Are You Using the Salt Spray Test Chamber Correctly?

As a testing device that simulates atmospheric corrosion environments, the salt spray test chamber, like other equipment, requires operators to follow specific procedures to ensure smooth and accurate testing, personnel safety, equipment protection, and extended service life.

The salt spray test chamber uses water for sealing. Before testing, an appropriate amount of purified or distilled water must be added to the water tank on top of the chamber. The heating water tank and air saturator should also be filled in time to prevent damage to components during operation.

Before testing, check whether the spray nozzle’s water pipe, exhaust pipe, and air supply pipe are properly connected. Ensure the salt solution and air supply are functioning normally, the mist is discharged smoothly without leaks, and the test results are optimal.

When placing samples, maintain a certain distance between the samples and the inner walls of the chamber. Different samples should also be spaced apart to ensure uniform distribution, with the tested area covering at least 98%.

The salt spray test chamber should not be interrupted during operation. If it is necessary to observe, record, or add test solutions, the test can be briefly paused. Since the saltwater solution or acidic saltwater solution used in testing is highly concentrated and corrosive, operators must take protective measures—especially for exposed areas like hands and face—before opening the chamber door to avoid harm from salt spray.

For the same test, it is best to use the same type of samples or samples with the same testing cycle. Different materials have varying corrosion resistance, and if tested together, some samples may already show corrosion and require test termination, while others remain unaffected, making it impossible to achieve synchronized results.

The above are the key points for using a salt spray test chamber. Before operation, carefully read the instruction manual and fully understand every detail to maximize the equipment’s effectiveness.
