JB/T7282—2004
This standard is a revision of JB/T7282-1994 "Selection of varieties and specifications of tractor oil". Compared with JB/T7282-1994, the main changes of this standard are as follows: 1. The quality requirements for CA-grade diesel engine oil in the original standard have been cancelled; the quality index of light diesel oil shall comply with the requirements of GB252-2000; the quality index of N46, N68 and N100D in hydraulic and transmission dual-purpose oils shall be cancelled; the quality index of motor vehicle brake fluid shall comply with the provisions of GB/T12981-2003. This standard replaces JB/T7282-1994.
Appendix A, Appendix B and Appendix C of this standard are all normative appendices. This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Tractor Standardization. This standard was drafted by Luoyang Tractor Research Institute, and China First Tractor Group Co., Ltd. and Gansu Agricultural Machinery Appraisal Station participated in the drafting. The main drafters of this standard are: Li Haimei, Yang Qinshou, Han Meixiao, Xu Huijuan, and the previous versions of the standards replaced by this standard are: JB/T7282-1994.
