The Salt Spray Test chamber is suitable for several industries including aerospace, metals, automotive and others. By testing the products with the help of a environmental test chamber, producers can simply verify the durability of their products.

What is Salt Spray Corrosion?

Corrosion is the degradation of the materials of the environment. It occurs in the atmosphere where the components are corrosive and the conditions are humidity, oxygen, temperature fluctuations and contaminants. This is the most prevalent and devastating type of atmospheric corrosion. The testing chamber is mainly manufactured for evaluating the corrosion from the material or its coating. The chloride ions in SS corrode the surface of metal materials by penetrating the oxide layer and protective layer. 

Following are Some Features of the Salt Spray Fog Chamber.

  • The structure is waterproof to prevent SS overflow.
  • Equipped with salt solution and adopts the tower spraying system.
  • The working room temperature of the Corrosion Chamber ranges from RT +5C to 50C. And saturated barrel temperature is +40C-63C.
  • The test time of SS is 0-99,999m.
  • Spray methods are AASS, NSS, CASS.

This is the most reliable instrument for checking the corrosion of coatings. This instrument is designed to test the ability of products to withstand atmospheric conditions. The temperature of the test in the Corrosion test chamber is adjustable which is +40C and it is controlled by a controller system known as PID.

When it comes to the corrosion testing methods, there is only one common method which is using the Fog Test Chamber

It is a chamber used to simulate the effects of corrosion on test samples by spraying them with a salt solution. This aids in assessing the resilience and longevity of materials. It is a common technique used in different industries to check the durability of a product.

What is the Salt Fog Test Chamber Price in India?

The pricing of the Salt spray fog 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. In India, the general pricing of the Salt Spray Test Chamber starts from 1.78 Lakhs INR to 4.87 Lakhs INR.

Who are the best Salt Spray Testing Chamber Manufacturers in India?

Some industries manufacture Salt Spray Chamber in India. But Effective Lab India is the best and most reliable Environment Chambers manufacturer located in Faridabad, Haryana India.

What is Salt Spray Test?

The Salt Spray test is a laboratory test that is conducted to test the corrosion resistance properties of several metals and coatings. This test is conducted by using a machine which is termed a Salt Spray test chamber. Let us dive into the details of this testing chamber. All the necessary information regarding the salt spray test chamber will be covered in this blog. So, let’s start.

How many test methods are in SST?

In SST, a 5% solution of NaCl is made and salt fog is produced in the salt spray chamber. The sample to be tested is placed inside the test chamber and changes on the sample would be monitored.

Test methods

Three test methods are used for conducting a salt spray test.

  • Acetic Acid Salt Spray test
  • Material for testing: Chromium Plating, Cadmium Plating on Zinc and steel.
  • 5% Neutral Salt Spray Test
  • Material for testing: Platings and coatings on metallic parts.
  • CASS( Copper Accelerated Salt Spray Test).
  • Material for testing: Decorative Copper Nickel chrome plating, Zinc die castings, Anodized Aluminium.

History of SST

The first testing method was developed in 1910. It was not standardized for 30 years. It was done after 30 years on the release of ASTM B117 in 1939. The earliest standard varies significantly in which the level of salt is 20%. This concentration of salt was high and it causes problems in accurate test results. Later, it was discovered that reducing the salt concentration to 5% would accelerate the test result without any negative drawbacks. So, in 1954 the ASTM standard was revised with a concentration of 5% NaCl.

Parts required for Salt Spray Test

The following parts can be salt spray tested.

  • ED coating parts
  • Painted Parts
  • Phosphate Parts
  • Powder Coating Parts
  • Zinc Plating and Zinc Alloy Platings

Preparation of solution for SST

Preparing a solution for SST is carried out in a very easy method. All you have to do is just take fresh DM water add 5% NaCl in the water and mix it well. 

Most importantly, check the pH of the DM water before dissolving in the NaCl.

Parameters required for Salt Spray testing

For conducting a salt spray test, the following parameters are required.

  • pH: 6.5-7.2
  • Temperature of test chamber: 35+-1degree
  • Spray Pressure: 0.7-1.8kg/cm2
  • Temperature of saturated tank: 47+-1degree
  • Fog Collection: 0.85-2.0ml/h for 80cm2.

Reason for using salt spray test

Quality control: Product quality is vital for global manufacturers. Salt spray chamber allows the manufacturers to maintain their quality standards. It makes sure that the products meet the industrial standards.

Assurance: Numerous industries have specific requirements and specifications for corrosion resistance. The salt spray test chamber ensures the compliance of products with these standards. As a result, manufacturers expand into the global market.

Realistic simulation: In salt spray testing, corrosive conditions are made which may faced by material and coatings. This realistic simulation helps the manufacturers in assessing the performance of their products in the real world.

Weakness identification: Salt spray testing allows manufacturers to identify the weaknesses in the coatings of their products. If there are any weaknesses, the manufacturers can improve the quality of their products.

Cost savings: Salt spray testing may look expensive but it is cost-saving.
