IEC 61511-1 Functional Safety - Safety Instrumented Systems for the process industry sector.
Persons, departments or organizations involved in safety life-cycle activities shall be competent to carry out the activities for which they are accountable.
When the required performance is not met, action should be taken to close the gap, ensuring safe and reliable operation. Includes training proceedings, lunch and refreshments.
The 6151-1 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. This article relies largely or entirely on a single source. A hazard and risk analysis is used to identify the required safety functions and risk reduction for specified hazardous events. From Wikipedia, the free encyclopedia. Such systems are referred to as Safety Instrumented Systems.
Please help improve this article by introducing citations to additional sources. For existing safety instrumented systems SIS designed and constructed in accordance with codes, standards, or practices prior to the issuance of this standard e. Note, however, that is not harmonized under any directive of the European Commission. The process industry sector includes many types of manufacturing processes, such as refineries, petrochemical, chemical, pharmaceutical, pulp and paper, and power.
It primarily mirrors IEC in content with the exception that it contains a grandfathering clause:. This means that in each of the member states of the European Union, the standard is published as a national standard. As a minimum, the following items should be addressed when considering the competence of persons, departments, organizations or other units involved in safety life-cycle activities:.
It contains sections that cover modifications that come along later, along with maintenance activities and the eventual decommissioning activities. This document sets the standards for safety-related system design of hardware and software. Electrical standards Safety Industrial processes.
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. Comprehension and mastering of the TUV training course material will be verified by a 4 to 6 hour proficiency examination consisting of multiple choice, and 5 working problems.
Summary of 3 Day training Question Follow-up. The process sector standard does not cover nuclear power facilities or nuclear reactors. 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.
As a minimum, the following items should be addressed when considering the competence of persons, departments, organizations or other units involved in safety life-cycle activities: List of International Electrotechnical Commission standards. Retrieved from " https: IEC covers the application of electrical, electronic and programmable electronic equipment. IEC provides good engineering practices for the application of safety instrumented systems in the process sector. Persons, departments, organizations or other units which are responsible for carrying out and reviewing each of the safety life-cycle phases shall be identified and be informed of the responsibilities assigned to them including where relevant, licensing authorities or safety regulatory bodies.
