Corrosion Testing determines the resistance of materials to corrosion under certain environmental conditions, including temperature, humidity and salt water.

About Test Process

Salt Spray Test

Our ASTM B117 Salt Spray Test, also known as Salt Fog Test, is performed according to stringent procedures. This includes testing of a material in a controlled corrosive environment which has been used to produce relative corrosion resistance information for specimens of metals and coated metals. At LTI, the test is run in a salt spray chamber with precision temperature control.

Temperature and Humidity Testing

Our environmental chamber is ideal for ensuring the reliability of products such as electronic items through exposure to thermal cycling, fast temperature cycling, and extreme temperature and humidity conditions. Temperature Testing is available in the range of $-94^{\circ} \mathrm{F} \text {to} +356^{\circ} \mathrm{F}\left(-70^{\circ} \mathrm{C} \text { to }+180^{\circ} \mathrm{C}\right)$. Humidity Testing is in the range of 10% to 95% relative humidity and simulates a damp environment. The temperature and humidity working ranges comply with DIN, ISO, MIL, IEC, DEF and ASTM testing standards.

Passivation Test

Passivation Testing evaluates the surface of corrosion-resistant steel parts by looking at surface passivity. The passivation process can remove surface contamination that can lead to rust, such as iron particles and exposed sulfides, to maximize the natural corrosion resistance of stainless steel. Upon testing, material that has been properly passivated will be virtually free of rust. The passivation test may also be useful in determining if there is a need for a treatment or protective coating on fabricated steel parts.
