Classification of German Fireproof Cable Tray Applications
The DIN Standard 4102 part 12 defines the requirements and testing method for fire resistance of electric cable support sys-tems required to maintain its integrity. The standard, limited to 1KV, specifies 3 categories of functional maintenance as fol-lows: E30, E60 and E90. Fire protection technology plays a central role in ensuring the safety of people and buildings. In the event of a fire, it is necessary to maintain the functionality of certain electrical installations, such as. The UL 1257 testing standard evaluates the performance of cable tray and conduit assemblies in a fire environment by subjecting them to various temperature conditions. This includes: Filling the assembly with combustible material to simulate real-world exposureucts; however, as an alternative DIN. Until the European standard is published, VERGOKAN uses, the DIN 4102-12 Standard to test and certify the preservation of functionality of its installations.
