Application Summary AI generated
This standard specifies the blue dot method for testing the quality of passive films on austenitic stainless steel surfaces after chemical cleaning. It is applied in industrial settings to verify the integrity and corrosion resistance of the passive layer on equipment such as tanks, pipes, and reactors in chemical, pharmaceutical, and food processing industries. The test is conducted during maintenance or after cleaning procedures to ensure the stainless steel surface is properly passivated and free from contamination.
