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 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.
What is the Salt Spray test and how many test methods are in SST?
The salt spray test is a laboratory test which is done to test the corrosion resistance properties of metals. 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.

Key Components and Steps For Salt Spray Chamber
Test Chamber:
A salt spray chamber, also known as a fog chamber, is the primary equipment used in the test. It is designed to create a consistent and reproducible corrosive environment.
The chamber is equipped with atomizing nozzles that generate a fine mist of saline solution.
Saline Solution:
The solution typically consists of 5% sodium chloride (NaCl) dissolved in distilled water, although different concentrations and additives can be used depending on specific standards and requirements.
The solution is maintained at a pH range of 6.5 to 7.2 to simulate natural sea spray.
Sample Preparation:
Samples to be tested are cleaned, dried, and placed in the chamber. They are usually positioned at an angle to ensure uniform exposure to the salt mist.
The samples can be metals, coated metals, or other materials.
Exposure:
The chamber is sealed, and the saline solution is atomized to create a fog that settles on the samples.
The temperature inside the salt spray chamber is maintained around 35°C (95°F) to promote consistent corrosion conditions.
The duration of the test varies depending on the requirements, ranging from a few hours to several weeks.
Assessment:
After the test period, samples are removed and analyzed for signs of corrosion, such as rust, pitting, blistering, or loss of adhesion in coatings.
Various assessment criteria, including visual inspection and mechanical tests, are used to evaluate the extent of corrosion.
Fundamental Principle for Salt Spray Testing
The fundamental idea behind this test is that materials exposed to salt mist will experience oxidation or corrosion on their metal surfaces. The type of metal, the atmosphere, and the presence of finishes or coatings that provide protection all affect how intense this process is. Faster laboratory testing findings are made possible by the accurate assessment of materials’ corrosion resistance provided by the Effective Lab salt spray test tester.
Typically, a salt spray test involves placing samples within a chamber and exposing them to a fine mist of NaCl salt continuously for predetermined amounts of time at controlled intervals. You may readmore about using a Cass Cum Salt Spray Chamber to perform a salt spray test with ease.
The fundamental principle behind the salt spray test is to simulate a corrosive environment to evaluate the corrosion resistance of materials and coatings.
Here’s a more detailed breakdown:
Simulating Harsh Conditions: The test exposes materials to a controlled corrosive environment, typically a saltwater mist, which accelerates the natural corrosion process that the materials would undergo in a real-world setting. This allows for a rapid assessment of their durability and performance.
Salt Solution: A saline solution, usually a 5% sodium chloride (NaCl) solution, is atomized into a fine mist and sprayed into a closed testing chamber. The salt solution is chosen because it closely mimics the harsh conditions that materials might face in marine or coastal environments, or from road salt in winter conditions.
Environmental Control: The temperature and humidity within the test chamber are carefully controlled to ensure consistent and repeatable results. Typical conditions are maintained at 35°C (95°F) with high humidity.
Time-Accelerated Testing: By subjecting materials to continuous exposure to the salt spray, the test significantly accelerates the corrosion process. What might take months or years to occur in natural conditions can be observed in hours or days within the test chamber.
Assessment and Evaluation: After exposure for a predetermined period, the materials are examined for signs of corrosion, such as rust, pitting, or deterioration of coatings. The extent and type of corrosion provide insight into the material’s or coating’s effectiveness at resisting corrosion.
Standards and Protocols

Do You Know What is a Salt Spray Chamber?
A cutting-edge lab testing instrument manufactured by Effective Lab India assesses the ability of metals to resist rust. As a result, the manufacturer can achieve optimal customer satisfaction by offering perfectly tested products and building a strong brand name. The salt spray chamber is a cutting-edge laboratory testing device which is the outcome of exceptional engineering, great hard work and a commitment to producing high-quality final goods by identifying uncertainties at the initial stage. Let’s take a look at the functioning of this instrument and understand how it helps manufacturers in various industries in assessing the materials’ resistance to corrosion.
Working of Salt Spray Chamber
The functionality of this lab testing instrument, which guarantees precision and consistency along with cutting-edge features, makes it useful in many industries. The apparatus can be divided into four main categories.
1. The interior compartment 2. Tank reservoir3. Saturator of air 4. Panel for electricity
The specimen must be placed inside the inner chamber by the operator before starting the salt spray test procedure. Three placing locations of samples are available in the inner chamber. These places depend on the operator’s needs and the sample’s size. To prevent external contact that could contaminate the sample and cause corrosive effects on the exterior, position the specimen correctly and close the inner chamber canopy when placing the specimen inside. The operator can easily profile the specimen using an HMI-based touchscreen attached to the electrical panel.
How Does It Work?
An entrance pipe allows demineralized water from the reservoir tank, filtered through a layer sponge filter, to mix with salt (NaCl) and generate a solution. This solution is then pumped to the inner chamber. By functioning at 45 degrees Celsius, the air saturator raises the temperature of the air and adds humidity to it. Via an entrance pipe, the humidified air enters the inner chamber. Using an atomizer and an igus coated with a fog dispenser, the system distributes the salt-water solution from the reservoir tank throughout the inner chamber along with the humidified air. This combination of salt water and humidified air produces a concentrated fog, evenly applying it across the specimen.
The fog dispenser evenly distributes fog throughout the specimen, while silicon bag heaters built into the inner chamber walls maintain temperature elevation for long-term testing. At this point, manufacturers can measure uncertainties (if any) and eliminate them at this early stage by simply evaluating the tested specimen’s responses to the artificial climate surrounding it. The HMI-based touchscreen on the salt spray test equipment displays the test results, making it simple and smooth to track outcomes and critically analyze previously acquired data. The operator needs to utilize the air purge once the salt spray test is over, as this helps to disperse the concentrated fog that is caused by high compressors inside the inner chamber, before opening the canopy. This must be done to protect the instruments housed outside from the inner chamber’s corrosion-friendly atmosphere. The salt spray test machine contains a few characteristics that cover the instrument’s flawless operation with complete ease and help the operator execute the test with no difficulty at all.
