Working life span of twin; and twin & earth cables.

Sparkingchip:

We have not had a discussion lately about the anticipated working life span of PVC insulated twin; and twin & earth cables lately.


Given that many installations have PVC insulated twin; and twin & earth cables that are now over fifty five years old if we issue a satisfactory EICR with a recommendation to retest after five years the cable will actually be over sixty years old by the date the retest is due.


How much consideration do you give to putting in writing that you consider that sixty year old will still be okay to use?

I will consider after done with several testing including the life. span of PVC. If not, write in KIV.
