Constructions that meet it
- Steel or aramid support members: changes the cable's layers. Steel or aramid support members inside the cable (steel rope, aramid). Drawbacks: Lift cables; larger, heavier.
- Galvanised steel wire armour: changes the cable's layers. Steel wire armour (double wire armour for deep shafts) (galvanised steel). Drawbacks: Mine shafts; heavy.
- Aramid yarn strength layer: changes the cable's layers. Aramid yarn strength layer (fibre cables) (aramid).

Tests
No international test method: specifications state this in words. Tests that exist:
- EN 50214 (lift cables): construction; free suspension length is the maker's. Pass: Datwyler: unsupported 45 m, fibre or steel supported 80 m, steel supported 220 m free suspension
How specifications state it
Specified as a hanging length, a pulling force or 'suitable for vertical installation'; maker ratings.
Where it is asked for
- lift and hoist cables
- mine shafts
- high-rise risers
- boreholes
