History of Salt Spray Test and its Methods

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 performed using a machine called 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.

Material required for Salt Spray Test

The following material 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 the SST chamber is carried out very easily. All you have to do is just take fresh DM water, add 5% NaCl, and mix it well. Most importantly, check the pH of the DM water before dissolving in the NaCl.

Parameters required for Salt Spray testing

Introduction to Salt Spray Chamber: Working Principles and Key Features

Effective Lab Salt spray chambers are specialised testing apparatuses intended to replicate and expedite the corrosive impacts of environments high in salt on a range of materials and goods. These tests are frequently utilized to assess the durability and corrosion resistance of an item in extreme environments, including coastal or marine settings. Be it for metals, construction materials, or electronic components, this chamber is vital in ensuring products can endure the test of time and severe conditions. Let’s dive into what a salt spray chamber is, how it works, and its standout features.

What is a Salt Spray Chamber?

A salt spray chamber, alternatively referred to as a salt fog chamber, replicates and hastens the corrosion process on materials and coatings within a controlled environment. This equipment is essential in laboratories where materials undergo rigorous testing to determine their corrosion resistance. It is particularly important in industries that prioritize longevity and durability.

The Importance of Corrosion TestingCorrosion can be a silent destroyer, leading to catastrophic failures in materials and structures if not properly managed. By using salt spray chambers, manufacturers and researchers can predict how materials will behave in real-world conditions, ultimately saving time, money, and even lives. Corrosion testing aids in detecting potential weaknesses in materials. This process enables improvements before products reach the market.

How Does a Salt Spray Chamber Work?

The primary function of a salt spray chamber is to create a consistent and controlled corrosive environment. The working principle involves several key components and processes:

1. Saline Solution Preparation: The test begins with the preparation of a saline solution, typically a mixture of sodium chloride (NaCl) and distilled water. The concentration of the solution is usually around 5%, but it can vary depending on specific testing standards and requirements.

2. Atomization of the Solution: The saline solution is then atomized into a fine mist or fog using a nozzle system. This atomization process is crucial as it ensures uniform distribution of the corrosive particles within the chamber. The system directs the mist into the chamber where the test specimens are placed.

3. Test Specimen Placement: Test specimens, such as metal panels, coated surfaces, or assembled components, are strategically placed inside the chamber. The testing protocol determines the exposure period of these specimens to the saline mist, which can range from a few hours to several weeks.

4. Controlled Environment: The chamber maintains a controlled environment with a constant temperature, typically around 35°C (95°F). The system regulates the humidity level to ensure consistent test conditions. Sensors and controllers in the chamber monitor and maintain these parameters throughout the testing period.

5. Corrosion Monitoring: During the test, the specimens are periodically inspected for signs of corrosion, such as rust, pitting, or coating degradation. We assess the degree of corrosion based on predefined criteria, which can include visual inspection, weight loss measurements, or other analytical methods.

Key Features of a Salt Spray Chamber

Enclosed Chamber: The enclosed chamber is the primary structure of the salt spray test chamber where the test specimens are placed. It contains a corrosive environment, prevents any salt mist from escaping, and ensures a consistent testing atmosphere.

Atomization System: The atomization system is responsible for creating the fine mist of salt solution within the chamber. It includes a spray nozzle that disperses the salt solution into tiny droplets, mimicking natural environmental conditions that cause corrosion.

Temperature Control: Temperature control in a salt spray chamber maintains the internal environment at a specified temperature. This is crucial because temperature fluctuations can affect the rate of corrosion. The system uses heaters and sensors to regulate and monitor the temperature, ensuring it stays within the required range for the duration of the test.

Humidity Control: Humidity control regulates the moisture levels inside the chamber. Maintaining proper humidity is essential for creating realistic corrosion conditions.

pH Control: pH control ensures that the salt solution maintains the correct acidity or alkalinity levels. This is important because the pH of the solution can significantly influence the corrosion process. The system monitors and adjusts the pH of the solution to match specific testing standards, ensuring consistency and accuracy in the results.

Interlock Safety: The critical safety interlock feature protects users and equipment. This feature helps to avoid accidental exposure to the corrosive environment and ensures the safe operation of the chamber.

HMI Display: The Human-Machine Interface (HMI) display is a user-friendly interface that allows operators to control and monitor the chamber’s functions. It provides real-time data on temperature, humidity, and other parameters, and allows users to set test conditions, start or stop tests, and view historical data.
