A salt spray chamber creates a highly corrosive environment to test the long-term effects of salt on objects and materials.
About Our Salt Spray Chambers
The MX Series is AES's salt spray chamber. It's the only test chamber on the market that provides a 360-view into the chamber. The MX Series also features a transparent Lucite body that is impervious to corrosion.
AES salt spray test chambers maintain two very precise temperatures during operation, which is crucial for consistent salt spray concentration and test item cover. The internal testing area is held at 35°C (95°F) while the external compartment is held at 45.5°C (113.9°F).
Working volume is defined as one-tenth of the measure of each axis toward the center of the test chamber. These minimum measurements are size-dependent and define the volume within the test chamber exposed to high precision temperature uniformity.
Temperature uniformity is made up of two averages: The temperature variation in space and the temperature gradient. Temperature variation in space is the average difference between the operating temperature in the middle of the test chamber versus multiple other discretionary points around the chamber.
The temperature gradient refers to the average difference in operating temperatures between those discretionary points around the test chamber. AES ensures your devices will be tested with uniform, reliable, and repeatable environmental conditions.
The standard MX salt spray test chamber is compliant with ASTM-B117, MIL-STD-202H, MIL-STD-750F, MIL-STD-810G standards for corrosion testing and can be modified to meet MIL-STD-883K and MIL-STD-19500.
AES's salt spray test chambers feature a high-reliability thermostatic temperature controller that maintains the salt solution at a preset temperature in a reservoir within a double-wall construction. The salt solution is introduced into the test chamber through an atomizing nozzle, which can be calibrated by AES to perform to MIL-STD-19500B, paragraph 40.8, and other specifications.
Salt Spray Equipment
AES supplies salt spray test chambers with an atomizing nozzle, which can be used to test to the MIL-STD-19500B 40.8 specification. The atomizing nozzle ensures the salt solution is introduced to the test environment evenly and at the proper concentration.
Salt Spray chambers are commonly used to evaluate the corrosive properties of:
- Phosphated surfaces (with subsequent paint/primer/lacquer/rust preventive)
- Zinc and Zinc-alloy plating (see also electroplating)
- Electroplated chromium, nickel, copper, and tin
- Coatings not applied electrolytically (such as zinc flake coatings)
- Organic coatings
- Paint coatings
