Importance Of Salt Spray Testing In Metal Component Testing

2 Mins read

Manufacturing high-quality products is a difficult task. Plenty of researches are required to keep the product in the right manner. Manufacturers use high-quality testing instruments for testing their products whether they have any defects or not. The products are tested again and again to deliver high-quality products to the customers. 

Here in this blog, we will discuss about metal products. In the industries in which metal is a prime material for manufacturing products, it’s important to test the quality and durability of metals. The main thing that affects the quality of metals is corrosion. So, it is very important to test the corrosion resistance properties of metal products before selling them in the market.

If you do not test the corrosion resistance of metal products, then they might have a change in quality over the years. If the quality is damaged, it will affect the quality standards of the company. So, it’s important to test the corrosion resistance of metal products to determine how long these products would last and if the products need any changes.

Hence, for determining corrosion resistance, the most common method used is a salt spray test which is conducted by using a machine named a Salt spray chamber.

In a salt spray test chamber, a corrosive environment is created and the sample is placed in the chamber. After the set time, it will tell you the corrosion resistance properties of the sample product.

The procedure of Testing with a Salt Spray Chamber

A salt spray test is a standard method for determining the corrosion resistance properties of different products. In conducting a salt spray test, a sample product is placed in the chamber and a constant flow of salt-laden fog is subjected. The entire test is followed by this flow. After the set time, manufacturers take out the sample and test if there are any signs of corrosion or not, and then after research, they come to know the corrosion resistance properties of their products. 

Moreover, this method is used in the automotive and industrial sectors. Also, this test is conducted to evaluate the materials used in aircraft, marine, and military equipment.


  • This device allows you total control over stimulating salty fog with up to 5% NaCl.
