Scope (English)

This standard to be used only after a thorough understanding of IEC 61508-1, which provides the overall framework for the achievement of functional safety and applies to all elements within an E/E/PE safety-related system. This standard specifies how to refine the E/E/PE system safety requirements specification, developed in accordance with IEC 61508-1. This standard specifies how to refine the E/E/PE system safety requirements specification, developed in accordance with IEC 61508-1, into the E/E/PE system design requirements specification. This standard specifies the requirements for activities that are to be applied during the design and manufacture of the E/E/PE safety-related systems except software, which is dealt with in IEC 61508-3. These requirements include the application of techniques and measures that are graded against the safety integrity level, for the avoidance of, and control of, faults and failures and specifies the information necessary for carrying out the installation, commissioning and final safety validation of the E/E/PE safety-related systems.
