Shrinkage test on finished cable

Test Method: EN 60811-1-3
Requirements: Maximum shrinkage: 2%
Procedure: Test samples 450mm in length shall be taken from each wire. The insulation is then removed from either end to leave a length of insulation 300mm in total. The insulation is then suspended horizontally in an oven, by the bare conductor ends, at 120 ± 2°C for 1 hour then removed and placed at room temperature to cool down, this cycle is then repeated 5 times. At the end of the 5 cycles the insulation is measured to determine the shrinkage.
