There's a perhaps surprising number of things that are not done in a standardized way. Firefighting in general is still done in a very local fashion vis. best practices, equipment, etc... With the exception of the radio codes and the national / international standards for labeling shipping containers (necessary because if a firefighting team rolls up on an overturned tractor trailer engulfed in flames, they need to be able to tell quickly whether the trailer contained the sort of thing that pouring on water will douse or the sort of thing that pouring on water will cause spatter or (much worse), violent combustion / polymerization reactions.
One day is it clearly obvious that you should let people self-organise and let good ideas float up without regulation.
The next day it is clearly obvious that everyone should standardise.
I have also heard that these standards only apply if you want to describe your vegetables as meeting the standard. If you don't then I have heard that they don't apply.
I don't know if either of those are true or not, or if it's a meaningful excuse for anyone, though. You could argue the EU should have got involved and got everyone to agree to abolish the regulations, or you could think that a common way of describing vegetable standards is good.
