About this event
If you work with machine safety, you already know that getting to a defensible MTTFd number is rarely as simple as reading one line from a datasheet. This session is built around a practical question many engineers face: how do you derive MTTFd from B10d and other component data in a way that aligns with ISO 13849 and supports real design decisions? If you want clearer reasoning, fewer assumptions, and a better handle on the numbers behind safety-related parts of control systems, this event is worth your time. About the Event This is a focused online session centered on one of the most commonly misunderstood parts of ISO 13849: translating B10d values and component reliability data into useful MTTFd calculations. Rather than treating the standard as abstract theory, the event is aimed at helping attendees connect the formulae and terminology to practical engineering work. You can expect a format that works well for a virtual gathering: a structured walkthrough of the topic, examples that make the calculations easier to follow, and space to think through where engineers often get stuck. The goal is not just to define terms, but to clarify how they are used when evaluating components and documenting safety performance. Because this is an online event, it is especially accessible if you want to join from your desk, compare notes with peers, and sharpen a specific technical skill without the overhead of travel. It also fits well for teams who want a shared reference point for discussing safety calculations internally. What to Expect The core of the event will likely revolve around the relationship between B10d, operating assumptions, and the resulting MTTFd value used in ISO 13849-based assessments. Expect a practical lens on questions such as what input data matters, how usage profiles affect outcomes, and where interpretation errors tend to happen. Topics and activities may include: A grounded explanation of what B10d represents and how it differs from other reliability metrics A step-by-step look at how MTTFd can be derived from available component data Discussion of assumptions such as cycles, mission time, operating rate, and diagnostic context Common documentation and interpretation issues when using manufacturer-provided data Time to reflect on how these calculations connect to broader ISO 13849 work This is also the kind of session where the value comes from seeing the logic laid out clearly. If you have ever inherited calculations you did not fully trust, struggled to compare data from different components, or wanted a cleaner way to explain your reasoning to colleagues, the structure of this event should help. As a community-oriented virtual gathering, there is also a networking dimension. Even in a technical topic, it is useful to hear how others approach the same problem, what assumptions they use, and where they run into friction in design reviews or compliance conversations. Why Attend The biggest reason to attend is simple: better safety calculations lead to better engineering decisions. When you understand how MTTFd is derived from B10d and related data, you are better equipped to evaluate component suitability, defend your assumptions, and avoid weak spots in safety documentation. You should leave with sharper intuition around: Which numbers are directly usable and which require interpretation How operating conditions influence reliability calculations Where overconfidence or poor assumptions can distort results How to communicate calculation logic more clearly inside your team What to watch for when relying on external component data This event is especially valuable if your work sits at the intersection of design, validation, functional safety, or compliance. A stronger grasp of these calculations helps reduce ambiguity across teams, which in turn makes reviews more efficient and decisions more consistent. Even if you already work with ISO 13849 regularly, a concentrated session on this topic can tighten your process. Standards work often becomes routine, and routine is where assumptions hide. Taking time to revisit the fundamentals can improve both the quality and defensibility of your analysis. Practical Details This is an online / virtual event, which means you can attend from anywhere with a stable internet connection. That makes it easy to join whether you are an individual practitioner, part of an engineering team, or someone exploring the topic for upcoming safety work. Date and time: Friday, August 25 10:00 AM PDT Because the session is virtual, it is a good fit for attendees who want focused technical learning in a convenient format. If this topic is directly relevant to your current projects, it may be useful to come prepared with a few notes about the types of components, duty cycles, or documentation challenges you deal with most often. If ISO 13849 calculations have ever felt more opaque than they should, this event offers a direct, practical way to make them clearer. It is a chance to strengthen a very specific part of your safety engineering toolkit while connecting with others working through the same questions.
Who should attend
This is for people who want a more practical, confident grasp of how **MTTFd** is derived from **B10d** and component data in the context of ISO 13849. - You work in **machine design, controls, automation, or functional safety** and need to make or review reliability calculations as part of your job. - You are responsible for **safety-related parts of control systems** and want clearer logic behind the numbers you use in assessments or documentation. - You review **component datasheets and manufacturer data** and want to know what can be used directly, what needs interpretation, and where assumptions can create risk. - You support **validation, compliance, CE-related work, or internal design reviews** and need a better way to explain or challenge MTTFd inputs and conclusions. - You have used ISO 13849 before but still find the **B10d-to-MTTFd step** harder than it should be, especially when real operating conditions enter the picture. - You value **peer discussion and technical networking** and want to compare how others approach reliability data, assumptions, and documentation in practice. If you have ever paused over a safety calculation and wondered whether the reasoning really holds up, you are likely the right fit for this session.
