Abstract The article presents a method for determining the performance level (PL) on the basis of the PN-EN ISO 13849-1 standard, which is harmonized with the machinery directive 2006/42/EC. The risk assessment and risk reduction criteria, according to PN-EN ISO 12100, were briefly characterized. The focus was put on determining the required performance level PLr on the basis of a risk graph. The method was presented how to use a safety function composed of input-, logicaland execution subsystems. It was demonstrated how to determine the achieved PL for a safety function composed of hardware elements on the basis of a safety category, mean time to dangerous failures (MTTFd), diagnostic coverage (DC), and immunity to common cause failures (CCF).
