Airport terminal wiring
Specify IS 17048:2018 LSZH in occupied terminal areas where the project specification limits halogen acid gas to 0.5%. IS 17048:2018 also requires light transmittance of at least 70% through the smoke.

Airport & aviation cable — common questions.
Specification questions raised by airport procurement teams and aviation MEP consultants.
Which cable type is specified for airport terminal occupied areas?
NBC 2016 does not assign a cable type to airport terminals, and IS 17048:2018 is not cited in NBC 2016. NBC 2016 Part 8/Sec 2 cl. 5.3.7.1 states that it is desirable to use flame retardant cables and wires, and that FR-LSH cable may be considered. Specify IS 17048:2018 LSZH in terminal areas where the project specification limits halogen acid gas to 0.5%.
IS 17048:2018 limits LSZH to halogen acid gas ≤ 0.5% and requires light transmittance ≥ 70% and Oxygen Index ≥ 31.
What flame-spread evidence do airport tenders typically require for tray installations?
Bunched cable installations on airport trays typically require IEC 60332-3-24:2018 Category C evidence — flame-spread limit 1.5 L/m fuel — submitted alongside single-cable test data per IEC 60332-1-2:2004. Category C is the appropriate level for grouped low-voltage cables in dense terminal trays.
National Cables supplies IS 17048:2018 type-test documentation (smoke transmittance, halogen emission, IEC 60332-1-2 single-cable flame test) with the BIS licence reference (CM/L-8800227819); state bunched-test (IEC 60332-3-24) requirements at the enquiry stage.
Which cable applies to BMS, fire alarm, and HVAC control circuits in airport buildings?
BMS, fire alarm, and HVAC control circuits use screened multicore control cable based on IS 694:2010 Class 5 flexible — typically with aluminium foil + tinned drain-wire for EMI shielding where the discipline drawings call for it.
Class 5 fine-strand construction handles repeated bending during panel installation; the screen prevents EMI coupling with sensitive 4–20 mA loops, RTD inputs, and Modbus / BACnet signal lines that share trays with VFD and high-current power feeders. Specify foil + drain with single-point screen earthing per the EMC plan.
Why is 1100 V-class IS 694:2010 specified rather than 600/1000 V cable?
Airport equipment rooms and panel wiring use IS 694:2010 1100 V-class insulation rather than 600/1000 V cable to provide margin against motor-start surges and switching transients common in aviation infrastructure (jet bridges, baggage conveyors, HVAC AHU motors).
The same 1100 V production line manufactures the export H07Z1-K (EN 50525-3-31) LSZH and H07V-K (IEC 60227-3) single-core wire — enabling consistent specification on cross-border terminal projects.
Is National Cables' wire eligible for international airport tenders?
Yes. H07Z1-K (EN 50525-3-31) LSZH single-core and H07V-K (IEC 60227-3) PVC single-core are produced from the same BIS-certified IS 17048:2018 and IS 694:2010 production lines and carry full international type-test documentation.
For airport projects in GCC, African, and European markets, these harmonised designations meet local specification practice without requiring cable redesign. Test certificates and material declarations are issued in tender-ready format.
