Construction checkpoints
Confirm conductor class and size, pair or triad count, insulation, CAM or ICAM screen, drain wires, bedding, SWA, sheath material, fire-performance requirement, marking and documentation.
BS5308 / PAS5308 Instrumentation Cables
Instrumentation cable selection
Choose BS5308 cable by Part, Type and screen
TEBAOFLEX manufactures BS5308 and PAS5308 instrumentation cable for 300/500 V analogue and digital signal circuits. Specify pairs or triads, then choose Part 1 polyethylene or Part 2 PVC insulation, Type 1 unarmoured or Type 2 steel wire armoured construction, and CAM collective or ICAM individual plus collective screening. These three choices are independent. The withdrawn BS 5308 and PAS 5308 names still appear in cable schedules, replacement enquiries and petrochemical projects, while BS EN 50288-7 is the current sectional specification. Confirm the required document, conductor size, screen arrangement, route, environmental protection and intrinsic-safety loop data before ordering.
BS5308 and PAS5308 construction routes
- Part 1 Type 1PE insulated, unarmoured pair or triad cable for protected fixed routes.
- Part 1 Type 2PE insulated cable with galvanised steel wire armour for mechanical protection.
- Part 2PVC insulated construction for general industrial signal and control routes.
- CAM or ICAMCollective screening, or individual pair and triad screens plus an overall screen.
Compare Part, Type, screen and formation
| Decision | Construction choices | Verify for this enquiry |
|---|---|---|
| Part selection | Part 1 PE or Part 2 PVC | Capacitance, temperature range and project material requirement |
| Type selection | Type 1 unarmoured or Type 2 SWA | Tray, conduit, burial, impact, crushing and gland arrangement |
| Screen selection | CAM collective or ICAM individual plus collective | Signal level, circuit segregation, earth reference and drain wires |
| Pair or triad formation | Pairs or triads, single or multi-unit | Unit count, conductor size, spare units and identification |

Provide the cable schedule or marking, required standard and agreed deviation, route conditions, intrinsic-safety duty, lengths, drum sizes, quantity, delivery destination and inspection scope.
Standard status: BSI records PAS 5308-1:2009 as withdrawn on 3 April 2024. BSI lists BS EN 50288-7:2005 as current and under review. A withdrawn designation may remain on a project schedule, but the governing document and any deviation should be agreed before manufacture.
