GB/T 6229-2007Test methods for walking tractors (English PDF)

Foreword

This standard is GB/T 6229-1995 "tractor test" amendments. This standard compared with GB/T 6229-1995, the main technical changes as follows:

--- Refers to the standard adjustment for the current valid standards;

--- Increased JB/T 7282 "tractor oil varieties and specifications selection";

--- The "test parameter measurement equipment and accuracy" to "test equipment and measuring parameters of tolerance";

--- Increased in the test tractor oil selection requirements of different specifications;

--- Increased at the start of the test, the tire tread height should not be less than 65% of new tire requirements;

--- Increased when the PTO power (or engine bench) test and traction power tests, the fuel pressure requirements;

8.2.1 original standard noise measurement test conditions were modified;

8.3.1 of the original standard dynamic environmental noise measurement content has been modified;

--- Test reports have been some changes, and the test report format on Appendix A;

--- Original Appendix A centroid height coordinate measurement moved in Appendix B, and to increase the quality of the measurement cycle using the centroid method of height method. Since the implementation of this standard replaces GB/T 6229-1995. Appendix A of this standard is a normative appendix, Appendix B is an informative annex. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee of the tractor. This standard was drafted. Luoyang Tractor Research Institute, National Tractor Quality Supervision and Inspection Center. The main drafters of this standard. Lijing Zhong, Lile Chen, Xie Zhi bridge, Liu Lingwen. Tractor Test Method

1 Scope

China's national test methods for walking tractors. The walking tractor - the two-wheeled machine the operator follows on foot, steering by handlebars - is one of the most consequential machines in Chinese agriculture, because it mechanised the small terraced and irrigated plots that a four-wheeled tractor cannot work. Tens of millions are in use, and the same machine ploughs, drives a pump or a thresher through its power take-off, and hauls a trailer on the road. That last use is why the test programme reads as it does: a machine sold as agricultural equipment is in practice a road vehicle carrying a load, and its brakes on a slope are a safety matter rather than a performance figure. The standard specifies the general requirements for testing, the measurement of machine parameters, and tests of the power take-off, the controls, parking brake performance on a slope, noise, drawbar power, cold starting, high temperature suitability, and operational use.

This standard specifies the general requirements for testing tractor, machine parameters measured, PTO test, control test, ramp parking brake Dynamic test, noise measurement, traction power tests, cold start test, high temperature suitability test, using a test. This standard applies to tractor (hereinafter referred to as tractors).
