ISO 9227 European standard for salt spray testing
ISO 9227 is a European standard that deals with salt spray testing. This is a method to test whether the quality of a metallic material can be maintained without or with corrosion protection. There are various factors that can influence the progression of corrosion. They have very different effects on the formation of protective layers.
By choosing salt spray fog testing as a corrosion test, it is possible to determine very quickly whether weak spots, pores or damage are present in organic coatings and inorganic coatings.
Samples are taken for quality control. These samples are provided with the same coating or with the same coating. This is an important prerequisite, because salt spray testing is only suitable if the individual coatings are of the same type.
