ASTM G31 Laboratory Immersion Corrosion Testing of Metals

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM G31 testing. This standard uses dip corrosion testing to determine a material's resistance to an aggressive, aqueous environment.

Standard laboratory corrosion coupons are used to determine weight loss due to corrosion. The ASTM G31 test method normalizes corrosion rates to units of time, typically mm/year or miles/year (mpy). Test terms vary, but results are usually available within a 24-hour, 10- or 20-day exposure cycle. Test temperature and oxygen availability variables are also test-specific.

After testing, gravimetric analysis provides the corrosion weight. Surface analysis can also be done with stereo microscopy or scanning electron microscopy to further investigate post-test morphology.

The application of laboratory corrosion exposure testing gives manufacturers and suppliers an enhanced advantage over the limitations of ingredients used in manufactured products before they are purchased or incorporated into a larger component of the final product.

This forward-thinking approach not only limits the time, energy and revenue spent on poor quality products, but also limits the risk of losing market position, clientele and customers due to poor product performance.

In summary, accelerated corrosion testing is used to induce corrosion and failure in a relatively short period of time compared to corrosion produced as a natural occurrence. This gives decision makers the tools to fine-tune, redesign using alternative materials, or completely eliminate a particular supplier with poor quality products.
