The resistance-to-fire performance is measured as follows: 15, 30, 60, 90 and 120 minutes of operation in a standardised fire condition at European Level (CENELEC) and equivalent international (IEC). Now-a-days builders are gradually shifting to Fire Retardant category of cables to mitigate the risk of fire. It withstands high temperatures, temperature fluctuations, and humidity and moisture exposure without expanding or contracting. It has been answered by BASEC (Theme - Cable, Wiring and Wiring Accessories): SWA cable (BS 6724) is not fire resistant. Each with independent third party certification a brand you can trust. Flame Retardant 4 can also be machined, making it ideal for use in mass production. Cable with a PVC insulation or sheathing is flame retardant, which is an important consideration for electric cables in most applications. With new developments in wire and cable technology and recent changes in the NEC, a variety of new products have become available. 90 percent of the fires are electrical fires, mainly caused by a Defective Electric Circuit (DEC). Some international agencies like BASEC, UL, CE, etc also certifies the fire safety requirement of cables. FR4 also features a high strength-to-weight ratio and high hardness, ensuring the material will not break easily under load or during machining. Fire, Safety and Security; Electrical Heating, Ventilation & Control; Installation Tips; Lighting; Power; Regulation and Legislation; . SV: No doubt PVC has more flame resistance as compared to PE, but PE has much better electric properties as insulation.
