第四版CGA V-10《高压气体拖车连接》增加了高压气体拖车连接的额定压力。由于修改后的额定值可能导致气体拖车连接处的供气压力增加，因此本安全公告旨在为用户提供下游设备安全运行应遵循的最低预防措施。

The 4th edition of CGA V-10, High Pressure Gas Trailer Connections, increased the pressure rating for high pressure gas trailer connections. Because the modified ratings could result in an increase in the supply pressure at the gas trailer connection, this safety bulletin was developed to provide users with the minimum precautions that should be followed for the safe operation of downstream equipment.
