BS PD ISO/TS 6336-22:2018 describes a procedure for the calculation of the micropitting load capacity of cylindrical gears with external teeth. It has been developed on the basis of testing and observation of oil-lubricated gear transmissions with modules between 3 mm and 11 mm and pitch line velocities of 8 m/s to 60 m/s. However, the procedure is applicable to any gear pair where suitable reference data are available, providing the criteria specified below are satisfied.Cross References:ISO 53ISO 1328-1ISO 6336-2ISO 1122-1ISO 6336-1 ISO/TS 6336-21ISO 10825AGMA 925-A03BGA-DU P602ISO/TS 6336-20
