Quality is the vital part of a product which determines the degree of its suitability for the intended use. By applying appropriate test methods, material testing is used to determine whether a material meets the requirements to which it will be subjected in its operation phase. In this way, failures or complaints may be avoided.
National, European and international standards, rules and test specifications are the basis for comparable and reproducible results to judge a products quality.
