What is this standard about?
As industry becomes increasingly automated, electrical control systems are playing a larger role in machine safety. These systems are also using more complex electronics. BS EN 62061 sets out requirements for safety-related machinery control systems and how to achieve performance.
Who is this standard for?
- Machinery designers
- Control system manufacturers and integrators
- Machinery users and maintainers
- Consultants
- Regulators and notified bodies
- Anyone requiring Safety Integrity Level (SIL) classification
Why should you use this standard?
BS EN 62061 specifies functional safety requirements and makes recommendations for the design, integration and validation of safety related electrical, electronic and programmable electronic control systems (SRECS). It gives assurance that a safety related control system has the required integrity necessary for the level of risk.
The standard was developed as a derivative of IEC 61508, which introduced the concept of functional safety and applies across all industry sectors. BS EN 62061 takes the provisions, rationale and SIL (safety integrity level) classification system of IEC 61508, and interprets them for machinery control systems.
What’s changed since the last update?
BS EN 62061 has been updated to correct minor errors and update normative references and includes the following changes:
- A suggested methodology for safety integrity level (SIL) revised in Informative Annex A
- Revisions to requirements for the avoidance of systematic hardware failure
