Foreword

This standard replaces GB/T 6146-1985 "precision resistance alloys resistivity test methods." This standard compared with GB/T 6146-1985, in addition to editing the text on the revised format, the main difference is. --- In the scope clearly stated reference temperature of 20 ℃; --- Resistivity units of μΩ · m; --- Deleted the preparation of samples in Table 1, the contents of which are specified in the relevant provisions; --- The resistance test equipment to ensure accurate measurement of the provisions of 0.001% change in resistance of the sample; --- Specifies the test specimens having simple cross-section and does not have a simple cross-section sample size measuring instruments. The standard proposed by the Machinery Industry Federation. The standard instrument functional materials by the National Standardization Technical Committee (SAC/TC419) centralized. This standard is drafted by. Chongqing Instrument Materials Research Institute. Participated in the drafting of this standard. Changzhou Lucheng Albert Alloy Factory, Jiangsu Huaxin Alloy Co., Ltd., Shaoxing Chunhui Automation Instrumentation Co., The company, the Liaoning Provincial Institute of Metrology, Texas Qunli Alloy Material Co., Ltd. The main drafters of this standard. WU Shan, Chen Lixin, Ho Ying-lun, Wang Bowei, Yuan Hua Qin, Zou, Dong Liang, tension group. This standard replaces the previous version of the standard release of case. --- GB/T 6146-1985. Precision resistance alloys Resistivity Test Method
