Frequently Asked Questions

Have Question? We are here to help

What is a salt spray chamber?

A salt spray chamber, also known as a corrosion chamber or salt fog chamber, is an environmental testing system used to evaluate a material's or product's resistance to corrosion. By exposing test specimens to a controlled salt-laden atmosphere, manufacturers can accelerate corrosion processes and assess long-term durability in a fraction of the time required under natural conditions.

What is the purpose of salt spray testing?

Salt spray testing is used to evaluate corrosion resistance, coating effectiveness, material durability, and product performance. The test helps manufacturers identify potential weaknesses, compare protective finishes, and improve product reliability before deployment in the field.

What is ASTM B117 testing?

ASTM B117 is one of the most widely recognized standards for salt spray testing. It outlines procedures for creating and maintaining a controlled salt fog environment to evaluate the corrosion resistance of materials, coatings, and finished products.

Why choose an AES MX Series Salt Spray Chamber?

The AES MX Series is engineered to deliver accurate and repeatable corrosion testing in a completely self-contained corrosive environment. The chamber prevents the introduction of external contaminants into the test area while providing exceptional visibility of the device under test, allowing users to monitor testing progress without compromising test integrity.

How often should a salt spray chamber be calibrated?

Calibration frequency depends on quality requirements, industry standards, and internal procedures. AES recommends annual calibration and preventive maintenance to ensure testing accuracy, repeatability, and compliance but also to keep your equipment running for many years.
