and reliable when properly used,-to state the characteristics, performance, and construction requirements directly orindirectly bearing on safety,-to specify methods for checking conformity with these requirements.EN 50264, which covers a range of cables rated at up to 3,6/6 kV with conductor sizes1,0 mm2 up to 400 mm2, is divided into 3 parts:Part 1: General requirements;Part 2: Single core cables;Part 3: Multicore cables.These cables are intended for a limited number of applications. Further information onthese applications is given in the guide to use (EN 50355 – under development).Special test methods referred to in EN 50264 are given in EN 50305.A separate European Standard, EN 50306 covers cables for similar applications but withthin wall insulation, restricted to 300 V rating and a maximum conductor size of 2,5 mm2.SIST EN 50264-1:2003
- 5 -EN 50264-1:20021ScopePart 1 of EN 50264 specifies the general requirements applicable to the cables given inpart 2 and part 3 of EN 50264. It includes the detailed requirements for the insulating andsheathing materials and other components called up in the separate parts.
In particularEN 50264-1 specifies those requirements relating to fire safety which enable the cables tosatisfy Hazard Levels 2, 3 and 4 of EN 45545-1.NOTE 1
Requirements for the emission of smoke and gases are not specified for Hazard Level 1 ofEN 45545-1.NOTE 2
EN 45545-1 is still under development and should be consulted.Based on proven experience and reliability over many years these cables are rated foroccasional thermal stresses causing ageing equivalent to continuous operational life at atemperature of 90 oC. The maximum temperature for short circuit conditions is 200 oC basedon a duration of 5 seconds.This part 1 should be used in conjunction with the other parts of EN 50264.2Normative referencesThis European Standard incorporates by dated or undated reference, provisions from otherpublications.

These tests are of such a nature that, after they havebeen made, they need not be repeated unless changes are made in the cable materials,design or type of manufacturing process which might change the performancecharacteristics3.6sample tests (Symbol S)tests made on samples of completed cable, or components taken from a completed cableadequate to verify that the finished product meets the design specification3.7routine tests (Symbol R)tests made on all complete cable lengths to demonstrate their integrity4Rated voltageThe rated voltage of a cable is the reference voltage for which the cable is designed, andwhich serves to define the electrical tests.The rated voltage V is expressed by the combination of the following values (in volts):Uo/U(Um)Uo is the r.m.s. value between any insulated conductor and earth, i.e. metalcovering of the cable or the surrounding medium, e.g.Uo = 600 V;Uis the r.m.s. value between any two phase-conductors of a multicore cableor of a system of single-core cables, e.g. U = 1 000 V;Umis the maximum r.m.s. value of the "highest system voltage" for which theequipment may be used, e.g.Um = 1 200 V.SIST EN 50264-1:2003
