Sprinkler test<br />
General information<br />
Sprinkler fire-extinguishing systems in particular are used for<br />
protecting cable conduits and cable ducts. Here it is predominantly<br />
the cooling effect of the water on the surface of the fire<br />
which is exploited. Operation of the sprinkler for at least<br />
30 minutes should be assumed.<br />
Siemens has subjected its BD2A/BD2C busbar trunking systems<br />
to an extensive range of tests with sprinkler systems. Due<br />
to the absence of a mandatory standard or directive, the test was<br />
performed using a test setup which mirrored a practical application<br />
(see the sketch).<br />
Test results<br />
With the BD2A/BD2C busbar trunking system, the system with<br />
IP54 degree of protection was sprinkled in all fitted positions<br />
paying close consideration to the "VdS" guidelines for sprinkler<br />
systems. The insulation resistance was measured before and<br />
after sprinkling for 90 minutes, and a high voltage test according<br />
to EN 60439-2 was performed. This test was absolved successfully<br />
and indicated that the system could be operated immediately<br />
after sprinkling without any delays.<br />
