    Scope - (Show below) - (Hide below)

    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.
