Factors Affecting Salt Spray Test -PH Value
Apr 02, 2024| Factors affecting salt spray test -PH value
The lower the pH value, the higher the concentration of hydrogen ions in the solution, the stronger the acidity and the stronger the corrosion. Neutral salt spray test (NSS) pH value is 6.5~7.2. Due to the influence of environmental factors, the pH value of salt solutions will change. Therefore, the pH range of salt solution is specified in the salt spray test standards at home and abroad, and the method of stabilizing the pH value of salt solution during the test is proposed to improve the reproducibility of the salt spray test results.
