With the advancements being made in technology, it has become easier to test out effects certain environments or conditions will have on products. This, then leads to better product development. These testing include many different kinds, ranging from impact of environment to that of corrosion. This article will explore what a salt spray chamber is, what kind of impact it has on products and how exactly is salt spray testing conducted.

Salt Spray Chamber

A salt spray chamber is basically used to test out the protective layer of electric and electronic parts, metal based materials as well as industrial goods. Through a corrosive saline environment laboratory simulation, it helps to figure out the corrosion resistance of coatings and materials of different products. In order to better forecast how effectively the coating protects the metal during salt spray testing, an accelerated corrosive attack is developed. Salt spray chambers are usually used to see the corrosive properties of things such as organic or paint coatings, non-electrolytic coatings, zinc and zinc alloy plating and electroplating among other things. 

Salt Spray Testing 

Salt spray testing uses a corrosive attack on coated samples to determine whether or not the coating is suitable for use as a protective finish. After a predetermined period of time, the appearance of corrosive products, be it rust or some other oxides, is assessed to see how well the product fares against corrosion.  Because it is quick, repeatable, and very inexpensive, salt spray testing is generally the standardized corrosion test method.

How to conduct Salt Spray Testing

To conduct a salt spray test in a salt spray chamber like the one supplied by LISUN, you initially press the red power switch after plugging in the chamber. At this point the lights for low water level A, low salt water level B and low water level C turn on. Afterwards, distilled water is poured in the test chamber directly until the water level indicator A lights turn off. Next, according to test requirements, solution is prepared, which is then poured into the box marked ‘Reagent Inlet’ until the low salt water B indicator light turns off. Then distilled water is added to the pressure tank manual water filling point till the level C indicator goes out, after which the valve is closed. 

Then, the glass rod and V-shaped sample rack are placed in the test chamber, followed by the required test sample. Afterwards, lid of salt spray test chamber is closed and distilled water, exceeding the gap between lid and body, is poured into the lid groove to water seal it. Air compressor is powered on and connected to salt spray test chambers air inlet then the air compressor’s red button is pulled up and the valve switch is opened. Next, the instrument is set to appropriate time and temperature standards. This includes setting up everything ranging from pressure tank temperature, laboratory temperature, spray time, interval time amongst other things. Then the test is started by pressing the spray and timer switch.

 Now the test will take place according to the set conditions. After the salt spray test is complete, the salt mist in the chamber is discharged by the defogging switch. Completing this procedure allows for the removal of the test sample and consequently study the impact the salt water had on it. The test sample is rinsed with running cold water or cleaned with bleach to remove salt residues and deposits. Then it is dried immediately after which it is checked for corrosion and other defects. 


This entire process gives you an idea of how a certain product will fare against corrosion and in turn helps make appropriate amendments to the product to increase its durability. The salt water testing, thus, proves to be a very useful and easy way to test out products.
