Glossary of test modules

Hydraulic performance

Accuracy of displayed temperature

This module enables the temperature obtained in a particular position of the temperature control to be checked (for example, in the safety stop), following an adjustment from full cold and according to several sets of pressures.

Adjustment behavior

This module allows to measure the peaks, oscillations and temperature drifts during a variation of the temperature control regulation.

From a position corresponding to a T0 temperature (38 °C), the temperature control actuator performs a setting motion towards a T1 temperature (36 °C) and then repeats the T0 test (38 °C) at T2 (40 °C).

Checking preset temperatures

This module makes it possible to measure the temperature obtained at a particular position of the temperature control.

This module can be run several times during a faucet test (after several other test modules) in order to verify the constancy of the setting during the different test steps.

Efficiency of the stop

This module allows to check the temperature obtained in the safety stop position, after adjustment from full cold.

Energy saving

This module allows to check the flow of hot water obtained with a mechanical mixer when it is in "hard point" position, centered in rotation left/right. In this position there should be no hot water consumption.

Flow determination

This module makes it possible to carry out a measurement of the mixed flow of the faucet under pressures of servo-controlled supply of hot and cold water. The tap is automatically fixed in the fully open position by the flow actuator. The flow rate measurement is carried out over the whole temperature regulation range of the faucet by means of the temperature control actuator.

After each temperature setting, the software automatically calculates the average flow rate during a configurable pause.

Flow variations

This module allows to check the ability of a thermostatic valve to provide a constant mixed water temperature when adjusting its flow control.

The module measures the mixed water temperature obtained while the actuator automatically moves its flow control.

Hard point and flow in water-saving position

This module allows the mechanical mixers to measure the additional effort required to pass the hard spot and the flow obtained in the water-saving position. This saving position is defined according to the position of the hard point.

Inlet pressure variations

This module allows to check the ability of a thermostatic valve to provide a constant mixed water temperature despite sudden variations in supply pressures.

The module applies different sets of hot and cold pressures defined by the test standards and automatically calculates the peaks, variations and oscillations of the mixed water temperature for each set of pressure.

Inlet temperature variations

This module allows to check the ability of a thermostatic valve to provide a constant mixed water temperature despite sudden variations in supply temperatures.

The module applies different sets of hot and cold temperatures defined by the test standards and automatically calculates the peaks, variations and oscillations of the mixed water temperature for each set of temperature.

Security test - Antiscald

The test consists in characterizing the capacity of the thermostatic valve to protect the user against possible burning during an accidental cut-off of the cold water pressure. When the cold water supply is cut off, the thermostatic valve must close the mixed water outlet as soon as possible. The machine switches off the cold water supply solenoid valve, then measures the temperature and the mixed water flow and determines the recovered amount of water and then the change in the mixed water temperature after return of the water supplies (hysteresis).

Sensitivity/fidelity

This module allows to characterize the temperature regulation depending on the automatically applied motion by the actuator to the faucet temperature control  in the course of a back-and-forth motion between the hot and cold stops. The software automatically calculates the sensitivity which corresponds to the amplitude of the motion corresponding to a defined temperature range. And the fidelity that corresponds to the temperature difference obtained for the same position of the mixer according to the move direction.

Temperature overshoot when operating the diverter

This module is used to characterize the behavior of the temperature control of a thermostatic mixing valve when operating the bath/shower diverter.

Temperature peak when operating the diverter

This module makes it possible to measure the mixed water temperature peaks during the actuation of the diverter control (bath/shower).

Temperature peaks from atmosphere
Temperature peaks when changing the thermostatic element

This module allows to measure the mixed water temperature peaks during a change of output of mixed water, in the case where each of these outlets is equipped with its own thermostatic element.

Thermal break (initial draw)

This module allows to characterize the behavior of a thermostatic mixing valve during the first opening of the flow following a rest time.

This function enables the body of the faucet to be initially cooled down and then to open a flow and to measure the temperature peaks and the stabilization of the mixed temperature.

Endurance

Actuation cycles of diverters

This module allows cycling of the bath/shower diverter. At each cycle, the module checks the diverter for correct operation by automatically detecting the presence of water on each of the bath/shower outlets.

Actuation cycles of faucet head

This module allows to carry out endurancerotating movements on the temperature or flow control of a thermostatic mixing valve or on the controls of single faucets or mixers according to standards, with the opening percentage, speed, and the torque applied to the closure being set.

Actuation cycles of single-lever mixer

This module enables to carry out cycles of actuation of the single lever of a mechanical mixer according to the standards with adjustable speeds and time delays.

Endurance module actuation cycles single lever mixers

Inlet temperatures cycles

This module allows to set, for tests of endurance, cycles of cold water-cold water/hot water-hot water supply at an adjustable rate.

Motion cycles of swivel spouts

  This module allows to perform endurance mechanical cycles on faucet swivel spouts (kitchen taps).

Timed cycles

This module enables endurance cycles of the self closing faucets to be carried out by checking, at each cycle, the flow times obtained.

Sealing characteristics

Hydrodynamic sealing of 4 bar

This module allows to check that the faucet body does not leak during the flow with a controlled inlet pressure(detection of external leaks).

Hydrostatic sealing of 16 bar

This module makes it possible to check, when the faucet is closed, that there are no external or internal leaks when the supply pressures are set to 16 bar.

Hydrostatic sealing of 25 bar

This module makes it possible to check, when the faucet is closed, that there are no external or internal leaks when the supply pressures are set to 25 bar.

Hydrostatic sealing of 35 bar

This module makes it possible to check, when the faucet is closed, that there are no external or internal leaks when the supply pressures are set to 35 bar.

Sealing of diverters

This module allows to conduct the leakage test of the bath/shower diverters on the output by the diverter opposite to the controlled one.
