Lubricating Oil Evaporation Loss Tester 

Understanding the Role of Lubricating Oil Evaporation Loss Testing in Industrial Maintenance

The performance of lubricating oil directly affects the reliability and longevity of engines and machinery. Among the critical parameters to assess is the evaporation loss. The Lubricating Oil Evaporation Loss Tester from Changsha Friend Experimental Analysis Instrument Co., Ltd. is engineered to evaluate this property through simulated high-temperature operating environments.

Evaporation of lubricating oil leads to a reduction in oil volume, viscosity changes, and the formation of carbonaceous deposits. These changes impair lubrication efficiency and can lead to engine wear. The testing procedure typically involves heating the oil to a specified temperature under controlled airflow and measuring the weight loss over time. The result reflects the oil’s resistance to volatility.

Applicable to automotive, aviation, and industrial machinery oils, this tester aids manufacturers and quality control labs in selecting or formulating oils with improved thermal stability. The method conforms to recognized standards such as ASTM D5800, ensuring test consistency across global laboratories.

The tester is designed with safety measures, digital temperature controls, and precision air supply modules. Data acquisition is streamlined, with repeatability and accuracy maintained across different samples.

Before initiating a test, the sample must be prepared according to standard volume and pre-conditioned to eliminate moisture contamination. The tester's air pressure should be regulated and verified through its integrated flow meter, ensuring compliance with the standard requirements.

Temperature control is another essential parameter. The device’s precision heater and digital PID controller must be validated using a certified thermometer before use. Proper sealing of the test chamber prevents vapor loss and ensures accurate measurement.

Routine maintenance, such as cleaning residue from the evaporation chamber and inspecting the air filtration system, contributes to the longevity of the equipment. Regular validation using reference oils also helps maintain data integrity.

This tester supports R&D initiatives, lubricant certification, and batch consistency verification, making it indispensable in professional labs and oil production facilities.
