1、BRITISH STANDARD BS EN 60204-1:1998 IEC 60204-1: 1997 Safety of machinery Electrical equipment of machines Part 1: General requirements The European Standard EN60204-1:1997 has the status of a British Standard ICS13.110;29.020;31.020BSEN60204-1:1998 This British Standard, having been prepared under

2、the directionof the Electrotechnical Sector Board, was published underthe authority of the Standards Board and comes intoeffect on 15November1998 BSI 05-1999 ISBN 0 580 30668 2 National foreword This British Standard is the English language version of EN60204-1:1997. Itis identical with IEC60204-1:1

3、997. This British Standard supersedes BSEN60204-1:1993 which remains current for use as a reference standard with BS EN60204-31 1) . The UK participation in its preparation was entrusted to Technical Committee GEL/44, Safety of machinery electrotechnical aspects, which has the responsibility to: aid

4、 enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizati

5、ons represented on this committee can be obtained on request to its secretary. From 1January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the o

6、ther, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards

7、which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue.

Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an insi

17、1999 2 Foreword The text of document44/205/FDIS, future edition4 of IEC60204-1, prepared by IEC TC44, Safety of machinery: Electrotechnical aspects, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN60204-1 on1997-10-01. This standard has been prepared under a mandate g

18、iven to CEN/CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of the following EC Directives: Low Voltage Directive(73/23/EEC); Machinery Directive(89/392/EEC). This European Standard supersedes EN60204-1:1992 and its corrigendum December199

19、3. Significant technical differences have resulted from the amendments to the Machinery Safety Directive in 1991 covering mobility and lifting, and in 1993 covering safety components. The following dates were fixed: Annexes designated “normative” are part of the body of the standard. Annexes designa

20、ted “informative” are given for information only. In this standard, Annex ZA is normative and Annex A, Annex B, Annex C, Annex D and Annex E are informative. Annex ZA has been added by CENELEC. This standard has the status of a horizontal standard (type B in CEN) and may be used as a reference stand

21、ard by technical committees in CEN and in CENELEC in the preparation of product family standards or dedicated product standards (type C in CEN as defined in EN414:1992, 3.1) for machines. The requirements of this standard can also be applied by the supplier of a machine for which no product family o

22、r dedicated product standard exists. Where a product family or dedicated product standard exists, its requirements take precedence over the requirements of this standard. EN60204-1 gives a large number of general requirements that may or may not be applicable to the electrical equipment of a particu

23、lar machine. A simple reference without any qualification to the complete standard EN60204-1 is therefore not sufficient. Choices need to be made to cover all requirements of EN60204-1. A technical committee preparing a product family or a dedicated product standard (type C in CEN) and the supplier

24、of a machine for which no product family or dedicated product standard exists, should use this standard; a) by reference; and b) by selection of the most appropriate option(s) from the requirements given in the relevant clauses; and c) by modification of certain clauses as necessary where the partic

25、ular requirements for the equipment of the machine are adequately covered by other relevant standards, providing the options selected and the modifications made do not adversely affect the level of protection required for that machine according to the risk assessment. When applying the three princip

26、lesa),b) andc) listed above, it is recommended that; reference be made to the relevant clauses and subclauses of this standard 1) that are complied with, indicating where relevant the applicable option; 2) that have been modified or extended for the specific machine or equipment requirements; and re

27、ference be made directly to the relevant standard, for the requirements for the electrical equipment that are adequateley covered by that standard. In all cases expertise is essential to be able to: perform the necessary risk assessment of the machine; read and understand all of the requirements of

29、 for use with EN60204-3-1:1990.EN60204-1:1997 BSI 05-1999 3 choose the applicable requirements from EN60204-1 where alternatives are given; identify alternative or additional particular requirements that differ from or are not included in the requirements of EN60204-1, and that are determined by the

30、 machine and its use; and specify precisely those particular requirements. Figure 2 of EN60204-1 is a block diagram of a typical machine and can be used as the starting point of this task. It indicates the clauses and subclauses dealing with particular requirements/equipment. However EN60204-1 is a

31、complex document and the use of the following table will give help in the finding of a required area in this standard and gives reference to other relevant standards.
