Behovet av sprinklerskydd ovan undertak med hänsyn till kablars brandklassificering

- Abstract
- This report analyses the need of sprinkler protection above suspended ceilings with regard to the fire classification of cables. The question formulation for this report is which ignition hazards can lead to a fire in cable ladders above suspended ceilings as well as how the fire classification of cables effect the need of sprinkler protection above suspended ceilings.
The main conclusions that have been made are that it is not legitimate to protect cables classified as B2ca or Cca with sprinkler systems due to their self-extinguishing behavior and the fact that these cables do not show any major heat release when burning. It is appropriate to protect cables classified as Dca or lower with sprinkler systems as they tend to develop...

The question formulation for this report is which ignition hazards can lead to a fire in cable ladders above suspended ceilings as well as how the fire classification of cables effect the need of sprinkler protection above suspended ceilings.
The main conclusions that have been made are that it is not legitimate to protect cables classified as B2ca or Cca with sprinkler systems due to their self-extinguishing behavior and the fact that these cables do not show any major heat release when burning. It is appropriate to protect cables classified as Dca or lower with sprinkler systems as they tend to develop higher heat release rates during fire in addition to a great spread of the fire. However, since there are cables classified as Dca that self-extinguishes after only a short length of cable damage, there is a possibility for the exception of sprinkler protection for certain cables classified as Dca.
