While IEC does apply to equipment using pneumatic or hydraulic systems to manipulate final elements, the standard does not cover the design and implementation of pneumatic or hydraulic logic iec 61511-1. Retrieved from ” https: IEC is generic functional safety standard, providing the framework and core requirements for sector specific standard. IEC covers the design and management requirements for SISs throughout the entire safety life cycle. An SIS may implement one or more safety instrumented functions Iec 61511-1which are designed and implemented to address a specific process hazard or hazardous iiec.

List of International Electrotechnical Commission standards. Iec 61511-1 process sector ifc does not cover nuclear 6511-1 facilities or nuclear reactors. Note, however, that is not harmonized under any directive of the European Commission.

An SIS is composed of a separate and independent combination of sensors, logic solvers, final elements, and support systems that are designed and managed to achieve a specified safety integrity level SIL. Articles needing additional references from Iec 61511-1 All articles needing additional references.

Field data are collected through operational and mechanical integrity program activities to assess actual SIS performance.

Such systems are referred to as Safety Instrumented Systems. A hazard and risk analysis is used to identify ie required safety functions and risk reduction for specified hazardous events.

When the required performance is not met, action should be taken to close the gap, ensuring safe and reliable operation. This document sets the standards for safety-related system design of hardware and software. Electrical standards Safety Industrial processes. The title of the standard is ” Iec 61511-1 safety – Safety instrumented systems for the process ie sector “.

For existing safety instrumented systems SIS designed and constructed in accordance with codes, standards, ieec practices prior to the issuance of this standard e.

Safety functions ie to the SIS are safety instrumented functions; the allocated risk reduction is related to the SIL. The essential roles of the various personnel assigned responsibility for the SIS should be defined and procedures developed, as necessary, to support the consistent execution of their responsibilities.

It starts in the earliest phase of iec 61511-1 project and continues through startup.
