Salt Spray Test Chamber

Regardless of whether you are a quality control laboratory checking for coating durability, an automobile company testing the performance of its components, or an electroplating company checking for surface quality, having the right salt spray test chamber is essential to your corrosion testing process.

Our salt spray chambers are built using microprocessor-controlled PID temperature controllers. All units are pre-calibrated and ready for ASTM B117/ISO 9227 testing.

Having supplied over 500 chambers in India's automobile, aerospace, and manufacturing industries, we know what your production line requires from corrosion testing chambers. This is not only a chamber but a quality assurance tool too.

What Is a Salt Spray Test Chamber?

A Salt Spray Test Chamber – also known as a salt fog chamber, salt fog chamber, or corrosion test chamber – is a lab-based environment designed to assess the corrosion resistance of metals, coatings, paints, and surface treatments. In a salt spray test chamber, a sodium chloride (NaCl) solution is atomized to create an accelerated corrosive environment, allowing years of environmental exposure to be simulated in just hours.

Salt spray testing is one of the oldest and most common types of corrosion testing available. Standardized according to ASTM B117 (which is regarded internationally as the benchmark test), salt spray testing offers a repeatable way of accelerating the corrosion process so that different coatings, plating finishes, and base materials can be compared.

From automotive and aerospace to consumer electronics and marine hardware industries, salt spray testing is used extensively to ensure that products meet required quality standards.

Working Principle (Step-by-Step)

Step 1 – Salt Solution Preparation
A solution of sodium chloride (NaCl) at 5% is prepared with demineralised water. The pH value is set between 6.5 and 7.2 by using reagent-grade chemicals. In the case of CASS testing, copper chloride and acetic acid are added.

Step 2 – Atomisation with Compressed Air
Compressed air (0.7 to 1.7 kg/cm²) passes through the spray tower nozzle, where it draws the salt solution and forms a uniform mist of 1-2 micron size.

Step 3 – Temperature Controlled Salt Fog Test Chamber
The test chamber is maintained at 35°C±2°C for NSS or 50°C for CASS. PID controllers maintain the stable environment during the entire test cycle.

Step 4 – Specimen Exposure
Specimens are hung at an angle of 15°-30° from vertical using non-conducting racks and exposed to salt fog continuously or cyclically for certain time period which could be 24, 48, 96, 240, or 500 hours.

Step 5 – Data Collection & Analysis
Test specimens are washed with clean water after testing and checked for blisters, rusting, delamination, or corrosion creep. Digital controllers record temperature, humidity, and run time automatically.

How does a salt spray chamber work?

Using the Corrosion Test Chamber is very simple, so even beginners can easily perform complex tests. Just follow these steps for the best results:

• Preparation: Begin by preparing the test samples according to the specific requirements of your industry standards. Ensure they are clean and free from any contaminants.
• Loading Samples: PCarefully place the samples inside the chamber, ensuring they do not touch each other or the chamber walls to avoid cross-contamination.
• Setting Parameters:Program the chamber with the required parameters such as temperature, humidity, and duration of the test. These parameters are crucial and should be set according to the standards you are adhering to.
  
• Starting the Test:Initiate the test cycle. The chamber will spray a fine mist of salt solution, simulating a corrosive environment.
  
• Monitoring:Regularly monitor the progress through the observation window or digital display. Ensure the chamber maintains consistent conditions throughout the test.
  
• Post-Test Analysis: Once the test is complete, remove the samples and analyze them for signs of corrosion. 

What is the Salt Spray Chamber Price in India?

The pricing of the salt spray chamber varies differently. There are several manufacturers which offer several prices for this instrument. This price ranges from country to country. In every country, the price should be different. The typical price of Salt Spray Test Chamber in India ranges from around ₹ 70,000 Thousands to ₹ 8,00000 Lakh.
