For fly ash, you can do a sieve test on each lot either dry or wet depending on your preference or ease. the 90 % ash should pass through 45 micron sieve.
Apart from this you can only do a review of MTC supplied by supplier.
If you find something wrong or feel any issue, you can always get it tested from third-party laboratory for its chemical properties.

Its up to you to define a acceptance criteria on fineness, as this is going to make difference in properties of my concrete.
If you seen 34% then you must have seen definitions and kind of ashes comes from plant like pond, mond etc. highest fineness is found in the flyash.
You can have the acceptance to 34% (as per IS) for retained particle or you can define if you are getting finest quality in your area.
You can do all Physical and Chemical tests as prescribed in IS code on every lot or as per the frequency you or your management specifies.
there is nothing much which can be done with flyash at current condition, also flyash is used when we have RMC plants, it indicates the consumption of flyash does happens in a day or two. so getting something failed result from third party and getting OK results in concrete you produce does not make any sense and situation even goes worse.
Finally it up to us on what criteria to be set for acceptance base on practical conditions and design assumptions.
