Salt spray testing is a commonly used reliability testing method for electrical and electronic products, used to evaluate the tolerance and reliability of products in salt spray environments. Salt spray testing is usually used to verify the performance and stability of products in high temperature, high humidity, and salt spray environments. So, which products require salt spray testing? To help everyone gain a deeper understanding, the following content is organized by Chuangxin Testing Network and provided for your reference.

When salt spray testing is required for electrical and electronic products, it is first necessary to select suitable testing standards and conditions based on the actual situation of the product. For example, for electronic components and components, the ISO 7812 standard is usually used for testing, for communication equipment, the EN 55012 standard is usually used for testing, and for medical equipment, the ISO 15843 standard is usually used for testing.

After selecting the testing standards and conditions, it is necessary to prepare and process the test samples. The preparation of test samples usually includes pre-treatment to enable them to adapt to the testing environment. For example, for electronic components and components, cleaning and treatment are required to ensure that the sample surface is clean and dust-free. For communication and medical equipment, it is necessary to shield the samples to avoid external interference during the testing process.

When conducting salt spray testing, it is necessary to place the test sample in a specified testing environment, usually at a temperature of 30 ° C to 35 ° C and a humidity of 60%. The testing time ranges from 48 hours to 72 hours, and may vary depending on the testing standards and conditions. During the testing process, it is necessary to regularly inspect the samples to ensure that their performance and stability are not affected by the salt spray environment.

Some products that require salt spray testing:

Cars and motor vehicles: In the production process of cars and motor vehicles, including the body, engine, chassis, and appearance, salt spray testing is required to verify their corrosion resistance and durability in marine environments. At the same time, salt spray testing can also test the adhesion and color stability of the vehicle's paint surface.

Aerospace and Ship: In the manufacturing process of aerospace and ship manufacturing, salt spray testing is widely used to test the corrosion resistance of metal and non-metallic materials, ensuring their long-lasting reliability in the ocean or other harsh environments.

Hardware tools and metal products: Hardware tools and metal products are often exposed to Corrosive substance such as sea water and salt spray, so salt spray test is required to verify their corrosion resistance. Salt spray testing can test the performance of hardware tools and metal products in corrosive environments, including their color stability and surface coating durability.

Electronic products: Circuit boards, electronic components, and batteries in electronic products require salt spray testing to test their durability in humid and hydrochloric acid containing environments. Salt spray testing can test whether the electrical conductivity of electronic products meets standard requirements and whether their durability is long enough.

Plastic and rubber products: Plastic and rubber products are prone to corrosion in environments containing hydrochloric acid, so salt spray testing is required to verify their corrosion resistance. Salt spray testing can test the quality and durability of plastic and rubber products in environments containing hydrochloric acid, including their water absorption performance and appearance stability.

Select appropriate testing standards and conditions based on the actual situation of the product, and conduct sufficient preparation and processing to ensure the accuracy and reliability of the test results. It should be noted that different products may require different standards and conditions for salt spray testing, and suitable testing standards and conditions should be selected based on the actual situation of the product. At the same time, before conducting salt spray testing, it is necessary to fully prepare and process the test samples to ensure the accuracy and reliability of the test results.
