Lubricants, industrial oils and related products (class L). Classification - Family D (Compressors) Ingestion-build-47182 1 Methods of charge control1 Scope This part of ISO 6743 establishes the detailed classification of lubricants for use in family D, air compressors, gas compressors and refrigeration compressors. The intention of this part of ISO 6743 is to provide a rationalized range of the most commonly used internationally available lubricants for air, gas and refrigeration compressors, without resorting to unnecessary restriction by specifications or products description.
