Corrosion Testing

Corrosion tests are used to protect metal, stone, and other materials from deterioration. Corrosion laboratory testing involves controlled environments and exposure to high relative humidity, high temperatures, and salt atmospheres. It is necessary for commercial, industrial, military, and aerospace products to prevent permanent damage, such as metal corrosion and insulation issues.

Corrosion Testing

Corrosion tests demonstrate how to protect metal, stone, or other materials from deterioration. Corrosion causes rusting of steel or iron used in cars, water pipes, and structures. When conducting corrosion tests, one must consider the environment in which the material will be used. The most common environments include salt fog, immersion, and rapid weathering.

MIL-STD 883 Salt Atmosphere Testing, ASTM B-117 Salt Spray Testing, and RTCA DO-160 Humidity Testing are some of the corrosion test procedures. The equipment is exposed to high relative humidity, high temperatures, and salt atmospheres. After testing, the condition of the device is examined for any physical, mechanical, functional, or electrical issues.

Corrosion laboratory testing is conducted in a controlled environment, and factors such as temperature, humidity, and acidic environments are taken into account. Mass is reweighed after exposure and the initial mass is subtracted to measure the mass loss. Salt spray exposure equipment includes a fog chamber, salt solution reservoir, air supply, and other control mechanisms.

Corrosion laboratory testing is essential for commercial, industrial, military, and aerospace products. Corrosion can cause permanent damage and its negative effects include metal corroding, moving parts becoming stuck or clogged, insulation issues, contact damage, and exposed wiring. It also affects materials, conductors, insulators, chemicals, hygroscopic components, and the thermal properties of the equipment.
