Abstract : The International Network of Irrigation Testing Laboratories INITL undertook a sprinkler intercomparison testing exercise to generate data for an objective comparison of the performances of the different facilities and identify opportunities for further improvements.Three impact sprinklers were tested in four laboratories in accordance with established standards. The plots of flow rate-pressure profiles were found to be consistent, and correlated to those obtained from previous studies. Although there were slight variations in the measured flow ratedata, the mean flow rates at each pressure level were the same for the three sprinklers, and the shapes of the radial distribution profiles were similar. The deviations of reconstituted flow rates from the measured of at least two tests in each facility were found to exceed the recommendedlimit. The sprinkler software developed by INITL was found to have a good correlation with a related commercial softwareprogram.
