Introduction

This specification is based on GB/T 778.1 ~ 3-2007 "closed conduits Measurement of water flow cold potable water And hot water ", the International Organization of Legal Metrology (OIML) International Recommendation OIMLR49-1.2013 (E)" measure The amount of potable water meter cold and hot water - Part 1. metrological and technical requirements "and OIMLR49-2.2013 (E) "Measurement of potable cold water and hot water - Part 2. Test methods" as the basis for the preparation, combined with our hot water Table manufacturing industry status and use of the "water table Pattern Evaluation Outline" JJG686-2006 be revised Appendix A of. The main technical indicators and national equivalents. This specification Press JJF 1016-2014 "appliance type evaluation outline guidelines for the preparation of measurement" Writing. This specification compared with the type of evaluation outline JJG686-2006 Appendix A, the main technical changes are as follows. --- In outline the scope of the re-provision. In addition to mechanical water table, the increase based on electromagnetic or electronic Working principle water table; water table by the maximum operating temperature of 180 ℃ to 130 ℃, and is represented by the temperature class; --- Press JJF 1016, experimental prototype to increase the type approval mark and number of requirements in terms of signs; Flow characteristics --- water table by Q1, Q2, Q3, Q4 OK, replace the original characteristics of the traffic sign; all with hot Expression meter performance and error test related parameters according to the flow of new features; --- Water table by Q3 (in m3/h units) and ratios flag Q3/Q1, Q2/Q1, and the provisions of the Department of The number of columns, an alternative expression of the original code and measurement meter level A, B, C, D of; --- Type of pilot projects to increase the influence of test temperature, water temperature overload test, reverse flow experiment, the flow interference test Inspection, static magnetic field test; with electronic devices for water table increases the functionality test, climate test, power supply variation test And electromagnetic environmental testing; measuring unit for exchangeable water table, increasing the metering unit replacement pilot projects; --- For Q3 > 16m3/h water table, reducing the durability test time; --- Increased Chapter 10, "Test methods and conditions as well as data processing and acceptance criteria of the pilot project," the content; --- Increased determination method selection series, complementing the various projects to test prototypes quantity requirements; --- Added Appendix A "record format type evaluation" of the content; The previous versions of this specification published case. --- JJG686-2006 "water table" in Appendix A.
