Organization for Standardization (ISO) the International Electrotechnical Commission (IEC). These are designated EN ISO 13849-1 and EN 62061 respectively. EN 62061 is applicable only to electrical control systems. Both replace the old standard EN 954-1, which will become obsolete on December 31, 2011, after a 3+2-year allowable transition period.
A central part of EN ISO 13849-1:2008 is to choose an appropriate category for the identified safety functions. Categories were used also in the earlier machinery safety standard EN 954-1:1996. The report describes in detail the meaning of each category and also gives an example of a category 2 safety function.
The European Standard EN ISO 13849-1:2015 has the status of a Swedish Standard. EN ISO 13849-1: Performance Level (PL) Ju högre risk desto högre är kraven på styrsystemen. Risksituationen bedöms efter en skala med fem steg, så kallade Performance Levels (PL), från PL ”a” (låg) till ”e” (hög). Den nödvändiga PL fastställs inom ramen för riskbedömningen enligt EN ISO 12100 och EN ISO 13849-1. Se hela listan på machinerysafety101.com EN ISO 13849-1 is the most important standard for regulating the basic principles and performance required of a safety control system for machines and devices. This standard was greatly revised in November 2006. This revision has caused major changes in the fundamentals of safety system design.

Non-return valve 1V1 avoids exhausting Category 3 & 4 — Redundant system. Redundant system can be constructed easily. As the dual residual pressure release valve is used, if one of the valves fails to operate, the other one releases residual pressure. Products Validated to ISO-13849 Safety Standard.
