Salt spray testing is a standardized method used to evaluate the corrosion resistance of materials, particularly coatings and surfaces. These tests follow uniform rules and are designed for repetitive evaluation. The salt spray test standard defines the environmental conditions such as temperature, humidity, sodium chloride solution concentration, and pH value, while also setting technical requirements for the performance of the salt spray test chamber. Below are some common standards used in salt spray testing, which are provided for reference only.
GB/T 2423.17—1993: "Basic Environmental Test Procedures for Electrical and Electronic Products — Test Ka: Salt Spray Test Method"
GB/T 2423.18—2000: "Environmental Testing for Electrical and Electronic Products — Part 2: Test Kb: Salt Spray, Alternating (Sodium Chloride Solution)"
GB 5938—86: "Test Method for Corrosion Resistance of Metal Coatings and Chemical Treatment Layers of Light Power Products"
GB/T 1771-91: "Determination of Neutral Salt Spray Properties of Paints and Varnishes"
The results of a salt spray test can be evaluated using different methods. One common approach is the rating determination method, where the percentage of corroded area relative to the total surface area is classified into several grades. This method is ideal for flat samples and is often used to determine if a product meets specific corrosion resistance criteria. Another method is the weighing determination, which involves measuring the weight of the sample before and after the test to calculate the amount of material lost due to corrosion. This is especially useful for assessing the corrosion resistance of metals. Lastly, the corrosion occurrence method is a qualitative approach that simply checks whether corrosion has occurred on the tested item. This method is commonly used in general product specifications.
Understanding these standards and evaluation techniques is essential for manufacturers and engineers who need to ensure their products meet durability and quality requirements under corrosive conditions. Whether you're testing electronic components, metal coatings, or painted surfaces, selecting the right standard and evaluation method can make a significant difference in the reliability of your results.
