标准摘要
[中文适用范围]： 本国际标准规定了在模块化和非模块化条件下使用梯形宽顶堰在明渠中进行稳流测量的方法。 考虑在矩形和梯形渠道中使用堰。7.6 和 8.6 中给出了堰的使用限制。 [外文原描述]： This International Standard specifies a method of steady-flow measurement in open channels using a trapezoidal broad-crested weir under modular and non-modular conditions. Consideration is given to the use of the weir in both rectangular and trapezoidal channels. Limitations to the use of the weir are given in 7.6 and 8.6.
