Element’s immersion testing services evaluate a coating’s resistance to in-service immersion conditions. This helps determine its suitability for corrosion protection during its service life.
Immersion tests form the basis of many different standards, as well as being standalone tests in their own right. The basic test involves a coated test sample being fully or partially immersed in water, at ambient conditions or at elevated temperatures and pressures. The coated samples are then assessed for any signs of degradation, including blistering, cracking, and adhesion loss.
With fully ISO 17025 compliant testing laboratories in Europe, North America and Asia, Element offers a wide range of testing for coatings evaluation including water immersion testing. From Aerospace and Oil & Gas to Transportation and Infrastructure, we deliver high quality and dependable results to our clients in many industries worldwide.For further information on water immersion testing, or to request a quote, please contact us now.
