Salt spray test is to specify the conditions of salt spray test, such as temperature, humidity, concentration of sodium chloride solution and pH value, and also put forward technical requirements for the performance of salt spray test chamber. The purpose of salt spray test is to assess the salt spray corrosion resistance quality of products or metal materials. The judgment of salt spray test results is just the judgment of product quality. Whether its judgment results are correct and reasonable is the key to correctly measure the salt spray corrosion resistance quality of products or metals.

Salt spray test cycle

The test time shall be determined according to the requirements of the tested covering layer or product standard; If there is no standard, it can be decided by relevant parties through consultation. The recommended test time is: 2, 6, 16, 24, 48, 96240480720h. Within the specified test cycle, spray shall not be interrupted. Only when the sample needs to be observed briefly can the salt spray box be opened. If the end point of the test depends on the time when corrosion begins, the test needs to be checked frequently. Therefore, these samples cannot be tested together with samples with a predetermined test cycle. The test of the predetermined cycle can be checked according to the above cycle. However, the test surface shall not be damaged during the inspection. The time for unpacking and inspecting samples shall be as short as possible.

Handling process of reliability salt spray test

1. Business consultation: the applicant provides product information, pictures and test requirements to a third-party testing institution;

2. Project quotation: according to the information provided by the applicant, the engineer will make an evaluation and make an oral quotation to the applicant;

3. Provide information: after the applicant accepts the oral quotation, the test samples shall be submitted to the third-party testing institution;

4. Payment: Send a written quotation to the applicant after receiving the sample, and the applicant will arrange payment according to the written quotation;

5. Sample test: conduct product test according to applicable standards;

6. Issue report: the laboratory will issue the third-party CNAs test report and close the case after the test is completed.
