Building wires and cables are evaluated according to EN13501-6 Standard Test and fire rating. The European Union market requires a minimum rating of class Dca or above for the fireproof grade of building wire and cable as the minimum requirement. According to the heat release rate of wire and cable and the length of combustion destruction, the EN13501-6 standard divides the flame protection of cables into seven grades, namely, EN13501-6, Aca, B1ca, B2ca, Cca, Dca, Eca and Fca, these seven grades. Nanjing SMART company to share wire and cable EN13501-6 fire rating, Dca level testing standards and data requirements. Tel: +86 25-8658 3475.
