42、ruptions 23 BS EN 61496-1:2013 8 61496-1 IEC:2012 INTRODUCTION An electro-sensitive protective equipment (ESPE) is applied to machinery presenting a risk of personal injury. It provides protection by causing the machine to revert to a safe condition before a person can be placed in a hazardous situa

43、tion. This part of IEC 61496 provides general design and performance requirements of ESPEs for use over a broad range of applications. Essential features of equipment meeting the requirements of this standard are the appropriate level of safety-related performance provided and the built-in periodic

44、functional checks/self-checks that are specified to ensure that this level of performance is maintained. Each type of machine presents its own particular hazards and it is not the purpose of this standard to recommend the manner of application of the ESPE to any particular machine. The application o

45、f the ESPE should be a matter for agreement between the equipment supplier, the machine user and the enforcing authority, and in this context attention is drawn to the relevant guidance established internationally, for example ISO 12100. This part of IEC 61496 specifies technical requirements of ele

46、ctro-sensitive protective equipment. The application of this standard may require the use of substances and/or test procedures that could be injurious to health unless adequate precautions are taken. Conformance with this standard in no way absolves either the supplier or the user from statutory obl

47、igations relating to the safety and health of persons during the use of the equipment covered by this standard. Due to the complexity of the technology used to implement ESPEs, there are many issues that are highly dependent on analysis and expertise in specific test and measurement techniques. In o

48、rder to provide a high level of confidence, independent review by relevant experts is recommended. BS EN 61496-1:201361496-1 IEC:2012 9 SAFETY OF MACHINERY ELECTRO-SENSITIVE PROTECTIVE EQUIPMENT Part 1: General requirements and tests 1 Scope This part of IEC 61496 specifies general requirements for

49、the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety related system. Special attention is directed to functional and design requirements that ensure an appropriate safety-related performance is achieved. An ESPE may include optional safety-related functions, the requirements for which are given in Annex A. The particular requirements for specific types of sensing function are given in other parts of this standard. T
