Introduction to standards for programmable systems; 9.1 Introduction; 9.2 Objectives9.3 Outline of IEC 61508Practical Machinery Safety aims to provide you with the knowledge to tackle machinery safety control problems at a practical level whilst achieving compliance with national and international standards. The book highlights the major international standards that are used to support compliance with EU regulations and uses these standards as a basis for the design procedures. It looks at the risk assessment processes used to identify hazards and to quantify the risks inherent in a machine. It introduces the concepts of safety categories as defined by standard EN954-1 (Safety of MPractical professional books from Elsevier.MachinerySafety regulationsMachinerySafety appliancesDigital control systemsIndustrial safetyMachinerySafety regulations.MachinerySafety appliances.Digital control systems.Industrial safety.621.80289Macdonald Dave1942-627440MiAaPQMiAaPQMiAaPQBOOK9911006895403321Practical machinery safety4390420UNINA
