The Society of Automotive Engineers (SAE) Industrial Lubricants Committee has developed a number of industrial, non-production lubricant performance specifications. The purpose of these voluntary SAE specifications is to: a. Define minimum performance requirements for industrial lubricants. b. Provide lubricant suppliers with performance targets for a minimum number of key industrial lubricants. c. Improve the availability of these lubricants to member companies. d. Provide a plant oriented, user friendly, classification system using common test standards and properties. ISO Standard 6743 - Lubricants, industrial oils and related products (class L) - Classification is the foundation for these documents. a. Performance characteristics and test procedures are specified. b. For information, equivalent ISO, DIN, CEN, BSI, ASTM, AFNOR, CETOP, and IP test methods are referenced.
