Standard Insulation Resistance Test Procedure of Cables

I came into an argument with one of my colleagues,

who said that in IR test of cables the cable's conductors should be shorted at one end and at another end the supply voltage should be given. I told that it should be open.

When I searched for sources on the internet some videos show that it should be shorted and some opened.

Kindly give a clear view of this...
 
You are getting into the electrical testing methods and standards. No simple answers, but the simplest approach is to contact the various tester suppliers, as they will have summary guidelines.

Generally, the tests you run depends on what you are testing for (continuity, breakdown strength, signal wiring, power wiring, etc.), the voltages involved, and temperature ratings. Elevation and ambient conditions also play a role.
