Korrosionsprovning

Korrosionsprovning, or corrosion testing, refers to a set of procedures used to evaluate the resistance of materials—primarily metals and alloys—to corrosion under specific environmental conditions. This testing is essential for determining how materials will perform in real-world applications, such as in constructing buildings, vehicles, pipelines, and industrial equipment, where exposure to moisture, salts, acids, or other corrosive agents can compromise integrity and safety.

There are several types of corrosion tests, including accelerated and natural exposure methods. Accelerated tests, such as salt spray (fog) tests, involve exposing samples to controlled corrosive environments in a laboratory setting to predict long-term behavior within a shorter period. Common tests also include cyclic corrosion tests, humidity tests, and immersion tests, each tailored to simulate specific environmental factors.

The selection of a corrosion testing method depends on the material, intended environment, and relevant standards or regulations. Results from these tests provide crucial data on corrosion rate, form of corrosion (e.g., pitting, uniform, crevice), and the effectiveness of protective coatings or treatments. This information supports material selection, quality control, and the development of corrosion-resistant materials or coatings.

Corrosion testing is governed by international standards such as ISO, ASTM, and EN specifications, ensuring consistency and comparability of results across industries. The process plays a vital role in extending product lifespan, maintaining safety standards, and reducing maintenance costs by enabling more durable material choices and protective strategies.
