We are pleased to update you a good news that Paneltek-Togen Terracotta System has passed the BS: 8414 part 2 fire performance test recently for our terracotta panel and its whole cladding system ! The terracotta panel is of Paneltek brand and the system is designed by Togen.
From this test, we can conclude that our terracotta and system has perfect performance when exposed to the fire. It is considered as one of the safest building materials.
It is a proud thing to be announced because BS: 8414 ranks one of the highest testing standards for fire performance of external cladding systems. The test duration is up to 60 minutes, and there are 5 main test performance criteria as below.
1.External Fire Spread
Failure due to external fire spread is deemed to have occurred if the temperature rise above Ts of any of the external thermocouples at level 2 exceeds 600 °C, for a period of at least 30 s, within 15 min of the start time, ts.
2.Internal Fire Spread
Failure due to internal fire spread is deemed to have occurred if the temperature rise above Ts of any of the internal thermocouples at level 2 exceeds 600 °C, for a period of at least 30 s, within 15 min of the start time, ts.
3.Visible Flaming
Failure of the system is deemed to have occurred if visible flaming, which exceeds the confines of the test rig either vertically or laterally during the full 60 minute test period, is observed. For the purposes of this clause, visible flaming is defined as a continuous flame which is observed for more than 60 seconds duration (i.e. not intermittent or glowing)
4.Mechanical Performance
Failure will be deemed to have occurred if there is collapse of the system or part thereof (at least 500 mm length and 200 g), flaming or not, onto the floor of the test facility outside the designated crib collapse zone, see note 1, within the duration of the full 60 minute test period.
5.Burning Debris and Pool Fires
Failure is deemed to occur if burning debris or a pool fire develops on the floor of the test facility, outside the designated crib collapse zone. Burning debris is defined as visible flaming for more than 60 seconds duration (i.e. not intermittent or glowing) within the duration of the full 60 minute test period.
