Guide to Salt Spray Testing Procedures, Benefits and Applications

A salt spray test chamber is used to test different types of materials under different atmospheric conditions for the materials of the products. In this method salt fog testing works on the materials to test the durability of your products against corrosion using this salt spray corrosion test chamber materials can be easily detected. The corrosion resistant properties of the material can be easily detected.

Effective Lab India is known as one of the leading lab equipment manufacturer suppliers in India that provides all types of labs testing machine manufacturer, the primary objective of this organization is to provide various types of labs testing machines including salt spray chamber, box compression tester, ozone test chamber and many other types of lab equipment supplier testing machine as per your client requirements.

Our material testing equipment manufacturer equipment’s are highly valued and fully satisfy the needs of the customers. If you are looking for material testing products at reasonable rates then this company has only the options for you which will provide you good in-house making manufacturing products under the presence of highly technical engineers.

We are the best manufacturer, supplier and exporter of Salt Spray Chamber Machine across the country. If I talk about salt spray chamber then this machine is very useful for various types of testing material corrosion, in today’s time every company wants to keep their products safe for a long time, because of this they need to do continuous testing by using this machine, this machine helps the customers to find out the good material.

Salt spray test chamber products are also known as salt fog test chambers, they are used to assess the resistance to corrosion of metal parts, surface coatings, zinc-plated nuts and bolts and paints, useful for many industries such as automotive, aerospace, construction, marine and many others to predict how well a material or coating will withstand a corrosive environment. Salt spray chambers or material testing equipment are both the same and referred to by the same name, but material testing includes different types of material equipment in relation to testing that is used to test the corrosion resistance of materials and surface coatings.

How to Conduct a Salt Spray Test and Salt Spray Test Procedure

Some common International Standard Test Methods:

• ASTM B117 – Most widely used standard test methods for NSS (Neutral Salt Spray)
• ISO 9227 – International Salt Spray Test Standard
• ASTM G85 – Modified tests (e.g., acidified salt spray, cyclic)

How Salt Spray Testing Works

1. Test Chamber Setup

A salt spray chamber is used – essentially a sealed box with temperature and humidity controls.

2. Preparation of Test Samples

• The test samples (e.g., metal panels, coated products) are cleaned and placed in the chamber.
• They are placed at an angle of 15° to 30° from vertical to ensure uniform exposure.

3. Preparation of Salt Solution

• A 5% sodium chloride (NaCl) solution is prepared with distilled or deionized water.
• The solution is pH-adjusted (typically 6.5-7.2 for neutral salt spray, or NSS).

4. Spray Mechanism

• The solution is atomized using compressed air to create a fine mist (salt fog).
• This mist is continuously sprayed into the chamber to coat the test samples.

5. Controlled Conditions

• The chamber is kept at 35°C (95°F).
• Exposure time varies depending on the standard or expected performance (e.g., 24, 96, 240, or 1,000+ hours).

6. Evaluation of Results

After exposure, samples are inspected for signs of corrosion:

• Rust, blistering, peeling, pitting
• Cracking of the coating
• Time to first corrosion occurrence

Conclusion:

• Purpose: To evaluate the corrosion resistance of materials/coatings such as metals (steel, aluminium, zinc, etc.), paints and coatings, plated surfaces (e.g., zinc-plated, chrome-plated), anodized surfaces
• Environment: Simulated salt fog/mist chamber
• Industries: Automotive, marine, aerospace, construction, electronics
• Value:  Provides fast, repeatable, and standardized corrosion testing
