SY Cable containment

I really cannot understand why SY or YY cables are not acceptable to BS7671. We used to use miles of the stuff in heavy industry. It's odd that the Bodies are only too quick to 'harmonise' with foreign standards, even the dreaded and suspect AFDDs from the USA, yet SY & YY seem to be orphans who have been left out in the cold.

Arctic cable is quite often left out in the cold ;)

Because it doesn't actually neet any UK or harmonised standard.  Once you start allowing non-standard cable to be used, how do you define what's acceptable?

All it would take is for the manufacturers to make a cable constructional standard for CY, SY and YY, and many of the problems would be resolved ... all that we would have to do is make sure we pick power cables for power wiring, not auxiliary cable (sadly, another issue is because a lot of the products have, in the past, not been marked, we can't always verify by inspection that the CY, SY or YY cable is actually rated as a power cable, rather than an auxiliary cable - but that could also be remedied by having appropriate marking requirements included within the constructional standard).
