About This Item
ASTM D6375 is the standard test method for measuring evaporation loss of lubricating oils by thermogravimetric analyzer (TGA) using the Noack method. It provides a controlled way to evaluate how a lubricating oil responds to heat and mass loss under test conditions, which is important for comparing product performance and supporting quality decisions. As an ASTM standard, it is commonly used where consistent laboratory testing and clear technical reference matter.
Purpose of ASTM D6375
The purpose of ASTM D6375 is to define a repeatable laboratory procedure for determining evaporation loss in lubricating oils with a thermogravimetric analyzer. The Noack method is widely associated with assessing volatility behavior, and this standard helps create a consistent basis for that measurement. By using a defined test method, laboratories and product teams can generate results that are more suitable for comparison, specification review, and technical evaluation of oil performance.
Common use cases of ASTM D6375
ASTM D6375 is commonly used in laboratory testing of lubricating oils where evaporation loss is a relevant performance characteristic. It may support product development, routine quality control, and comparative evaluation of oil formulations using TGA equipment. The standard is also useful in procurement or compliance workflows when a defined Noack-type test method is needed to document volatility-related behavior. Its practical value is highest when consistent, repeatable test conditions are required.
Why ASTM D6375 matters
This standard matters because evaporation loss can affect how a lubricating oil performs in service, especially when heat exposure is a concern. ASTM D6375 helps reduce ambiguity by providing a recognized method for measurement, which supports more reliable product comparison and specification use. For manufacturers, laboratories, and buyers, that consistency can improve quality control, limit testing disputes, and strengthen confidence in technical claims tied to volatility or mass loss behavior.
