The designations remain in wide use in project specifications, but neither is current. The current document covering these cables is BS EN 50288-7:2005.

Polyethylene insulated constructions are commonly rated \u221230\u00a0\u00b0C to +75\u00a0\u00b0C for fixed installation and PVC insulated constructions \u221220\u00a0\u00b0C to +65\u00a0\u00b0C. Confirm the figure for the specific build.\r\n\r\nIntrinsic safety\r\nThese constructions are designed to form part of an intrinsically safe system, and a blue sheath is the convention used to identify intrinsically safe circuits. Sheath colour does not by itself make a loop intrinsically safe: the cable inductance and capacitance per unit length must be checked against the permitted values for the complete loop. Request those parameters with the enquiry.\r\n\r\nWhat to send with an enquiry\r\n\r\nPart, Type and screening arrangement, or the construction described in full\r\nConductor class and cross-sectional area\r\nNumber of pairs or triads\r\nRoute conditions: buried, tray or trunking, ambient range, chemical exposure\r\nWhether the loop is intrinsically safe\r\nStandard to appear on the drum and in documentation, and any deviation already agreed\r\nLengths, drum or coil, marking and packaging\r\n\r\nMinimum order quantity is 50\u00a0m for standard and customised constructions alike, and lead time runs from 7 to 45 working days depending on product type, material position and the extent of customisation, as of August 2026.
