The causes of hazards and the technical measures taken to avoid them vary greatly. Therefore, different types of safety can be distinguished based on methods such as the potential causes of hazards.
Functional safety refers to the safety of electrical ( E ), electronic ( E ), and programmable electronic ( PE ) systems ( E/E/PE systems for short ).
Risk assessment plays a crucial role in functional safety requirements. The steps to be considered in the risk assessment and risk reduction of machines, as well as the methods for assessing and verifying safety functions, are derived from standards EN ISO 12100 , 13849-1/-2 and EN 62061. Safety integrity requirements ( PL , SIL ) are derived from risk assessment.
Functional Safety Overview
The purpose of functional safety is to always protect people and machines from danger. In Europe, the Machinery Directive lists relevant functional safety standards in the engineering field. Download Pilz's "Functional Safety" poster and learn about risk assessment and risk reduction procedures in accordance with EN ISO 12100 ; the poster uses a compact overview format. You can use two important standards derived from this so-called A standard.
EN ISO 13849-1 : Applicable to electrical, electronic, programmable electronic, hydraulic, pneumatic and mechanical systems
EN / IEC 62061 : Applicable to electrical, electronic and programmable electronic systems
The key reliability parameters for safety-related functions are the Safety Integrity Level ( SIL ) and the Performance Level ( PL ).
