Hungarian term (edited): Minős�t�ses �tv�teli elj�r�s, �tv�teli szint

It would have been better if you put these two phrases as separate questions.
Anyway, I can tell you the second one right now, I may be able to find the first one, too.
"átvételi szint" is AQL (Acceptable Quality Level), and it means:
"This is usually defined as the worst case quality level, in percentage or ratio, that is still considered acceptable."

As for the other phrase, "minősítéses átvételi eljárás", here is some explanation in Hungarian:
"A vizsgálat eljárása minősítéses, amely azt jelenti, hogy
egy vizsgált termék bármely nem megfelelősége esetén azt
a darabot hibásnak tekintik. "
This is from here:

This procedure means that if the product under inspection does not conform in any way, the item is considered defective.

I found the English version, look:
\"Cím: Termékek folyamatos statisztikai átvételi minőségellenőrzése minősítéses eljárással
Angol Cím: Continuous statistical acceptance quality control by attributes\"

\"Attributes acceptance procedures\" is used here:
See this one, too:

So, the translation of \"Minősítéses átvételi eljárás\" can be based on these, for example:
\"acceptance procedure by attributes\", or \"Attributes acceptance procedure\"
