ASM standards

Are there any standards for ASMs such as they must consistently produce X% of randomness? If so, how is this verified and how often do State Gambling regulators verify after they are in use? If not, why not? It seems to me that they do a very poor job of randomizing cards, at least at the 8 deck blackjack game that I have available. I repeatedly see cards of the same rank come out in the same deal all night. Please don’t tell me that I have recency bias or confirmation bias, I don’t, it is real over many sessions.

I think GLI/BMM verifies them
