USING PROCEDURE OF FERROXYL TEST KIT FOR IRON FREE PASSIVATION
It consists of two solutions, TK-F1 & TK-F2,
Mix Solution TK-F1 & TK-F2 1:1. ( which contain nitric acid and potassium ferricyanide. The potassium ferricyanide can emit lethal fumes if it is exposed to concentrated acids, or heated to decomposition. The mixed solutions are combined before use as the mixture has an active shelf-life of approximately 24 hours. )
1st option ::: A filter paper is soaked with the mix solution and applied to the surface to be checked. After a reaction time of 30 - 60 seconds, ferrite residues, which are on the surface, will give a blue result if when iron is present.
2nd option ::: Alternatively, this mixture can be sprayed by atomizer spray over the area to be tested , and inhalation of this spray should be avoided.
Important note :
- The tested surface has to be cleaned immediately after with de-ionised water.
- Highly trained personnel should only be permitted to perform this test.
- Residues of pickling products will also show a blue colour.
