In the paper are presented practical knowledges and experiences from quality parameters measuring methods of microirrigation technologies. Data and results of irrigation water distribution unifomity was obtained by using of microsprinkler type WATERBIRD III - AA. Testing methods and testing methodology was used according technical standards STN ISO 7749-1J, STN ISO 7749-2 and STN ISO 8026, where are strictly defined all technical test conditions and test methods, clasification classes, terminology etc. Basic result of measured parameters of above mentioned microsprinkler are presented. Evaluation and classification of microsprinkler in potential spacing was authors contribution to the application field of mentioned standards. Quality parameters for spacing using of microsprinklers are more usable than individual microsprinkler parameters as it is defined in STN ISO standards. There is not recommended application spacing more than 6 x 6 for measured and evaluated microsprinkler due to the fact of nonacceptable Cu value, which is less 78% for pressure 200 kPa or 75% for pressure 150 kPa
