The EU cable CPR regulation EN50575 standard not only requires the vertical spread of flame for a single insulated wire and cable, but also requires bundle burning. The height of spread is required, and clear requirements are made for the smoke and heat generated during the combustion process. Additionally, clear requirements are made for the halogen content of wires and cables to avoid the release of acidic gases that can cause harm to human mucous membranes in fires. The above requirements can effectively reduce the harm to human health caused by the burning of wires and cables in a fire.
Main testing items and standards for CPR certification of optical cables
The European Union EN13501-6 standard specifies the fire rating requirements for building products, building components, and equipment. Among them, the fire rating of power cables, optical cables, network cables, and other cables is evaluated according to EN13501-6. The main standards for EN13501-6 fire rating testing are as follows:
EN ISO 1716: Total Heat of Combustion Test
EN 60332-1-2: Vertical flame propagation test
EN 50399: Heat release and smoke emission testing
EN 61034-2: Combustion smoke concentration test
EN 60754-2: Acidity testing of gases released during combustion
