6 静态限界检查试验 Inspection Test of Static Gauge
6.1 静态限界检查试验 Inspection Test of Static Gauge
检查动车组外形尺寸，以确保动车组各部分结构在任何使用条件下互相不出现实质性的妨碍，同时满足GB146.1-83《标准轨距铁路机车车辆限界》及铁路技术管理规程（速度大于200km/h车辆限界）的要求。
Check the overall dimension of MU to guarantee the structures of all parts of MU from substantial obstacles under all using conditions. Meanwhile, it should comply with the requirements of GB146.1-83 “Rolling Stock Gauge for Standard Gauge Railways” and Technical Management Regulation of Railway (vehicle gauge with the speed of more than 200km/h).
仅进行头车的限界试验，其余车型限界试验BST公司已申请试验免除。
