Introduction

This specification is based on the International Legal Organization (OIML) International Recommendation OIMLR21-2007 "Taxi Meter. measurement and technical requirements, test procedures and test report formats "(Taximeters. Metrologicaland technicalrequirements, testproceduresandtestreportformat), JJF 1015-2014 "metering Ordinary Specification of Apparatus Type Evaluation "and JJF 1016-2014" Guidelines for the Compilation of Outline of Measuring Instruments " Basis, combined with China's taxi meter industry status quo, JJG517-2009 "taxi meter" Appendix A "Valves type evaluation test method" to be revised. The main technical indicators are partially equivalent to international recommendations. This specification compared with JJG517-2009, in addition to editorial changes, the main technical changes are as follows. --- adjust the term "taxi meter", "meter constant k" and "mileage measurement sensor" to make it Meaning more clearly; --- adjust the "meter constant k" unit of measurement to make it consistent with the international recommendations; --- adjust the timing error, permanent clock error measurement performance requirements; --- deleted the seal location requirements; --- remove the wire color requirements; --- delete the contents related to the tax control function; --- adjust the contents of a single operation data storage and storage requirements; --- adjust the permanent clock error test method; - to adjust the environmental adaptability of the test requirements and measurement performance test methods; --- Added the contents of Chapter 9, "Providing the Number of Prototypes and How to Use the Prototype" - Added Chapter 10, "Test Methods, Test Conditions and Data Processing and Compliance Criteria for Test Projects" Content; - Added the contents of Chapter 11, "Measuring Instruments and Equipment Tables for Test Items" --- Added the contents of Appendix B "Type Evaluation Record Format". After the implementation of this type of evaluation outline, the original approved type without any or part of the evaluation. "Taxi meter type evaluation outline" of the previous version of the release. --- "Taxi Tax Control Validation Guiding Outline"; --- JJG517-2009 "Taxi Meter" Appendix A. Taxi type evaluation outline

1 Scope
