ISO 14635-1:2000 PDF

Scope: This part of ISO 14635 specifies a test method based on an FZG 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. note: 2) FZG = Forschungsstelle fur Zahnrader und Getriebebau, Technische Universitat Munchen (Gear Research Centre, Technical University, Munich), Boltzmannstraβe 15, D-85748 Garching, Germany.
