I guess a lot of standards are this way to some extent but like, a voluntary certification produced by some random company for profit is barely a standard at all, when it comes to certification of life-safety-critical equipment. That's what I meant by "kinda aren't any requirements, it's all voluntary".

It's kinda silly that the guy who tries to go out to sea in a plastic bubble or whatever gets stopped by the coast guard but rich idiots they're like "go ahead sir right away sir"
