Probability of failure

For evaluation of a safety function (PFH value) we provide you, with the Safety
Evaluation Tool (SET), a TÜV (German Technical Inspectorate) certified and free
online tool. With the help of this tool, safety functions according to IEC 62061 or
ISO 13849 can be calculated. As result you will receive a standards--compliant
report that can be integrated in the machine documentation as proof of safety.
