ISO/TS 6521-2:2021 is an international standard that specifies the minimum requirements for lubricants used in flooded rotary air compressors, including both vane and screw types, particularly focusing on the "DAG", "DAH", and "DAJ" categories of lubricants, which can be either mineral or synthetic based; essentially defining the quality standards for compressor oils within these specific classifications.
