The corrosion resistance testing standards for automotive parts mainly have the following requirements for the performance of parts: **I. Material performance requirements** 1. Corrosion resistance: The material of parts should have good corrosion resistance and be able to resist the erosion of corrosive media under different environmental conditions. For example, in environments such as salt…
When choosing appropriate automotive parts according to corrosion resistance testing standards for automotive parts, the following aspects can be considered: **I. Clarify the usage environment** 1. Consider geographical regions: Climate conditions vary greatly in different regions. For example, in coastal areas, the air humidity is high and the salinity is large. In acid rain areas,…
The testing standards for corrosion resistance of automotive parts mainly include the following: **I. Salt spray test standards** 1. Neutral salt spray test (NSS): Such as international standard ISO 9227. Use sodium chloride brine with a concentration of 50g/L, and the pH value is between 6.5 – 7.5. Place the sample of automotive parts in…
Internationally, there are a series of standards and test methods for the corrosion resistance of automotive sheet metal parts. The common relevant standards are as follows: 1. **Salt spray test standards**: – **Neutral salt spray test (NSS)**: For example, international standard ISO 9227 is a widely used salt spray test method. Use sodium chloride brine…
