Fire resistance
3 - Fire barrier test through a partition wall
Objective
To check a busbar trunking will not propagate a fire from one room to another by
crossing a fire barrier wall for 60, 120, 180, or 240 minutes.
As defined in standard EN 1366-3.
Method
The fire barrier busbar trunking section to be tested is placed in an oven which
executes a standardised temperature-time curve.
Result criteria
The specimen is considered to have passed the test if:
there are no flames behind the fire barrier,
there is no smoke or gas behind the fire barrier (not requested by the standard;
can appear as a remark in the test report),
the temperature rise of the casing behind the fire barrier does not exceed 180°C.
4 - Conservation of all circuits in fire conditions test
Objective
To check all the busbar trunking's electrical circuits are preserved in fire conditions.
As defined in standard DIN 4102 part 12.
Method
Its entire length inserted, the busbar trunking is taken as a specimen in an
insulating sheath.
Result criteria
The specimen is considered to have passed the test if:
conductor continuity is preserved,
there is no short-circuit between conductors.
