CEROX Ferroxyl Test Kit
The ferroxyl test is used to determine whether stainless steel surface needs to be pickled or whether it has been pickled correctly. It tests for the presence of iron contamination on the surface. When the protective and impermeable passive layer on the stainless steel surface is not formed properly, iron contamination will be present. Iron presences deteriorates stainless steel properties such as reduced corrosion resistance. When iron particles are not removed, stainless steel surface faces a serious risk of corrosion. If the test proves the surface iron contamination, the surface needs to be pickled and/or passivated.
Reaction Time: 1-2 minute
Application: With a moist cloth, wipe the test surface and remove all dust. Prepare the testing solution by adding Solution A and Solution B in a 1:1 ratio. Shake the bottle until a homogeneous solution forms. Apply the testing solution onto the surface to be tested using a dropper. At the end of the reaction time if the surface has blue discoloration, the surface has iron contamination. This is an indication that the surface is not pickled correctly. Pickle and/or passivate the contaminated surface. If the surface has not discoloration, the surface has not iron contamination. This pickling has been done correctly. Once the test is completed, rinse the surface with drinking water.
Application Pre-Caution: If the surface has pickling chemicals residue, the test could result in blue color and indicate an iron contamination. Hence, wash the surface thoroughly after pickling process and wait for at least 24 hours before applying the test. When a surface treatment chemical (pickling, etc.) is applied on a stainless steel surface, wait for at least 24 hours before applying the test.
Caution: The prepared testing solution can be used for 2 hours. Use goggles, gloves, and appropriate protective clothing during application. In case of skin contact wash the contact area with plenty of water. Store in a cool place away from direct sunlight.
