This workshop introduces the general aspects of functional safety and its principles with reference to the FS standard IEC 61508, including relevant terminology to facilitate understanding. There are no prerequisites for the course, and the target audience includes various management teams (general, product, project and quality) as well as marketing and sales staff.
