Evaluating lubricant quality
- Verifying product specifications
- Supporting quality control programs
- Investigating lubricant degradation
- Comparing new and used oil samples
- Evaluating potential contamination
- Supporting research and development
- Characterizing petroleum-based and synthetic fluids
How Is Oil Viscosity Tested?
Our ISO 9001:2015-registered, ISO/IEC 17025:2017-accredited testing laboratories evaluate viscosity using standardized test methods selected for the sample and application. ASTM D445 is a commonly used standard for determining the kinematic viscosity of transparent and opaque liquids.
The appropriate testing method depends on factors such as oil type, temperature range, and measurement requirements. Testing at controlled temperatures ensures results are consistent and reliable. ATS can recommend suitable testing approaches based on your objectives and relevant specifications.
Who Requires Viscosity Testing?
Oil viscosity testing benefits organizations in various industries. Manufacturers use it to evaluate incoming materials and verify finished products, while equipment operators rely on laboratory analysis to assess used lubricants. ATS performs oil viscosity testing for clients operating in a wide range of industries, including but not limited to:
- Automotive and transportation
- Aerospace
- Industrial manufacturing
- Oil and gas
- Power generation
- Chemical processing
- Heavy equipment
- Lubricant manufacturing
- Research and development
Viscosity Testing for Quality and Condition Evaluation
Viscosity testing offers valuable insights when comparing oil samples. Assessing both new and used oil can help identify changes that may require further investigation. A significant change in viscosity may result from thermal exposure, oxidation, contamination, evaporation, or mixing with another fluid. ATS conducts viscosity testing as part of a comprehensive analytical program when further characterization is needed.
