RF 800 Flux ( cookson brand) - Flux acid calculation and restoration of acid value from 17 to 19

Hi,

I need the RF 800 Flux Acid titration procedure and also require EPT of the same to add thinner ( RF 800 additive),

i.e we are using the flux rf 800 for our wave soldering process having foam fluxer , after 2 hours we are taking sample from the flux tank and doing the acid number test ,the result will come around 19 to 24 in random, but we need to know how much quantity of thinner to be added to the flux to restore the acid number from 17 to 19.

Can anyone help on this topic. Best Regards, R.Ramesh.
