EN 50200 Method of test for resistance to fire of unprotected small cables for use in emergency circuits

Test set-up
The cable (maximum 20 mm diameter) is fixed on a positioning board and flame is applied from the front. The positioning board is subjected to knocks every 15 minutes during the burn period.

Flame temperature
842 °C

Test duration
90 minutes

Compliance criterion
For cable and conductors with voltage rated up to 600 /1000 V: There must be no short ■ circuit between the conductors and no open phase.
For data and communications cable without voltage rating: There must be no short ■ circuit between the conductors and no open phase.
For fiber optic cables: The increase in attenuation must not exceed the figure specified ■ in the respective design standards.
