You have to be a bit careful comparing the requirements around old incandescent lamps to more modern equipment.
The glass envelope filament lamp requirements have a lot of history attached. You couldn't, for example, pass an Edison or bayonet mains lampholder using typical modern requirements because with the lamp removed, (an action not requiring a tool), you can poke your finger into the then accessible live terminals. Similarly, given that the glass envelope is the means by which access to the live filament is prevented, it ought, using more recent thinking, to be able to survive an impact hammer test, but of course it couldn't. It's just that there are so many installed that we are stuck with them.
