Back in the day testing was not carried out much in all honesty, most sparkies only carried a megger, basic voltage test and a earth loop impedance tester if you were lucky.IMO with the amount of testing today VIR cables would not take too much pulling about, especially at the accessories connected to the stuff just fell apart in your hands. Hopefully most of that has been relaced but I bet there is some still in service.
