Flush-Test

Flush tank test bench

The Flush-Test validates the compliance of toilet cisterns with the
NF EN 14055 standard. It measures the volume, flow rate and impact force of the water,
while ensuring closed-loop recycling. Its modular frame and PC control system
guarantee flexible adaptation to the different cisterns being tested.

Main functions

The Flush-Test evaluates cistern performance by simulating
real-world operating conditions. It provides precise control of hydraulic
parameters to guarantee compliance with standards.

Key features :

  • Accurate measurement of the volume of water flushed with each flush
  • Testing different hunting levels
  • Simulation of repeated cycles
  • Measurement of the impact force of discharged water
  • Software interface with result tracking and analysis

Operating mode

The Flush Test replicates the actual conditions of use of toilet cisterns to verify their compliance and reliability.

Tank installation

  • Securing the tank to the bench with connection to the supply and drain
  • Spacing adjustment for tank mounting
  • Height adjustment of the tank
  • Adjusting the flush activation system
  • Impact force sensor adjustment
  • Hydraulic connection

Test configuration: each test is automatic and configurable.

Test procedure:

  • Measurement of flush volume and residual volume
  • Flow measurement
  • Measurement of the impact force of discharged water
  • Overflow level measurement

Results analysis: Real-time visualisation and data export for validation.

Bench developed to meet this standard:
