22、N ELECTROTECHNICAL PRODUCTS Part 1: Introduction and overview FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international c
23、o-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred
24、 to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in th
25、is preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internation
26、al consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable e
27、fforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Public
28、ations transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. I
29、ndependent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7)
30、No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for cost
31、s (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct applica
32、tion of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62321-1 has been prepared by IEC techn
33、ical committee 111: Environmental standardization for electrical and electronic products and systems. The first edition of IEC 62321:2008 was a stand-alone standard that included an introduction, an overview of test methods, a mechanical sample preparation as well as various test method clauses. Thi
34、s first edition of IEC 62321-1 is a partial replacement of IEC 62321, forming a structural revision and replacing Clauses 1 to 4. Future parts in the IEC 62321 series will gradually replace the corresponding clauses from IEC 62321:2008. Until such time as all parts are published, however, IEC 62321:
35、2008 remains valid for those clauses not yet re-published as a separate part. 4 62321-1 IEC:2013 The text of this standard is based on the following documents: FDIS Report on voting 111/295/FDIS 111/306/RVD Full information on the voting for the approval of this standard can be found in the report o
36、n voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62321 series can be found on the IEC website under the general title: Determination of certain substances in electrotechnical products. The commi
37、ttee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised editi
38、on, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 62321-1 IEC:2013 5 INTRODUCTIO
39、N The widespread use of electrotechnical products has drawn increased attention to their impact on the environment. In many countries this has resulted in the adoption of regulations affecting wastes, substances and energy use of electrotechnical products. The use of certain substances (e.g. lead (P
40、b), cadmium (Cd) and polybrominated diphenyl ethers (PBDEs) in electrotechnical products, is a source of concern in current and proposed regional legislation. The purpose of the IEC 62321 series is therefore to provide test methods that will allow the electrotechnical industry to determine the level
41、s of certain substances of concern in electrotechnical products on a consistent global basis. The first edition of IEC 62321:2008 was a single stand-alone standard that included an introduction, an overview of test methods, a mechanical sample preparation as well as various test method clauses. The
42、structure of the new multi-part IEC 62321 series comprises: Determination of certain substances in electrotechnical products Part 1: Introduction and overview. Determination of certain substances in electrotechnical products Part 2: Disassembly, disjointment and mechanical sample preparation. The re
43、maining parts specify screening and verification test methods for the determination of certain substances, each part representing a given substance. WARNING Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all of
44、the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 6 62321-1 IEC:2013 DETERMINATION OF CERTAIN SUBSTANCES IN ELECTROTECHNICAL PRODUCTS Part 1
45、 Introduction and overview 1 Scope This part of IEC 62321 refers to the sample as the object to be processed and measured. The nature of the sample and the manner in which it is acquired is defined by the entity carrying out the tests and not by this standard. It is noted that the selection of the
46、sample may affect the interpretation of the test results. While this standard provides guidance on the disassembly procedure employed for obtaining a sample, it does not determine or specify: the level of the disassembly procedure required for obtaining a sample; the definition of a “unit” or “homog
47、enous material” as the sample; conformity assessment procedures. NOTE Further guidance on assessment procedures may be found in IEC/TR 62476 2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
48、For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
