Introduction

This outline is based on the national standard GB/T 19237-2003 "car with compressed natural gas filling machine" and the international rule of law Metrology (OIML) International Recommendation R139.2007 (E) "vehicle compressed gaseous fuel measuring systems" (Com- pressedgaseousfuelmeasuringsystemsforvehicles) as a technical basis, combined with our filling machines Industry status quo, to JJG996-2005 "CNG refueling machine" A "type of evaluation items and test methods" Appendix Subject to revisions. With international recommendations on the main technical indicators, national equivalents. The Memorandum and JJG996-2005 in A "type of evaluation items and test methods" Compared appendix, the main technical change Of the following. --- Increased by large, medium and small flow filling machine terminology; --- Modify the nameplate of measuring instruments, increasing the minimum content to be measured; --- Modified with a pressure limiting protection structure and working principle function filling machine; --- Increase the structure and working principle without pressure limiting protection filling machine; --- Increasing the flow of medium and small filling machine is the smallest measurement requirements; --- Modify the voltage limiting protection pressure range; --- Cancel the solenoid valve off test; --- Modify the type evaluation test specification standard equipment; --- Modify the quality of the Gas Flow Standard device parameters associated equipment; --- An increase of non-reference conditions and reference conditions during pattern evaluation tests; --- Modify the measurement accuracy test (flow range, data processing, etc.); --- Modified test measured minimum number of measurements and data processing; --- Modified durability test methods and requirements; --- Modify the power adaptability test; --- Modify the original record format type evaluation.
