The EN/ISO 13849-1 machine safety standard uses a qualitative risk graph, or flow chart, to assign a performance level (PL), based on three criteria: severity of injury; frequency and/or exposure time to the hazard; possibility of avoiding the hazard or limiting the harm

Reference Description DC avg EN ISO 13849-1 Diagnostic coverage MTTF d EN ISO 13849-1 Mean time to dangerous failure PFH As the successor to EN 954-1, EN ISO 13849-1 is the main safety standard for the design of safety-related control systems for machinery. Performance Level In contrast to the previous standard EN 954-1, which took a deterministic (reproducible) approach, EN ISO 13849-1 is based on a probabilistic approach to assessing safety-related control systems. Amendment of EN ISO 13849-1 (October 2015) Page 4 of 9 • In Categories 2 and 3: adequate measures against CCF, and for each component DC at least "low". • In Category 4: adequate measures against CCF, and for each component DC "high".
Safe stop in upper position by clamping and one-sided pressurizing (Category 3, Category 4 attainable), possible PL a-e. Positive assessment by IFA Clamping unit 2A can be released by valve 2V with supply pressure at pressure switch 2S1 and a control system 2S2. Non-return valve 1V1 avoids exhausting ISO 13849-1, refer to “machinery directive 2006/421EC.
In contrast to the previous standard EN 954-1, which took a deterministic (reproducible) approach, EN ISO 13849-1 is based on a probabilistic approach to assessing safety-related control systems.. As well as dealing with electrical, electronic and programmable electronic systems, the standard also considers other control technologies, such as fluid power for example
085617): Usage up to category 3 according to EN ISO 13849-1, LED status indicators, Control using safety relays, 3 redundant time-delayed safety contacts, Delay time-range 1 s - 30 s, 1 auxiliary contact, Earth fault/ground fault monitoring can be selected which establishes five levels: Categories B, 1, 2, 3, and the most stringent, Category 4. In the United States, the typical level of safety circuit integrity has been called control reliability. Control reliability typically incorporates redundant control and self-checking circuitry and has been loosely equated to EN ISO 13849-1 Categories 3 and 4 EN ISO 13849-1:2008 (E) 3 Foreword The text of ISO 13849-1:2006 has been prepared by Technical Committee ISO/TC 199 “Safety of machinery” of the International Organization for Standardization (ISO) and has been taken over as EN ISO 13849-1:2008 6.2.3 Category B Contact expansion ESM-TE.., 3 safety contacts, 1 auxiliary contact, time-delay, cat.
