Cable types for fixed wiring are still something where harmonisation hasn't really caught on. Even most EU countries still largely use national types, although some are fairly similar. Even Austria and Germany, countries that share a common electrical history during WWII, cables aren't 100% interchangeable. While they look essentially the same, the Austrian versions have thinner isolation and especially outer sheaths.
I suppose harmonising cord types all over the world (i.e. adopting exiting harmonised types in countries that don't use them) would mainly benefit manufacturers and international wholesalers.
