Tensile testing is arguably the most fundamental mechanical test performed on metallic materials. It determines how a material will react to forces being applied in tension. By pulling a metal specimen apart, engineers can derive critical data points such as , Tensile Strength , and Elongation . En 10002-1 Pdf

Between 2009 and 2016, CEN adopted the international standard ISO 6892-1 to replace the older EN 10002 series. The goal was to align European testing methods with global ISO standards, eliminating redundant national rules.
