Foreword

This revised standard adopts ISO 4020.2001 "Road vehicles - diesel fuel filter test method" (in English). This standard is based on ISO 4020. redrafted "With fuel filter test method for diesel road vehicles' (in English) 2001. This standard and ISO 4020.2001 The main difference is as follows. --- The standard test oil are used to produce domestic oil or oil available domestically produced oil modulation instead of ISO 4020 Oil standards, to meet the test requirements of the oil viscosity, easy to purchase, lowering the cost of test; --- Delete this standard ISO 4020 in ISO 3016.1994 Petroleum products determine the freezing point, ISO 3104.1994 Petroleum products Turbid liquid and transparent standards for the oil to determine the five test kinematic viscosity and calculation of dynamic viscosity, etc., with domestic production Oil and test methods in place; --- The standard delete nanoscale carbon black as an instantaneous filtration efficiency and life testing impurities removed nanoscale carbon black were The contents of each chapter test, also remove the "organic impurities (nanoscale carbon black)" and "inorganic impurities" terms, in line with a diesel engine Actual use of the fuel filter, operability is good; --- The standard delete the ISO 4020 standard preface; --- The revised standard using two or more parallel main oil pump when the water system so that accurate water metering; --- The revised standard hydraulic pulse fatigue test waveforms, more reasonable, good operability; --- With a decimal point "." Instead of a comma as the decimal point "." This standard replaces GB/T 5923-1986 "Test Method for automotive diesel fuel filter." This standard and GB/T 5923-1986 the main differences are as follows. --- This standard removes the carbon black and added one ISO 12103-M1 test impurities as an instantaneous filtration efficiency and life testing; --- The revised standard using two or more parallel main oil pump when the water system; --- The revised standard filter integrity test production methods; --- The revised standard hydraulic pulse fatigue test waveform diagram; --- This standard specifies the parameters of vibration fatigue test. The Standard Appendix A, Appendix B, Appendix C, Appendix D and Appendix E are normative appendix. Appendix F of this standard is an informative annex. This standard was proposed by the National Development and Reform Commission, People's Republic of China. This standard by the National Automotive Standardization Technical Committee (SAC/TC114) centralized. This standard was drafted. China Automotive Engineering Research Institute (emission and energy-saving test Chongqing Municipal Key Laboratory of vehicle), Bengbu Jinwei filter Qing Co., Ltd, Chengdu Zeren Industrial Co., Ltd., Guangzhou Jia-Bin Industrial Co., Ltd., Zibo Yonghua Filters Manufacturing Co. the company. The main drafters of this standard. Wang Zhiwei, Li Jianguo, Luo Hongwei, Linan Lan, Peng Xiaogang, Yaodong Bin, Li Yonghua, Shi Xuwen. This standard replaces the standards previously issued as follows. --- GB/T 5923-1986. Automotive diesel fuel filter test method

1 Scope

This standard specifies the automotive diesel fuel filter (referred to as filter) performance test method, the test chamber so that the filter performance The test results are comparable. This standard applies to the nominal volume flow (or nominal volume flow) at 200L/h or less automotive diesel fuel filter. Rated Volume flow is greater than 200L/h cleaner can refer to use.
