Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Embedded Software Development for Safety Critical Systems written by Chris Hobbs and published by CRC Press. This book was released on 2017-09-07 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: "I highly recommend Mr. Hobbs' book." - Stephen Thomas, PE, Founder and Editor of FunctionalSafetyEngineer.com Safety-critical devices, whether medical, automotive, or industrial, are increasingly dependent on the correct operation of sophisticated software. Many standards have appeared in the last decade on how such systems should be designed and built. Developers, who previously only had to know how to program devices for their industry, must now understand remarkably esoteric development practices and be prepared to justify their work to external auditors. Embedded Software Development for Safety-Critical Systems discusses the development of safety-critical systems under the following standards: IEC 61508; ISO 26262; EN 50128; and IEC 62304. It details the advantages and disadvantages of many architectural and design practices recommended in the standards, ranging from replication and diversification, through anomaly detection to the so-called "safety bag" systems. Reviewing the use of open-source components in safety-critical systems, this book has evolved from a course text used by QNX Software Systems for a training module on building embedded software for safety-critical devices, including medical devices, railway systems, industrial systems, and driver assistance devices in cars. Although the book describes open-source tools for the most part, it also provides enough information for you to seek out commercial vendors if that’s the route you decide to pursue. All of the techniques described in this book may be further explored through hundreds of learned articles. In order to provide you with a way in, the author supplies references he has found helpful as a working software developer. Most of these references are available to download for free.

Download or read book Dependable Computing EDDC 3 written by Jan Hlavicka and published by Springer. This book was released on 2003-06-26 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of creating the European Dependable Computing Conference (EDCC) was born at the moment when the Iron Curtain fell. A group of enthusiasts, who were pre viously involved in research and teaching in the ?eld of fault tolerant computing in different European countries, agreed that there is no longer any point in keeping pre viously independent activities apart and created a steering committee which took the responsibility for preparing the EDCC calendar and appointing the chairs for the in dividual conferences. There is no single European or global professional organization that took over the responsibility for this conference, but there are three national in terest groups that sent delegates to the steering committee and support its activities, especially by promoting the conference materials. As can be seen from these materi als, they are the SEE Working Group “Dependable Computing” (which is a successor organizationof AFCET)in France,theGI/ITG/GMATechnicalCommitteeonDepend ability and Fault Tolerance in Germany, and the AICA Working Group “Dependability of Computer Systems” in Italy. In addition, committees of several global professional organizations, such as IEEE and IFIP, support this conference. Prague has been selected as a conference venue for several reasons. It is an easily accessible location that may attract many visitors by its beauty and that has a tradition in organizing international events of this kind (one of the last FTSD conferences took place here).

Download or read book Design and Construction of Laboratory Gas Pipelines written by James Moody and published by CRC Press. This book was released on 2019-03-13 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume, Design and Construction of Laboratory Gas Pipelines: A Practical Reference for Engineers and Professionals, focuses on design and installation of laboratory gas pipelines. It instructs design engineers, laboratory managers, and installation technicians on how to source the information and specifications they require for the design and installation of laboratory gas systems suitable for their intended use. The current use of specifications predominantly taken from medical gas standards for this type of work is not always suitable; these standards are for use with medical grade gases that have a purity level of 99.5%. The purity levels required in laboratories, however, start at 99.9% for general industrial use through to 99.9995% (Ultra High Purity (UHP)) and higher. Regular medical gas standards are also unsuitable for use with the oxidizing, flammable, and, in some instances, toxic gases that are regularly encountered in laboratories. As need for gas purity increases, the methodology used to design a piping system must vary to meet those parameters, and this reference provides the necessary information and resources. There are no comprehensive single sources of technical references currently available in this market, states the author, and the generally supplied specifications provided to the construction industry are usually generic and not specifically targeted for the gases in use. The results provide extremely poor quality designs and, in some instances, unusable systems. With over 40 years of specialization in the industry from project management to systems design, testing, and commissioning of projects with values in excess of $15 million, the author comprehensively fills that gap with this rich resource. Key features • provides information on types of laboratories that use laboratory gases and the equipment needed • explains the various methods of construction and the materials used to ensure that the purity of the gases remains as supplied from the manufacturers • incorporates the design methodology used to meet the various requirements of the laboratory and the information required to ensure that the correct engineering is provided • presents information on the purity levels of the gases and the data on the equipment used for pipelines and compatibility issues • presents an example of a simple laboratory gas specification that provides guidelines on the information necessary to provide a set of design documents

Download or read book Risk Assessment written by Valentina Svalova and published by IntechOpen. This book was released on 2018-02-28 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment is one of the main parts of complex systematic research of natural and man-made hazards and risks together with the concepts of risk analysis, risk management, acceptable risk, and risk reduction. It is considered as the process of making a recommendation on whether existing risks are acceptable and present risk control measures are adequate, and if they are not, whether alternative risk control measures are justified or will be implemented. Risk assessment incorporates the risk analysis and risk evaluation phases. Risk management is considered as the complete process of risk assessment, risk control, and risk reduction. The book reflects on the state-of-the-art problems and addresses the risk assessment to establish the criteria for ranking risk posed by different types of natural or man-made hazards and disasters, to quantify the impact that hazardous event or process has on population and structures, and to enhance the strategies for risk reduction and avoiding.
