Testing of emitters and emitting pipes makes it possible to obtain the functional characteristics of these components, providing methods to assess conformity with established technical requirements and supplying the information needed for correct installation and field operation.

Tests
- Flow uniformity: the objective is to determine the coefficient of variation of emitters or emitting pipes to ensure compliance with applicable standards and therefore guarantee uniform water distribution in the field.
- Flow rate as a function of inlet pressure: the objective is to determine the flow rate of an emitter or emitting pipe as a function of inlet pressure, both for non-pressure-compensating and pressure-compensating devices.
- Discharge exponent: this parameter is obtained from the results of the previous tests and indicates the emitter’s stability with respect to pressure variations.
- Resistance to hydrostatic pressure at ambient temperature: the objective is to verify that emitters or emitting pipes withstand the test pressure without showing any signs of damage.
