Introduction

This specification is based on the national standard GB/T 6968-2011 "diaphragm gas meter", the International Organization of Legal Metrology (OIML) International Recommendation R137-1 Close Current Situation diaphragm gas meter industry for JJG577-2005 version A "type evaluation test program" into the appendix Line revision. The main technical indicators and national standards equivalent to international recommendations. Compared with this specification version JJG577-2005 Appendix A "type evaluation test program", the main technical change as follows. --- Cancel the measurement level, using the level of accuracy of representation; --- Modify the counter technical requirements; --- Modify the parameters of the gas meter flow range; --- Modify the test environment requirements; --- Cancel the torque effect on performance requirements; --- Cancel the standard deviation of the test; --- In place of the electromechanical conversion conversion error; --- Changed the time indication error test minimum ventilation requirements; --- Increased anti-reverse function tests; --- Increasing the temperature of the aptitude test; --- Increasing the control valve leakage test; --- Increased traffic overload test. JJG577-2005 Appendix A of the previously issued as follows. --- JJG577-1994 "diaphragm gas meter" Appendix 2 "full-performance test items the gas meter, apparatus and law"; --- JJF 1086-2002 "diaphragm gas meter stereotypes qualification program."
