Table 31. Table for ULTRAFLOW
including suggested test points, test durations and test quantities.
The suggested test parameters are based on EN 1434-5 and q
p
:q
i
100:1.
The test set-ups have been selected on the basis of the following requirements:
•
Minimum test duration of 3 minutes
•
Water volumes at q
i
and 0.1 x q
p
of minimum 10 % of the water volume per hour
•
Water volume at 0.1 x q
p
corresponding to minimum 1000 pulses
•
Water volume at q
i
corresponding to minimum 500 pulses
These suggested test points can be optimized for the test benches as well as for the test purpose.
