Electrical, electronic and programmable electronic systems, such as emergency shut down systems and railway signalling systems, increasingly carry out safety functions to guard workers and the public against injury or death and the environment against pollution. The international standard IEC 61508 has been developed as a generic standard that applies to all these systems irrespective of their application. IEC 61508 is seen by many professionals as complex. This book overcomes that complexity by introducing the standard in the context of safety in general before moving on to provide practical advice about implementing it and obtaining certification. It also explains how IEC 61508 relates to second tier standards and related guidance, such as IEC 61511, 61513, UKOOA, ISA S84.01 and DIN standards, among others. Throughout the text, the authors illustrate their explanations with examples to which the answers are supplied in the appendix. Four case studies with further exercises set the information in context. Templates and checklists for drawing up your own implementation plan and information on self-certification are also provided. As Functional Safety, the standard, is applicable to many industries, Functional Safety, the book, in its previous edition has proved to be an invaluable reference for professionals from a variety of industries, such as project/instrumentation/design/control engineers as well as safety professionals in oil and gas, chemical, rail, power generation, nuclear, aircraft, and automotive industries. The new edition includes a new chapter on IEC 61511, the process sector standard, published since the first edition. The text has been updated throughout in light of the authors’ recent experience and two case studies have been added. Dr. David J Smith, BSc, PhD, CEng, FIEE, HonFSaRS, FIQA, MIGasE, has been directly concerned with reliability, safety and software quality for 30 years. He has written a number of books on the subject as well as numerous papers. His PhD thesis was on the subject of reliability prediction accuracy and common cause failure. He chairs the IGasE panel which develops its guidelines on safety-related systems (now in its third edition). He has also made contributions to IEC 61508. Kenneth G. L. Simpson, MPhil, FIEE, FInstMC, MIGasE, has been associated with safety-related systems design and also with their assessment for 25 years. He is a member of the IEC 61508 drafting committee and also of the I Gas E panel which writes the gas industry guidance. Following a career in aerospace, Ken has spent 20 years in the control system industry and is a Director of Silvertech International plc, a leading designer of safety and control systems. He has written a number of papers on the topic and gives frequent talks.

This ebook explains what SIL and functional safety means in a nutshell. The book is intended for everybody who is new to functional safety and SIL and wants to have a full overview without being lost in the details. It is excellent for managers that need to understand quickly what functional safety is all about and how it will influence the work of their employees and their products and/or services. It is excellent for engineers and professionals that want to get started with functional safety and understand the big picture before going into detail. Many standards, guidelines and other publications exist that talk about functional safety. All of them with their own level of detail. This book does not to go into the details of what has to be done according to what standard and what not. It explains main functional safety concepts so that you know everything you need to know to get started. Functional safety is not rocket science and once you understand it and applied it a few times in practice you will notice it is just good engineering practice. This book tries to explain that good engineering practice. Functional safety standards can be confusing and contradicting at times and sometimes they require things that make no sense. You do not need to understand the standards in order to apply and be good at functional safety. If you understand the concepts explained in this book you can apply functional safety into your organisation and to your products, with or without following the exact requirements of standards. Actually once you understand how functional safety works you most likely will go beyond what standards say and create your own functional safety organisation of excellence. And if you do that, well then you are well on your way in becoming a longtime winner as suppose to a short term fuse.

The EN ISO 13849-1 standard, “Safety of machinery – Safety-related parts of control systems”, contains provisions governing the design of such parts. This report is an update of BGIA Report 2/2008e of the same name. It describes the essential subject-matter of the standard in its third, revised 2015 edition, and explains its application with reference to numerous examples from the fields of electromechanics, fluidics, electronics and programmable electronics, including control systems employing mixed technologies. The standard is placed in its context of the essential safety requirements of the Machinery Directive, and possible methods for risk assessment are presented. Based upon this information, the report can be used to select the required Performance Level PLr for safety functions in control systems. The Performance Level PL which is actually attained is explained in detail. The requirements for attainment of the relevant Performance Level and its associated Categories, component reliability, levels of diagnostic coverage, software safety and measures for the prevention of systematic and common-cause failures are all discussed comprehensively. Background information is also provided on implementation of the requirements in real-case control systems. Numerous example circuits show, down to component level, how Performance Levels a to e can be engineered in the selected technologies with Categories B to 4. The examples provide information on the safety principles employed and on components with well-tried safety functionality. Numerous literature references permit closer study of the examples provided. The report shows how the requirements of EN ISO 13849-1 can be implemented in engineering practice, and thus makes a contribution to consistent application and interpretation of the standard at national and international level.

This book highlights the current challenges for engineers involved in product development and the associated changes in procedure they make necessary. Methods for systematically analyzing the requirements for safety and security mechanisms are described using examples of how they are implemented in software and hardware, and how their effectiveness can be demonstrated in terms of functional and design safety are discussed. Given today’s new E-mobility and automated driving approaches, new challenges are arising and further issues concerning “Road Vehicle Safety” and “Road Traffic Safety” have to be resolved. To address the growing complexity of vehicle functions, as well as the increasing need to accommodate interdisciplinary project teams, previous development approaches now have to be reconsidered, and system engineering approaches and proven management systems need to be supplemented or wholly redefined. The book presents a continuous system development process, starting with the basic requirements of quality management and continuing until the release of a vehicle and its components for road use. Attention is paid to the necessary definition of the respective development item, the threat-, hazard- and risk analysis, safety concepts and their relation to architecture development, while the book also addresses the aspects of product realization in mechanics, electronics and software as well as for subsequent testing, verification, integration and validation phases. In November 2011, requirements for the Functional Safety (FuSa) of road vehicles were first published in ISO 26262. The processes and methods described here are intended to show developers how vehicle systems can be implemented according to ISO 26262, so that their compliance with the relevant standards can be demonstrated as part of a safety case, including audits, reviews and assessments.

About This Book If you want to achieve functional safety on a project, technically, the hardware and software must be SIL-compliant. But how do you achieve that? With functional safety management. FSM is at the heart of all SIL projects. If you understand FSM and you apply it correctly, every project will achieve compliance and, thus, SIL. In this book, the author explains the five core concepts that are at the basis of achieving functional safety. If you master these five concepts, your SIL projects will: - Will be completed faster. - Will be completed within budget. - Lead to profitable products and services. - Have more competent employees. Functional safety management is a requirement in all functional safety standards. Your product, service, solution, operation, maintenance and repair depend on it. You could not claim compliance with the standards if you did not implement functional safety management. Yet many companies do. This is no problem as long as no accidents happen.

The need to specify quantitative safety targets for overall systems, and for their separate protection sub-systems, has grown rapidly over the last ten years. This feature has become known as Functional Safety and numerous standards and guidelines have emerged, most of which incorporate the idea of safety-integrity levels (SILs). The quantified target (either a failure rate or a probability of failure on demand) determines which of four target SILs is called for. The higher the SIL then the more onerous the qualitative requirements to be observed during the life-cycle. Thus safety-integrity is addressed from two points of view: Meeting the numerical failure rate target Meeting the qualitative requirements for the SIL in question The IEC Standard 61508, Functional Safety, has become the umbrella document under which most other guidelines are now regarded as "2nd tier guidance." Functional Safety: A Straightforward Guide to IEC 61508 and Related Standards is based primarily on understanding that standard and provides a straightforward guide to the essentials. Dr David J Smith BSc, PhD, CEng, FIEE, HonFSaRS, FIQA, MIGasE has been directly concerned with reliability, safety and software quality for 30 years. He has written a number of books on the subject as well as numerous papers. His PhD thesis was on the subject of reliability prediction accuracy and common cause failure.
