MODUK DEF STAN 61-12: PART 25: Wires, Cords and Cables Electrical Part 25: Wires and Cables Electrical Limited Fire Hazard, up to Conductor Size 10mm2 Cross Sectional Area

The cables shall be suitable for use on electric power and communications circuits with a potential not exceeding 600V AC RMS, 800V DC between cores, or between cores and the surrounding structure, or between cores and earthed screen(s) included in the cable, at frequencies up to 400Hz. The maximum cable conductor size is 10 mm² cross-sectional area.

The cables detailed herein use insulated cores complying with Tables 9 to 12 or Table 17 of Def Stan 61-12 (Part 18) type and the sheathing material complies with Def Stan 61-12 (Part 31). They present a limited fire hazard cable, producing limited levels of noxious fumes, smoke and corrosive products when burnt.

The materials used for cable constructions will give a service life exceeding 40,000 hours at a continuous conductor temperature of 85°C.

Users should be aware that only cables with Standard, Type 1 – pliable type cores are now included in this standard. The Type 2 - less pliable cored cable which were listed in previous issues have been removed.

Users should check that these cables are compatible with the terminations and connectors with which they are to be terminated, with particular reference to cable connector sizes and insulation diameters.

All requirements and tests specified in this Standard are applicable.
