21、etariat of which is held by DIN. The enquiry took place at ISO/CEN level (31M/31/CDV, CEN Project = WI 00305114). However, the vote on 31M/45/FDIS took place at IEC/CLC level (agreement between ISO and IEC, see also D130/103), under the responsibility of the Technical Committee CENELEC TC 31 “Electr
22、ical apparatus for potentially explosive atmospheres”. The text of document 31M/45/FDIS, future edition 1 of ISO/IEC 80079-34:2010, prepared by Technical Committee IEC TC 31 “Equipment for explosive atmospheres”, was submitted to the IEC-CENELEC parallel vote. A draft amendment, prepared by the Tech
23、nical Committee CEN TC 305 “Electrical Potentially explosive atmospheres Explosion prevention and protection “, was submitted to the CENELEC formal vote. The combined texts were approved by CEN and CENELEC as EN ISO/IEC 80079-34 on 2011-05-25. This document supersedes EN 13980:2002. The significant
24、changes with respect to EN 13980:2002 are the following: references have been changed, especially references to CEN/CENELEC and their publications have been changed to references to international available publications; foreword and scope have been adapted to international requirements; terminology
25、has been changed and adapted to terminology being more customary in the international standardization (e. g. “notified body“ has been modified to “body responsible for verification“); information relevant to particular types of protection has been amended with Ex t - dust ignition protection by encl
26、osure, gas detectors and flame arresters; Annex B has been renamed as “Verification criteria for elements with non-measurable paths used as an integral part of a type of protection“; B.3 has been modified; information relevant to equipment and protective systems according to standards harmonized und
27、er Directive 94/9/EC are given in new Annex ZB. This standard should be read in conjunction with EN ISO 9001:2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall not be held responsible for identifying any o

36、to standards harmonized under Directive 94/9/EC ZB.1 Introduction This annex provides information on those aspects that the quality system should address with respect to particular protection laid down in harmonized standards under Directive 94/9/EC, e.g. types of protection for non-electrical equip
37、ment or components, equipment according to specific product standards and autonomous protective systems. It does not add to or otherwise change the requirements of this standard. This annex provides information how to meet the requirements of this standard, recognizing that other methods achieving t
38、he same objectives are equally acceptable; it also draws attention to aspects of requirements that may not be readily apparent to those unfamiliar with quality systems for products intended for use in potentially explosive atmospheres. The examples can be used by manufacturers to check whether the s
39、afety-relevant aspects are considered in the quality system and covered by adequate procedures (see 7.1). They can also be used for internal or external quality audits (see 8.2). NOTE The following examples do not cover all protection concepts but give some advice and will be supplemented to in the
40、next edition. ZB.2 Non-electrical equipment (EN 13463-1) ZB.2.1 General The following safety aspects as specified in the technical file should be realised by systematic production techniques and/or verifications and tests on the basis of written procedures. For dust ignition, protection the safety a
41、spects laid down in A.10 may also apply. ZB.2.2 Non-metallic parts Material characteristics; finish; surface resistance; surface area of non-conductive parts; limitation of thickness; measures for charge bonding (earthed frames).
