In the current ISO 13849-1 standard, the criteria for the required performance level PLr (Required Performance Level) for the applicable risk Category 3 적용.

ISO 13849-1（機械安全 - 控制系統的安全相關部分 - 設計通則）為國際標準，於 2006 年修訂。. 修訂背景：在構成控制系統其安全相關部分的安全機械中，已採用如電晶體和 MOS-FET 等半導體零件，這代表控制方法已從硬體佈線控制方式，改變成軟體控制方式。. 在傳統的類別思維中，採用機械安全裝置和含強制導向觸點之繼電器的系統架構（結構）決定了安全，但由於零件

EN ISO 13849-1 is based on the familiar categories from EN 954-1:1996. It examines complete safety functions, including all the components invol- ved in their design. EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions.

The design is made with the Functional safety design tool. Abbreviations Abbr.

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. This document was prepared to help explain 3 Under EN ISO 13849-1, the consideration of safety starts with the risks associated with the machine, its function and its operation.

The required PL is determined and assigned as part of the risk assessment in accordance EN ISO 13849-1. EN ISO 13849-1/-2: Safety of machinery – Safety-related parts of control systems 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.

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
