Calculate failure probabilities quickly and easily on our website! Simply type in your parameters, and our free tool does the work for you. All relevant formulas are stored directly in our system. Choose between a PFD calculation in accordance with VDI/VDE 2180 and EN 61508 or a PFH calculation according to EN 61508.
Small tooltips for field functions make the site easy to use. Simply hover the cursor over an info icon. Additionally, you can opt in and have the calculation results automatically sent to your email address as a PDF file.
Feel free to contact us if you are looking for support and product solutions for your functional safety projects. We look forward to your inquiry!
The values that appear in the input fields at the start of the program are examples to demonstrate the operation and function of the program. Please replace these values with the actual values of the respective safety function.
The spreadsheet for calculating the PFD/PFH according to EN 61508 and VDI/VDE 2180 has been carefully prepared. Nevertheless, we expressly state that the calculated PFD/PFH values only apply in compliance with the above-noted rules and boundary conditions. No liability is assumed for the calculated results, and no claims are made about their correctness; the calculation of the PFD/PFH of the respective safety function is the sole responsibility of the user.
