Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Machinery Industry Federation. This standard by the national industrial process measurement and control Standardization Technical Committee (SAC/TC124) centralized. This standard was drafted. Shanghai Industrial Automation Instrumentation Institute, Naval Air Station instrumental, Fujian on the Run Precision Instrument Co., Shanghai Weier Tai Industrial Automation Co., Ltd., CNOOC (China) Co., Ltd., Shanghai Automation Instrumentation System Inspection and Testing Institute.

1 Scope

GB/T 29247-2012 is the common test method behind the numbers on an industrial instrument's data sheet. A transmitter's accuracy, its dead band, its response to a change in ambient temperature or in supply voltage - each of these is a claim, and a claim is only comparable between two manufacturers if both measured it the same way. This standard fixes that way. It specifies the test equipment, the test configuration, the test procedures and the content of the test report for industrial process measurement and control instruments in general, covering the performance characteristics that recur across instrument types: reference accuracy, dead band and hysteresis, the influence of ambient temperature, input impedance, frequency response, and the effect of changes in supply voltage and frequency. It applies to evaluating instrument performance under normal conditions of use; instruments subject to additional requirements under special working conditions fall outside it. Under ICS 25.040.40 and CCS N10, it is the reference for instrument makers writing specifications, for laboratories verifying them, and for the process industries that have to compare competing equipment on equal terms.

This standard specifies the test methods for general industrial automation instruments, including test equipment, the test configuration, test procedures and test reports. This standard applies to work under normal conditions of use of industrial automation instruments and apparatus (hereinafter referred to as the instrument) performance evaluation. This standard does not apply to the test under special working conditions of the instrument of additional requirements.
