I am proceeding the DC sheath test as per IEC9 standard.
but unfortunately the standard is not specifying any limit value or base value or safe value.
The Ohmic valeu is only a indication of healthiness and reference-the real test is that 10KV DC should be able to withstand for 5 minutes and that is the test for jacket/sheath integrity test.-off course as a ref you have to take values of IR also after HV test.
