About this event
Understanding fault exclusion and well-tried components can make the difference between a safety design that is clear, defensible, and efficient—and one that creates avoidable uncertainty during review. This virtual session is built for people who need to apply ISO 13849 in the real world and want a sharper, more practical grasp of how these concepts affect machine safety decisions. About the Event This online event focuses on one of the more nuanced areas of ISO 13849: when fault exclusion may be justified, how well-tried components fit into a safety-related design, and where teams need to be careful about assumptions. Rather than treating the standard as a purely theoretical exercise, the session is centered on interpretation, application, and discussion. The format is designed to feel useful and direct. Expect a meetup-style learning environment where attendees can engage with the topic in a way that supports both technical understanding and professional conversation. Because the event is virtual, it is easy to attend from wherever you work while still being part of a focused, relevant discussion. This is also a strong fit for people who learn best by hearing how others approach the same problem. If you have ever paused over whether a component can reasonably be treated as well-tried, or whether fault exclusion is being applied too broadly, this event is meant to help you think more clearly about those judgment calls. What to Expect The session will explore the practical meaning of fault exclusion within the ISO 13849 framework. That includes looking at the role fault exclusion plays in safety-related parts of control systems, why it must be justified carefully, and how it can affect the overall safety case for a machine or subsystem. You can expect discussion around topics such as: What fault exclusion is intended to do in the context of ISO 13849 Where designers and assessors commonly misunderstand or overuse it How well-tried components are considered and documented The difference between a reasonable engineering argument and an unsupported assumption How these choices influence validation, review, and confidence in the final design Because this is framed as a community-oriented virtual gathering, the session is not just about receiving information. It is also about comparing interpretations, hearing practical perspectives, and asking better questions. That makes it especially helpful for attendees who are already working with machine safety requirements and want to calibrate their approach. Expect a format that balances explanation with discussion. Depending on how the conversation develops, the most valuable part may be the chance to hear how others think through edge cases, documentation challenges, and design tradeoffs that do not always have one simple answer. Why Attend ISO 13849 is widely used, but applying it well requires more than recognizing terminology. Fault exclusion and well-tried components are areas where small misunderstandings can ripple into larger issues later—during design reviews, internal approval, risk assessment updates, or external evaluation. Spending time on these topics now can save rework and reduce ambiguity later. Attending can help you build stronger judgment in places where the standard requires interpretation rather than checkbox thinking. That is especially valuable if your work touches design decisions, validation logic, compliance documentation, or cross-functional communication between engineering, safety, and quality teams. You should come away with: A clearer view of when fault exclusion may be appropriate Better instincts for evaluating claims about well-tried components More confidence discussing these concepts with colleagues and stakeholders Practical language you can use when documenting or reviewing safety decisions Exposure to how peers in the community think about the same challenges There is also real value in the networking side of the event. Topics like this benefit from shared experience, and a virtual meetup can create space for the kind of professional exchange that helps refine judgment over time. Practical Details This is an online / virtual event, which makes it accessible whether you are joining from an office, a plant, a home workspace, or while traveling between meetings. You will be able to participate without the logistics of an in-person event, while still getting focused time on a technical subject that matters. The event takes place on Tuesday, August 8 at 2:30 PM PDT. If you are attending from another time zone, plan ahead so you can join promptly and settle in before the discussion begins. A few simple ways to get the most out of the session: Come with one or two real questions from your own work Be ready to compare interpretations, not just definitions Keep notes on examples or reasoning that may help with future documentation and reviews Join from a setup where you can listen closely and participate comfortably If your work involves applying safety standards with precision—and you want a more grounded understanding of how fault exclusion and well-tried components should be approached—this session will be time well spent.
Who should attend
This event is for people who want a more practical, defensible understanding of how ISO 13849 is applied when the details matter. - You work in **machine safety, functional safety, controls, automation, or compliance** and need to make or review decisions tied to ISO 13849. - You are a **design engineer, controls engineer, safety engineer, or validator** who wants more confidence around fault exclusion and when it can legitimately be used. - You support **risk assessments, technical files, verification, or documentation** and want clearer language for justifying well-tried components. - You are part of a **cross-functional team** and need to explain these concepts to colleagues in engineering, quality, or management without oversimplifying them. - You have encountered **gray areas, conflicting interpretations, or review comments** related to these topics and want to hear how others approach them. - You value **community discussion and professional networking** with people working through similar safety and standards questions. If you are looking for practical interpretation rather than abstract theory, you will likely find this session highly relevant.
