> Does this also mean only using "standard" parts? Or does the manufacturer have to over-produce the parts for, lets say 7 years

Why not? I don't understand how it's legal for manufacturers to produce absolute trash that can't be replaced and will just end up in a landfill. I think 7 years is far from enough, but because computers evolve quickly maybe 15 years is ok. For the rest of electro-mechanical goods, 50 years should be the baseline.

If a car or fridge from 50 years ago is still working with proper maintenance, that should be the minimum to be expected from products released today.
