I don't have a direct answer, and as a builder, composition of foam is something I haven't taken an interest in until now, but fef foam isn't even mentioned in state or federal standards, and I'm not seeing many compliance as/nzs numbers on any of the advertising links you have put up.
I am happy to be corrected, but unless it jumps through official hoops it isn't going to appear too soon. As I said previously though, the arff changed to another sort of friendly/er class b foam some time back.
As to the why's all I know is that bad foam is poisonous, acidic, eats steel lines, smells vomitous, has nothing going for it apart from killing avgas/a1 fires, so there must be a strong argument to have kept it this long.
