Our full test range

Lamifil’s leading accredited in-house lab offers mechanical and electrical test solutions for aluminium and copper (alloy) conductors, contact wires, fittings and specialty wires. Discover our full range of tests here per segment.

Our lab offers a comprehensive range of accredited and non-accredited tests for overhead conductors according to standards including EN50182, IEC61089 and IEC61395. Our key offering of accredited tests includes the breaking load test, stress strain test, creep test, sag tension/temperature test, axial impact test and heat cycle test.

If needed, a cooperation with an external partner can be set up to allow for the most complete package of testing.

Specialised in copper and copper alloy wires for railway applications, our lab masters a number of fundamental tests to assess their mechanical and electrical properties and performance. The main tests requested by our customers are the creep test for contact wires and the mechanical fatigue test for dropper wires.

If needed, a cooperation with an external partner can be set up to allow for the most complete package of testing.
