Application Summary AI generated
This standard specifies the classification system for internal combustion engine oils within the broader L-class lubricant framework. It is applied by manufacturers and users in the automotive, marine, and industrial engine sectors to categorize oils based on viscosity, performance characteristics, and intended engine type (e.g., gasoline, diesel, or two-stroke). The classification aids in product selection, quality control, and technical specification for engine oil procurement and testing.
