Résumé :

Tests and certifications for trickle irrigation by the National Irrigation Laboratory. The services normally carried out, by Pisa National Irrigation Laboratory, to test trickle irrigation equipments are illustrated. The significance, the limits and the interpretation of Laboratory's certifications are briefly pointed out and the use of the certified parameters for the system design is showed too. In detail are described the tests to measure the following characteristics : average nominal emitter discharge and its manufacturer's coefficient of variations; emitter discharge versus pressure relationship; friction losses through emitters and emitter connections; tables and diagrams to design horizontal and sloping laterals; working tests of maximum 200 m long laterals; friction losses versus flow rate relationships of pipes, hoses fittings, valves and filters; emission uniformity of submain units.
