Foreword
This standard is a reference to JB/T6294-1992 ( Revision of "Agricultural Tractor Type Inspection Rules". When revised, the writing format of this standard complies with the provisions of GB/T1.1-2000 "Standardization Work Guidelines Part 1: Standard Structure and Writing Rules
Rules" Compared with JB/T6294-1992, the main changes are as follows: - The items of tractor complete machine performance inspection and component bench durability inspection have been added: the inspection standards for the added inspection items have been clarified; the basis for the reliability assessment of the whole machine has been clarified. This standard replaces JB/T6294--1992.
This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Tractor Standardization Technical Committee. This standard is drafted by the National Tractor Research Institute. The Quality Supervision and Inspection Center and China YTO Group Co., Ltd. participated in the drafting.
The main drafters of this standard are: Gao Bo, Han Meixiao, and Liu Lingwen. The previous versions of the standard replaced by this standard are: GB/T3870. —1983, JB/T6294-1992.1 Scope
