The tasks carried out in the ATI service are based on the performance of technical essays using normalized rules (UNE, EN, ISO, ASTM, etc). A database with more than 800 normalized rules is available. There is high experience with essays using many of them. This database is at the disposal of all ICV personnel in the intranet. The ATI personnel updates, maintains and show how to use it using different filters (material, essay type, number, date or rule title).
