ISO/TC 60/SC 2 Gear capacity calculation
International Standard
21.200 Gears
This part of ISO 14635 specifies a test method based on an FZG2_ four-square test machine to determine the
relative load-carrying capacity of lubricating oils defined by the gear-surface damage known as scuffing. High
surface temperatures due to high surface pressures and sliding velocities can initiate the breakdown of the
lubricant films. This test method can be used to assess such lubricant breakdown under defined conditions of
temperature, high sliding velocity and stepwise increased load.
NOTE This method is technically equivalent to ASTM D 5182-97, DIN 51354-1 and DIN 51354-2, IP 334/90 and
CEC L-07-A-95.
