Meka cable support systems’ fire resistance
Meka Pro Oy tests its products regularly to ensure quality and safe cable support systems. The products have been tested as widely and with as several different installation ways as possible. The lat-est fire resistance tests have been made at SertPromTest test facili-ty in Moscow 2016 and at VTT in Finland during 2013 and 2014.
Used fire resistance test environments and methods have been complied according to the following standards:
• EN 1363-1• DIN 4102-12• GOST-R 30247.1• prTR 50658:2016
Standards include details regarding fire resistance test science and methodology. Common principles can be used within several test methods; however more precise details vary according to the test-ed element.
Fire resistant cable support systems
Most common cable support systems in fire resistant installations are cable trays, cable ladders and wire mesh trays.
Fire resistant cables must be installed separately from other ca-bles using distance or protection. Protection can be made for ex-ample with separation panels.
All fastenings in fire resistant cable support system installations must be made with fireproof components.
Fire resistant cables are marked with FRHF prefix, meaning Fire Resistant Halogen Free. Fire resistant cables can be recognized from orange or red jacket. The difference between fire resistant and normal construction cables is their minimized smoke for-mation and performance maintenance during fire circumstances.
