In order to verify that the metal parts on the charger are exposed to the atmosphere or other environment, corrosion may occur. The charger may be placed in the use environment for a sufficient period of time, such as a life cycle of the charger. This is time consuming and laborious. In practice it is rarely used.
This requires a convenient way to evaluate the corrosion resistance of the charger.
Salt spray test is an accelerated corrosion evaluation method for artificial atmosphere. It atomizes a certain concentration of salt water and then sprays it in a closed incubator to observe the change of the sample to be tested in the box for a period of time. Reflects the corrosion resistance of the sample being tested.
It is an accelerated test method, which is short-lived, does not require a few years, only takes a few days, or even hours.
Although the salt spray test is an effective test method, but due to many factors affecting corrosion, a single salt spray resistance cannot be used as a representative of other media, so the salt spray test results cannot be used as the test material in all environments. A direct guide to corrosion performance. At the same time, the performance of the material in the test cannot be used as a direct guide to corrosion resistance during use.
Nevertheless, the salt spray test method can still be used as a method for testing the test materials.
