    The present experimental work aims to verify the mechanical strength of the containers manufactured by the company ECUAMATRIZ CIA LTDA. using the finite element method, based on the tests described in the UNE EN 12574-2 standard due to the need to check the criteria established by said regulations. Within the tests examined, the following are mentioned: the ballistic impact, nominal load resistance test, lateral impact test, frontal impact, corners, and fatigue analysis due to the elevation of the container, each of them being governed by the specifications within UNE EN 12574-2. Initially, a simulation model is generated by selecting a material model according to the mechanical properties of galvanized steel A 653. By means of the ballistic test deformation profiles with an average of 1.55 mm were obtained, with which the model validation was carried out. simulation obtaining a maximum error of 11% and a minimum of 7%. For the impact test of faces and corners, an inclined surface was used inside the Ecuamatriz facilities according to kinematic calculations, the impact distances were established so that the speeds corresponded to the required in the norm, obtaining a zero deformation for the real test while in the simulation a maximum plastic deformation of 0.06 was obtained in a time of 0.13 s. For the practical part of the elevation test, the dimensions determined by the UNE EN 12574-1 were used, with which, we can verify the variation of the functional dimensions have a maximum error of 1.18%, within the simulation the container resists 1e6 cycles for both cases of study.
