What does EN ISO 13855 regulate and what's new?

The international standard EN ISO 13855 forms the basis for the safe design of machinery. It defines how safeguards such as light curtains, laser scanners or guards must be positioned so that people are reliably protected. The focus is on the safety distance, i.e. the distance required for machinery to stop in time before a person is endangered.

With the 2024 revision, the standards body is responding to technical developments and practical experience gained in recent years. There are key changes:
- New terms and definitions
- The basis for calculating the safety distance has been adjusted
- Additional notes on practical application

This gives design engineers, planners and inspectors a more precise and practical basis for standard-compliant implementation.
