Foreword

Section 3.2 and Chapter 4 standard is mandatory, the rest are recommended. This standard was drafted in accordance with rules GB/T 1.1-2009 given. Instead of the standard GB 5903-1995 "closed industrial gear oil." The main changes in this standard compared with GB 5903-1995 See Appendix A. This standard method using Reference redrafted ISO 12925-1.1996 (2001) "Closed System gear lubricant specifications" (English Edition), United States Gear Manufacturers Association standard ANSI/AGMA9005-E02 "industrial gear lubrication" (in English) the preparation, and ISO 12925-1.1996 and ANSI/degree of consistency AGMA9005-E02 is non-equivalent. This standard petroleum products by the National Standardization Technical Committee Technical Committee petroleum fuels and lubricants and lubricant (SAC/TC 280/SC1) centralized. Drafted by. China PetroChina Lubricating Oil Company, China Petroleum & Chemical Corporation petrochemical Science and Engineering Research Institute, China Petroleum and Chemical Corporation lubricants branch.
