6.8 Sprinkler test
Sprinkler systems are used in buildings for fire protection. Sprinkler systems are
automatic fire extinguishing systems. Their function is to detect outbreaks of fire
by early detection and to extinguish them as quickly as possible by direct
sprinkler irrigation.
During the extinguishing process, sprinkler irrigation of at least 30 minutes is to
be assumed.
The unibar H busbar system has been subjected to a sprinkler test.
In the absence of a binding standard, the test was based on a practical test
structure (see drawing in German).
Test sequence
First, 3.5 kV/30 s AC voltage was used to test according to EN 614391, 10.9.
The busbar was then sprinkled with 300 l/min for 15 minutes, after 15 minutes
another 35 minutes with 115 l/min.
Result
The final AC voltage test with 3.5 kV/30 s according to EN 614391, 10.9 was
passed.
