The need for a rational use of water and supply of food for a growing world population have led to the development of research in the area of irrigation systems. Thus, some irrigation systems which join efficiency with low cost of material have been developed. Although some technical characteristics are provided by the manufacturers, tests are required to verify functioning of the system and uniformity of water distribution. Continuous research on uniformity, characteristics of the materials and design of water distribution systems is essential for system improvement. Therefore, the objective of this work was to evaluate the CV (manufacturer's coefficient of variation) of Amanco microsprinkler (1.0 mm light green nipple) using bench testing in the laboratory of Irrigation at UNESP - FCA campus of Botucatu-SP. Twenty-five microsprinklers in a sequential design were used in the tests. Three flow systems were tested as follows: a Coil system based on serial connected pipes; a Lateral system, the most common system in which secondary lines are fed by a main line; and a Mesh system used in the urban water supply. The results showed that 4.17% CVf met the production standards and the Lateral and Mesh systems were similar regarding outflow using bench testing. The Mesh system presented the highest mean value of outflow and the lowest range of variation.

The paper analyses the application of the AHP method together with the attach A of ISO 9004:2000 in order to evaluate the performance of two industrial organizations, both possessing quality management systems with ISO 9001:2000 certifications, based on the specific requirements of quality, environment, occupational health and management systems. The evaluated organizations were a government-owned company from the science and technology sector that works in the nuclear area, and a private company that works in the automotive and railroad area. The open software Web-Hipre version 1.22 from Helsinki University of Technology, Finland, was used. The results demonstrated that the AHP method together with the attach A of ISO 9004:2000 is adequate to evaluate organizational performances. Both organizations presented similar performance levels.
