Iec 61511-1

IEC covers the design and management requirements for SISs throughout the entire safety life cycle. IEC provides good engineering practices for the application of safety instrumented systems in the process sector. Safety functions allocated to the SIS are safety instrumented functions; the allocated risk reduction is related to the SIL.

IEC - Wikipedia

This means that in each of the member states of the European Union, the standard is published as a national standard. IEC is generic functional safety standard, providing the framework and core requirements for sector specific standard.

By using this site, you agree to the Terms of Use and Privacy Policy. IEC standard is a technical standard which sets out practices in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation.

Relevant discussion may be found on the talk page. It starts in the earliest phase of a project and continues through startup. Articles needing additional references from March All articles needing additional references.

When the required performance is not met, action should be taken to close the gap, ensuring safe and reliable operation. It primarily mirrors IEC in content with the exception that it contains a grandfathering clause:. 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 solvers. IEC covers the design and management requirements for SISs throughout the entire safety life cycle.

This standard defines the functional safety requirements established by IEC in process industry sector terminology.

Safety functions allocated to the SIS are safety instrumented functions; the allocated risk reduction is related to the SIL. Electrical standards Safety Industrial processes.

This document sets the standards for safety-related system design of hardware and software. The content of these national publications is identical to ief of IEC For existing safety instrumented systems SIS designed and constructed in accordance with codes, standards, or practices prior to the issuance of this standard e.

Please help improve this article by introducing citations to additional sources. The process industry sector includes many types of manufacturing processes, such as refineries, petrochemical, chemical, pharmaceutical, pulp and paper, and power.

The essential roles of the various personnel assigned responsibility kec the SIS should be defined and procedures developed, as necessary, to support the consistent execution of their responsibilities. It contains sections that cover modifications that come along later, along with maintenance activities and the eventual decommissioning activities.

Field data are collected through operational and mechanical integrity program activities to assess actual SIS performance. An 6151-1 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 ied integrity level SIL.

List of International Electrotechnical Commission standards. This page was last edited on 8 Mayat A hazard and risk analysis is used to identify the required safety functions and risk reduction for specified hazardous events.

Such systems are referred to as Safety Instrumented Systems. The title of the standard is " Functional safety - Safety instrumented systems for the process industry sector ".

IEC provides good engineering practices for the application of safety jec systems in the process sector.

An SIS may implement one or more safety instrumented functions SIFswhich are designed and implemented to address a specific process hazard or hazardous event. IEC covers the application of electrical, electronic and programmable electronic equipment. From Wikipedia, the free encyclopedia.

The process sector standard does not cover nuclear power facilities or nuclear reactors. This article relies largely or entirely on a 6511-1 source.
