Corrosion Testing

Standing Up to Environmental Conditions

Corrosion testing ASTM A262Laboratory Testing Inc. offers a full array of corrosion testing services at our Philadelphia, PA (USA) area facility to ensure the performance of metals, platings and coatings, including ASTM Corrosion Testing. Accelerated Intergranular Corrosion Testing is also available to detect corrosion susceptibility in a relatively short period of time.

Our corrosion testing laboratories are just as helpful in identifying corrodents and environmental factors responsible for corrosion problems with products in service. Corrosion Testing capabilities are enhanced with an SEM/EDS system for detailed analysis and identification.

SEM/EDS Analysis

An SEM/EDS system at Laboratory Testing provides extensive corrosion testing capabilities. The system is particularly helpful in microanalysis with its high resolution imaging capabilities to a magnification of 300,000x for analyzing small areas of interest on samples. The SEM/EDS is also used for analysis of corrosion deposits to identify the corrosive agent.

Valuable Information for Product Development Through End Use

Corrosion Testing determines the resistance of materials to corrosion under certain environmental conditions, including temperature and humidity, ocean type salt water. Since all metals and alloys are susceptible to corrosion, test results can help businesses make sound decisions.

The effects of corrosion can be costly and devastating, so it generally makes sense to perform testing before damage occurs, often during product design. Corrosion analysis can also help identify a corrodent or an environmental cause, if an unexpected corrosion problem occurs.

About Test Processes

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°F to +356°F (-70°C to +180°C). 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.
