Agricultural irrigation equipment — Centre-pivot and moving lateral irrigation machines with sprayer or sprinkler nozzles — Determination of uniformity of water distribution

Specifies a method of measuring uniformity of water distribution in the field for the machines (not equipped with various corner application devices). The method of computing the coefficient of uniformity from the data produced is also laid down.
