This standard GB/T 14248-1993 compared to the main technical content changes as follows. --- Increasing the terms and definitions; --- On the service brake test program have been adjusted; --- The parking brake to the parking brake, a clear test of time; --- Remove the hot brake tests. From the date of implementation of this standard instead of GB/T 14248-1993. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee (SAC/TC201) Agricultural machinery centralized. This standard was drafted. Chinese Academy of Agricultural Mechanization Sciences, Fukuda Lovol International Heavy Industry Co., Ltd. The main drafters of this standard. Chen Ge, Chen Jun Bao, Zhu Jinguang, Yue Qin. This standard replaces the standards previously issued as follows. --- GB/T 14248-1993. Harvester braking performance measurement method1 ScopeThis standard specifies the self-propelled harvesting machinery and equipment brake test parameter measurement accuracy, test conditions, the service brake test, parking Brake test. This standard applies to wheeled, crawler harvesting machinery.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Harvesting machinery or decelerate the motion to stop the movement of the device. 2.2 Even in the case of unmanned slope, so that harvesting machinery to keep it stops state apparatus. 2.3 Brake operating device is actuated to start harvesting machinery to a full stop machine travel distance. 2.4 The braking distance and braking initial velocity calculated deceleration. Rao = vp 2S (1) Where. Rao --- average deceleration in meters per second squared (m/s2); Vp --- brake initial velocity in meters per second (m/s); S --- braking distance in meters (m). 2.5 It means the braking deceleration device or a non-contact instrument detected by the vehicle speed when recording the average sustained deceleration in the instrument. 2.6 Driver brake operating force applying means combined. For the pedals, steering force is measured along the loading point and the driver's hip even Opponents controls, measured along the loading point and the operating force of the driver shoulder connection; the line.3 test parameter measurement equipment and accuracy3.1 Test Equipment Are. operating force measuring device, pulling force, braking deceleration device or non-contact speed meter, timer, steel tape measure, thermometer, pressure Table, anemometer and test ramps. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 14248-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 14248-2008_English as soon as possible, and keep you informed of the progress.
