This article explores the requirements for safety related control systems meeting ISO 13849 – 1 Category 2 requirements. “Gotcha!” points in the definition are highlighted to help designers avoid this common pitfalls.Read More
IEC and ISO have published a new guide to help users select between ISO 13849 – 1 and IEC 62061. This new Technical Report will replace Table 1 in both standards.Read More
In this excellent article from Rockwell Automation’s The Journal, Mike Miller and Wayne Solberg explain how EN ISO 13849 – 1 and EN IEC 62061 mesh for machine builders.
Well worth the read in my opinion!
This article expands on the first in the series “Interlock Architectures – Pt. 1: What do those categories really mean?”. Learn about the basic circuit architectures that underlie all safety interlock systems under ISO 13849 – 1, and CSA Z432 and ANSI RIA R15.06.Read More
In 1995 CEN published an important standard for machine builders – EN 954 – 1, Safety of Machinery – Safety Related Parts of Control Systems – Part 1: General Principles for Design. This standard set the stage for defining control reliability in machinery safeguarding systems, introducing the Reliability categories that have become ubiquitous. So what do these categories mean, and how are they applied under the latest machinery standard, ISO 13849 – 1?Read More
