ISO 1100-2:2010规定了测量站水位流量关系的确定方法。需要足够数量的流量测量，以及相应的水位测量，以定义与ISO 1100-2要求精度的水位流量关系。考虑了稳定和不稳定河道，包括对位移控制、可变回水和滞后对水位-流量关系的影响的简要描述。未详细描述双规站、超声波速度测量站、电磁速度测量站和其他复杂额定曲线的流量测定方法。ISO 1100中列出的其他国际标准、技术规范和技术报告分别描述了这些类型的额定曲线-2.

ISO 1100-2:2010 specifies methods of determining the stage-discharge relationship for a gauging station. A sufficient number of discharge measurements, complete with corresponding stage measurements, are required to define a stage-discharge relationship to the accuracy required by ISO 1100-2.Stable and unstable channels are considered, including brief descriptions of the effects on the stage-discharge relationship of shifting controls, variable backwater and hysteresis. Methods of determining discharge for twin-gauge stations, ultrasonic velocity-measurement stations, electromagnetic velocity-measurement stations and other complex rating curves are not described in detail. These types of rating curve are described separately in other International Standards, Technical Specifications and Technical Reports, which are listed in ISO 1100-2.
