What is the minumum insulation resistance value for 600V power cables tested at 500V and 1000V ?

[bdn2004]

We are supposed to comply with ICEA standards for meggering power cables.
We don't want to have to purchase the standard if we don't have to.

What voltage and type of cables?

 

[bdn2004]

Mostly 600v cables operating at 480v, all the cables route in cable tray, and conduit, some of them are also routed through upen trenches and duct banks. All are tray rated with different types of insulation mostly RHW.
