    Scope - (Show below) - (Hide below)

    This part of ISO14635 specifies a test method based on an FZG1) four-square test machine for determining the relative load-carrying capacity of semi-fluid gear greases defined by the gear surface damage known as scuffing.

    This method is useful for evaluating the scuffing load capacity potential of semi-fluid gear greases of NLGI classes 0 to 000, typically used with highly stressed gearing for enclosed gear drives. It can only be applied to greases giving a sufficient lubricant flow in the test gear box of the FZG test machine.

    NOTE The test method is technically equivalent to DIN Fachbericht 74.
