The AIM isn't a rule book. It's really a book of good advice, of which quite a lot could be considered relevant to non US ops, so it would apply (unless you don't like taking advice
)
Of course if you are flying on an FAA certificate, you fail to follow the advice and have an accident, the FAA could come after you for being 'careless and reckless'. But for your purposes the advice about altimeters should be considered applicable. IMO. Altimeters work the same way all over the world, and the one you are using was probably made and certified in the USA anyway.
But as I asked earlier, if anybody has a reference to 50ft then that would be interesting too. Nobody has as yet delivered. Until they do, and it's in a CAA document, then I suggest that the AIM reference I provided you is the best ammunition you have got.
