Neutral salt spray test solution ratio
Dongguan Zhongzhi Times Testing Equipment Co., Ltd. Neutral salt spray test solution is generally prepared by dissolving sodium chloride (NaCl) in distilled water. The typical ratio is approximately 5% by mass.
The specific preparation method is as follows:
- Prepare the reagents: analytical grade sodium chloride and distilled water.
- Weigh a certain amount of sodium chloride, generally adding 50 grams of sodium chloride per liter of distilled water to obtain a solution with a mass fraction of approximately 5%.
- Slowly add the sodium chloride to the distilled water, stirring continuously to fully dissolve it.
- Ensure that the pH of the solution is between 6.5 and 7.2. If it is outside this range, adjust it with dilute hydrochloric acid or sodium hydroxide solution.
It is important to note that when conducting a neutral salt spray test, test conditions such as temperature and spray volume must be strictly controlled to ensure the accuracy of the test results.
