Control System Design Principles and Standards According to ISO/EN 13849

Safety-Related Machinery Control and HMI Systems with ISO 13849 and IEC 62061

ISO/EN 13849 Standard

The standard applies to a safety-related system and also be applied to the component parts of the system. The standard addresses system integrators, machine builders, control panel builders, as well as component manufacturers and suppliers. This standard provides requirements for the design and integration of safety-related parts of control systems, including some software aspects. It can be adapted to suit both advanced and entry levels of functional safety competence. It can be tailored to the specific needs of a specific audience which determines the length of the course.

Key Machine Safety Design Standards

Increasingly, large multinational enterprises are requiring a single machine design that can be shipped to any of their facilities. Designing machines to meet the EU Machinery Directive is the most practical way to meet this requirement; using EN ISO 13849-1 to demonstrate compliance with the directive is the easiest way to verify the design of the safety system.
