An Introduction to Machine Safety Standard ISO 13849
Category 3 is a redundant system with monitored inputs and outputs (with other words a two channel system that has monitoring of inputs and outputs). On the other hand, the required performance level (PLr) is used in order to achieve the required risk reduction for each safety function.This CRAD focuses on assessing the adequacy of hazard category 3 documented safety analysis (DSA) and technical safety requirements (TSR) to fully comply with the .Combinaison de protection de catégorie III type 3, 4 et 5 contre les projections de liquides sous forme de jet continu, les pulvérisations de liquides non pressurisés et particules solides.
