Corrosion is a significant problem faced by various industries and manufacturers globally. This is particularly relevant for products exposed to coastal environments, marine conditions, or other environments with high levels of salt or humidity. It is the most basic form of testing to determine the response of a sample under a highly corrosive environment. Most importantly, the instrument helps ensure the product meets the required standard specifications per the regulatory organisations and customer expectations. Salt spray test is also used in material selection, enhancing product durability and overall performance.
What is Salt Spray Test?
The salt spray test is an easy method to determine the corrosion resistance properties of a product, coating or paint layer. It is a cost-effective solution that allows testers to conduct the corrosion test in a controlled environment. The test is performed within enclosed chambers made of high-quality material like fibre-reinforced plastic. It is also used for relative performance comparison and coating selection.
The instrument enables accelerated testing wherein the solution maintains a highly corrosive environment that stimulates the corrosive process. Salt spray test allows testers to understand long-term corrosive effects on the sample comprehensively. The evaluation criteria of the test process can yield varying levels of corrosion. Conducting multiple tests on the sample ensures reliable test results.
Top 3 Applications Of Salt Spray Test
- It is used in the grade crucial parts in the automotive industry. The test assesses the quality of various parts such as fasteners, coatings, panels, chassis parts, etc.
- It helps ensure the safety of operational parts used in machinery exposed to harsh environments.
- It is used to check and gauge the reliability of electronic components like circuit boards, connectors, wires, etc.
How To Conduct Salt Spray Test
Step 1: Set up the salt spray test chamber based on the manufacturer's instructions. Ensure the insides of the chamber are thoroughly cleaned to remove any salt residue or contaminants.
Step 2: Place the sample within the chamber. Use appropriate holders to ensure uniform exposure. Set the parameters based on requirements and start the test.
Step 3: Monitor the changes observed on the sample's surface throughout the testing period. Record test observations such as rust formation, coating degradation or physical cavities observed on the sample.
The testers can compare the test results with globally accepted standards to assess the durability of the sample in real-life scenarios. It helps determine the performance of sample material, paint or castings. Every material or coating may react differently to the test or exhibit varying corrosion characteristics. Therefore it is essential to compare results with the general industry standards.
The temperature within the enclosed chamber can go up to 400 degrees. Hence it is essential to choose quality instruments designed to deliver long-lasting performance. It helps save expenditures in the long run and reduces the requirement of rigorous maintenance. The salt spray chamber by Pacorr is empowered with a humidity indicator, PID temperature control, a standalone sensor and a microprocessor-based digital control system for easy monitoring of the test procedure.
