7. Conclusion

Steel testing is essential to guarantee the safety and reliability of structures and equipment in the building and civil engineering sectors. The results of these tests can be used to select the most suitable material for a given environment, and to assess the durability of structures. Mechanical tests, such as the tensile test, are important for determining the mechanical characteristics of a material, but may be insufficient for determining a material's resistance to fracture below its elastic limit. Resilience tests, such as the Charpy test, measure the fracture toughness of materials under impact conditions. It is therefore crucial to carry out different types of test to obtain a comprehensive assessment of the properties of materials used in construction and public works.
