Foreword

This corresponds to the standard IEC 61023.2007 "Maritime navigation and radio communication equipment and systems ship speed and distance measuring equipment" And IEC 61023.2007 non-equivalent. This standard replaces GB/T 4301-1992 "for marine electromagnetic drive general technical conditions." This standard compared with GB/T 4301-1992 The main changes are as follows. --- Standard name changed to "for marine electromagnetic drive device." --- Sea increased measurement error. According to the development of sensor technology, it was provided for the use of different types of electromagnetic sensors taximeter Offshore instrument measurement error. --- Clearly defines the reliability index. --- Standard "precision" unified "accuracy" or "error." --- Increasing the water spray test. --- Increasing the provision of full-scale track time. --- Modified voyage solver accuracy of calculation formula. The standard proposed by China Shipbuilding Industry Corporation seventh Research Institute of Jiujiang ○ seven divisions. This standard by the National Standardization Technical Committee boat ocean nautical instruments division Technical Committee. This standard was drafted. China Shipbuilding Industry Corporation. The main drafters of this standard. Xie Ying, Xinhui Zhen, Du recipe books, Ding Jianjun. This standard replaces the standards previously issued as follows. --- GB 4301-1984, GB/T 4301-1992. For marine electromagnetic drive device
