This part of IEC 61156 which is a sectional specification relates to IEC 61156-1:2002. The cables are specifically intended for riser wiring up to category 5 (class D) as defined and specified in ISO/IEC 11801:1995. This specification defines individually screened or unscreened pairs/quads cables, with or without overall common screen. When installed vertically extra length requirements may be applicable and are defined in the relevant specifications. These cables are suitable for the various communication systems for which the reference is given in the relevant detail specification. The cables covered by this sectional specification are intended to operate with voltages and currents normally adopted for communication systems. These cables should not be connected to low impedance sources, for example, the public mains electricity supply. The recommended temperature range during installation is 0 °C to +50 °C. The normal operating temperature range is –40 °C to +60 °C. The actual temperatures range shall be indicated in the relevant detail specification.
