Achieve a higher safety performance level with EN ISO 13849-1

If you do not consider yourself as one of the early adopters of ISO 13849-1, is there still time to change to comply to the machine safety standards current requirements, and what does it involve?

05/09/2013


Over the past few years, safety has become one of the dominant factors that impact product design processes. European guidelines for machine safety have played a major role in reducing injuries and are bringing new requirements for product and component developers in their goal of working toward creating a better and safer working environment.

At the end of 2011, EN ISO 13849-1:2006 “Safety of machinery, Safety-related parts of control systems, Part 1: General principles for design” took effect. The EN 954-1 (CAT B, CAT 2, CAT3 & CAT4) was replaced by ISO13849-1, because programmable electronic systems were considered insufficiently; there was no consideration for direct connection between risk minimization, category, or complexity. Also, time response (e.g., testing intervals, lifecycles) and the failure probability of components (e.g., Common Cause Failures) were not considered. Therefore, due to all these aspects, EN 954-1 did not represent the state of technology anymore.

EN ISO 13849-1 addresses the programmable electronic safety devices that are being used increasingly in modern machines. The standard also provides a quantitative approach to risk assessment and safety validation. This ensures that safety is not solely a matter of component reliability, but also relies on common-sense safety principles such as redundancy, diversity, and fail-safe behavior. Under this standard, the risk assessment for a given safety function will yield a performance level (PL). This helps eliminate both over- and under-engineering, a costly or risky result of EN 954-1’s limitations.

Safety designers should start designing products using EN ISO 13849-1. It improves safety and the experience of working with the new requirements, and will have much greater long-term benefits than using EN 954.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
