Safety Life-Cycle Requirements for Safety Instrumented Systems: Iec 61511 Part 1 Pdf

Most recent IEC 61511-1 Ed. 2.0 b:2016 Functional safety - Safety instrumented systems for the process industry sector - Part 1: Framework, definitions, system, hardware and application programming requirementsIEC 61511-1:2016 gives requirements for the specification, design, installation, operation and maintenance of a safety instrumented system (SIS), so that it can be confidently entrusted to achieve or maintain a safe state of the process. IEC 61511-1 has been developed as a process sector implementation of IEC.

The process industry is the sector that processes mainly raw materials into new products. Oil and gas, chemicals, petrochemical, pulp and paper, and even power plants are considered process industry. The IEC 61511 standard addresses safety instrumented systems (SIS) for the process industry. A SIS is a system composed of sensors, logics solvers and final elements. A safety instrumented system can carry out one or more safety instrumented functions (SIF). Each SIF usually protects against one hazard, for example, over-pressure.

IEC 61511 address safety instrumented systems. In other words it addresses safety systems based on an instrument. Something is measured. For example pressure, flow, temperatures or what ever is needed to understand the condition of the process. There are many different names for safety instrumented systems:

This process industry was heavily involved in the development of IEC 61508 but they wanted to have a standard for their industry. In 2003 they released a lean version of IEC 61508 called IEC 61511. The IEC 61511 standard follows the philosophy of IEC 61508, but is adjusted to reflect the safety systems and terminology used in the process industry.

Yes. We have developed the Risknowlogy Certification Program. Through this program we certify safety instrumented systems, organisations and professionals according to IEC 61511 and other functional safety standards.

This Guide, written by leading experts, including from the Health & Safety Executive, provides guidance and recommendations on the application of IEC 61511 for the specification and implementation of safety instrumented systems, systems designed to bring a process plant to a safe state should a hazardous incident occur. It is intended to explain how to use the IEC 61511 standard effectively and addresses the responsibility and deliverables of organisations involved in the specification, supply and maintenance of safety instrumented systems. IEC 61511, 'Functional safety - Safety instrumented systems for the process industry sector' is now widely accepted as the state of the art for such systems. Some key aspects of EEMUA 222 are the basis of EEMUA's Functional Safety e-learning.EEMUA also offers introductory e-learning in the areas of Alarm Systems, Control Rooms, and Cyber Security.Please note: This edition of EEMUA 222 is based on the application of the IEC 61511 Edition 1 Standard and has not been revised to the most recently published IEC 61511 Edition 2 Standard.Please note EEMUA Associates receive a 25% discount off the non-member price.

Depending on where you sell your products, there are many different legal requirements that apply to your electric drives and motor controllers. These include the EC Machinery Directive 2006/42/EC or the EN ISO 13849 series of standards. In practice, however, design engineers are mainly faced with two difficulties: either there is uncertainty about which regulation applies, or it is unclear whether the regulation is applicable for the chosen solution. But this can be clarified. We can provide you with extensive support and practical information, application notes and technical FAQs, no matter what the particular product is. And our experts are always happy to help.
