27、ts. IEC Publication61496-1 is copyrighted by the IEC.This is the UL Standard for Safety for Electro-Sensitive Protective Equipment, Part 1: GeneralRequirements and Tests. This UL Part 1 is to be used in conjunction with the appropriate UL Part 2, whichcontains clauses to supplement or modify the cor
28、responding clauses in Part 1, to provide relevantrequirements for each type of product.The text, figures and tables of IEC Publication Safety of Machinery Electro-Sensitive ProtectiveEquipment Part 1: General Requirements and Tests, IEC 61496-1 copyright 1997 are used in thisStandard with the consen
29、t of the IEC and the American National Standards Institute (ANSI). The IECcopyrighted material has been reproduced with permission from ANSI. ANSI should be contactedregarding the reproduction of any portion of the IEC material. The IEC Foreword and Introduction are nota part of the requirements of

The difference type is noted on the first
34、lineof the National Difference in the standard. The standard may not include all types of these NationalDifferences.DR These are National Differences based on the national regulatory requirements.D1 These are National Differences which are based on basic safety principles and requirements,eliminatio
35、n of which would compromise safety for consumers and users of products.D2 These are national differences from IEC requirements based on existing safety practices. Theserequirements reflect national safety practices, where empirical substantiation (for the IEC or nationalrequirement) is not available
36、 or the text has not been included in the IEC standard.DC These are National Differences based on the component standards and will not be deleted untila particular component standard is harmonized with the IEC component standard.DE These are National Differences based on editorial comments or correc
37、tions.Each national difference contains a description of what the national difference entails. Typically one of thefollowing words is used to explain how the text of the national difference is to be applied to the base IECtext:Addition / Add - An addition entails adding a complete new numbered claus
38、e, subclause,table, figure, or annex. Addition is not meant to include adding select words to the base IECtext.Modification / Modify - A modification is an altering of the existing base IEC text such as theaddition, replacement or deletion of certain words or the replacement of an entire clause,subc
39、lause, table, figure, or annex of the base IEC text.Deletion / Delete - A deletion entails complete deletion of an entire numbered clause,subclause, table, figure, or annex without any replacement text.SEPTEMBER 20, 2011 UL 61496-1 9UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORD
40、ISTRIBUTION WITHOUT PERMISSION FROM ULINTERNATIONAL ELECTROTECHNICAL COMMISSIONSAFETY OF MACHINERY ELECTRO-SENSITIVE PROTECTIVE EQUIPMENT Part 1: GeneralRequirements and TestsFOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all
41、 nationalelectrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on allquestions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IECpublishes International Standards
42、. Their preparation is entrusted to technical committees; any IEC National Committee interested inthe subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizationsliaising with the IEC also participate in this preparation. The IEC collabo
43、rates closely with the International Organization forStandardization (ISO) in accordance with conditions determined by agreement between the two organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensusof opinion on
44、 the relevant subjects since each technical committee has representation from all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the form of standards,technical reports or guides and they are accepted by the Nation
45、al Committees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standardstransparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standardand the corresponding nati
46、onal or regional standard shall be clearly indicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declaredto be in conformity with one of its standards.6) Attention is drawn to the possibility that some of the el
47、ements of this International Standard may be the subject of patent rights.The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61496-1 has been prepared by IEC technical committee 44: Safety ofmachinery Electrotechnical aspects, in collaborat
48、ion with CENELEC technical committee 44X: Safety ofmachinery Electrotechnical aspects.This standard has the status of a product family standard and may be used as a normative reference ina dedicated product standard for the safety of machinery.This standard has been prepared as a specification of ge
49、neral requirements for electro-sensitiveprotective equipment (ESPE) specifically related to machinery safety and has been developed to meet theneeds of manufacturers, industrial users and safety enforcement authorities.The text of this standard is based on the following documents:FDIS Report on voting44/2O6/FDIS 44/209/RVDFull information on the voting for the approval of this standard can be found in the report of votingindicated in the above table.JANUARY 29, 2002UL 61496-110UL COPYRIGHTED MATERIAL NOT AUTHORIZED FO
