This Saudi Standard applies to cord extension sets, rewirable and non rewirable, with earthing contact, with a rated voltage of 220 V having a rated current of 13 A or with a rated voltage of 127 V having a rated current of 15 A, intended for household and similar purposes, either indoors or outdoors. NOTE 1 Cord extension sets with earthing can accept plugs of class II equipments. This standard also applies to plugs incorporated in cord sets, to plugs and portable socket-outlets incorporated in cord extension sets and to plugs and socket-outlets which are a component of an appliance, unless otherwise stated in the standard for the relevant appliance. This Standard also applies to cord extension sets which are intended to be used in a cable reel and therefore they become cable reels with a detachable flexible cable. For the combination of the cord extension set and the reel requirements and tests of IEC 61242 have to be fulfilled in addition. This standard does not apply to – cord extension sets with means for reeling; – plugs, socket-outlets and couplers for industrial purposes; – appliance couplers; – plugs, fixed and portable socket-outlets for ELV; NOTE 2 ELV values are specified in IEC 60364-4-41. – fixed socket-outlets, automatic switches, etc. NOTE 3 Socket-outlets with pilot lights are allowed provided that pilot lights comply with the relevant standard, if any. Cord extension sets should be suitable for use at ambient temperatures not normally exceeding +45 °C, but their average over a period of 24h does not exceed +35 °C, with a lower limit of the ambient air temperature of -7 °C. NOTE 4 Socket-outlets complying with this standard are only suitable for incorporation in equipment in such a way and in such a place that it is unlikely that the surrounding temperature exceeds 35 °C. In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.
