4090 was never accepted by US DOD or ANSI/SAMMI, and was not implemented by the US.
Strongly advise keeping in mind the fact NATO is a treaty that has no enforcement element. NATO treaty signatories pursue their own interests without regard to NATO treaty obligations. NATO Standard Agreements are something of a bad joke.
