EN 50306-1 specifies the general requirements applicable to the cables given EN 50306-2, EN 50306-3 and EN 50306-4. It includes the detailed requirements for S2 sheathing materials and other components called up in the separate parts. In particular EN 50306-1 specifies those requirements relating to fire safety which enable the cables to satisfy Hazard Level3 of EN 45545-1 and -2. These cables are rated for occasional thermal stresses causing ageing equivalent to continuous operational life at a temperature of 90 °C. For standard cables this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5000 h) thermal ageing indicating a 110 °C/20 000 h temperature index. Should the customer require lifetime predictions this should be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. EN 50306-1 has to be used in conjunction with one or more of the other parts of EN 50306.
