ISO 4628

ISO 4628 is a standard that defines the methods for assessing the degradation of paints and coatings after exposure to corrosive environments, including salt spray tests. This standard specifies how to evaluate various forms of coating damage such as blistering, rusting, cracking, flaking, and chalking, which can occur when materials are exposed to harsh conditions like moisture, salts, or chemicals.

ISO 4628 provides visual reference scales and numerical ratings to quantify the level of degradation, ensuring consistency and accuracy in the evaluation process. This helps manufacturers determine the durability and protective quality of their coatings over time, making it essential for industries that rely on high-performance materials, such as automotive, construction, and marine sectors.

At Pacorr Testing Instruments Pvt Ltd, our Salt Spray Chambers provide the controlled testing environment required to conduct evaluations as per ISO 4628. This allows manufacturers to assess coating performance and make necessary improvements to ensure their products meet international corrosion resistance standards.
