IEC covers the application of electrical, electronic and programmable electronic equipment. Safety functions allocated to the SIS are safety instrumented ice the allocated risk reduction is related to the SIL.

It primarily mirrors IEC iev content with the exception that it contains a grandfathering clause:. 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 is 615111-1 functional safety standard, providing the framework and core requirements for sector specific standard. The title of the standard is ” Oec safety – Safety instrumented systems for the process industry sector “. It starts in the earliest phase of a project and continues through startup. The content of these national publications is identical to that of IEC Field data are collected through operational and mechanical integrity program activities to assess actual SIS performance.


IEC standard is a technical standard which sets out practices in the engineering of systems that ensure the safety of an industrial 6151-1 through the use of instrumentation. Articles needing additional references from March All articles needing additional references. This page was last edited on 8 Mayat Such systems are referred to as Safety Instrumented Systems. Note, however, that is not harmonized under any directive of the European Commission. Relevant discussion may be found on the talk page.

The process industry sector includes many types of manufacturing processes, such as refineries, petrochemical, chemical, pharmaceutical, pulp and paper, and power. This means that in each of the member states of the European Union, the standard is published as a national standard.

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

Electrical standards Safety Industrial processes. Retrieved from ” https: 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. 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. IEC provides good engineering practices for the application of safety instrumented systems in the process sector. A hazard and risk analysis is used to identify the required safety functions and risk reduction for specified hazardous events.

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. List of International Electrotechnical Commission standards. 6151-11 IEC does irc 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.

This document sets the standards for safety-related system design of hardware and software.

Functional Safety Standards – IEC vs. IEC | exida

For 61511-1 safety instrumented systems SIS designed and constructed in accordance with codes, standards, or practices prior to the issuance of this standard e. When the required performance is not met, action should be taken to close the gap, ensuring safe and reliable operation. It contains sections that cover modifications that come along later, along with maintenance activities and the eventual decommissioning activities.
