ASTM A380 Ferroxyl Test Kit – Iron Contamination Analysis Reagent
Formulated specifically to detect free iron (Fe²⁺ / Fe³⁺) contamination on stainless steel surfaces with high precision, the ASTM A380 Ferroxyl Test Kit is an indispensable part of industrial quality control processes. Manufactured by Gündüz Kimya with high purity laboratory-grade chemicals, this specialized testing solution is fully compliant with Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts. Available in 50 ml and 100 ml options, this product provides instant and definitive results through a Prussian blue reaction, especially on weld seams, bending points, and Heat-Affected Zones (HAZ).
Kit Contents and Chemical Mechanism
The ferroxyl test is based on the principle that free iron particles on the surface react with specific chemicals to become visible. The contents of your analysis set are as follows:
-
Solutions: 1 x 50 ml Solution I and 1 x 50 ml Solution II.
-
Application Equipment: 20 special cotton application swabs and 1 pair of protective nitrile gloves.
-
Documentation: 1 corporate user manual.
If there is free iron contamination on the surface, the prepared chemical mixture instantly forms a characteristic dark blue color (Prussian Blue), clearly indicating that the material requires immediate acid passivation.
Standard Test Method and Application Steps
To ensure the test provides accurate and reliable results, perform the following steps in order using your ASTM A380 Ferroxyl Test Kit:
-
Surface Preparation: Ensure that the stainless steel surface to be tested is completely free of oil, dust, general contamination, and is completely dry.
-
Combining the Solutions: Take one of the cotton application swabs included in the package. Apply 1 drop of Solution I to the cotton tip, followed immediately by 1 drop of Solution II on the exact same spot. Never mix the two liquids inside the bottles; only combine them on the swab at the time of the test to ensure a fresh reaction.
-
Application to the Surface: Gently press and rub the prepared wet cotton tip onto the area you want to test and wait for 10-15 seconds.
-
Cleaning: After the test is completed, the stainless steel surface where the reagent was applied must be wiped with a wet cloth or water to prevent staining. To prevent cross-contamination, the caps of Solution I and II must never be swapped.
Evaluating the Test Results
Reaction results must be evaluated within a maximum of 30 seconds for accurate ASTM A380 Ferroxyl Test Kit readings:
-
Blue Color (Prussian Blue) Formation: If a dark blue color/stain forms on the cotton or the surface, it means there is free iron contamination on the surface that can cause corrosion.
-
No Color Change: If no blue staining is observed, the surface is clean. The corrosion resistance meets the standards.
-
False Positive Warning: If the solution is left on the surface for more than 1 minute, it may turn blue spontaneously due to atmospheric oxygen; therefore, the evaluation must be made within the first 15-30 seconds.
Safety, Storage, and Disposal Guidelines
Always wear the protective gloves and safety glasses included before application. Avoid contact of the ASTM A380 Ferroxyl Test Kit reagents with eyes and skin; in case of contact, wash with plenty of water. Store the products upright between +15°C and +25°C (at room temperature), away from direct sunlight. Used cotton swabs and gloves must be disposed of as hazardous/industrial waste in accordance with local environmental legislation.
