ISO 6743-11:1990

Establishes the detailed classification for pneumatic tools and machines driven by compressed air. This classification system covers only lubricants which are in contact with the compressed air. Pneumatic tools or machinery may have other points of lubrication. This classification applies only for normal operational and environmental conditions. If abnormal conditions are encountered, the manufacture of the equipment and/or the supplier of the lubricant should be consulted. Should be read in conjunction with ISO 6743-0.
