15、rotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields.

16、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 to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC Nat

17、ional 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 this preparation. IEC collaborates closely with the International Organization for Standardization

18、(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 international consensus of opinion on the relevant subjects since each technical committee has representatio

19、n 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 efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot

20、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 Publications transparently to the maximum extent possible in their national and regional publications.

21、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. Independent certification bodies provide conformity assessment services and, in some areas, access

22、 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) No liability shall attach to IEC or its directors, employees, servants or agents including indivi

23、dual 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 costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, t

24、his 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 application of this publication. 9) Attention is drawn to the possibility that some of the elements of t

25、his IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication o

26、f a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on

27、 an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC/TS 62700, which is a technical specification, has been prepared by technical area 14: Interfaces and methods of mea

PD IEC/TS 62700:2014TS 62700 IEC:2014(E) 5 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 100/2170/DTS 100/2231/R

32、) INTRODUCTION In consideration of global discussion on reducing e-waste and improving re-usability of power supplies, this Technical Specification addresses the common electro-mechanical characteristics for AC adapters used with a specified array of notebook computers. In the current market, hundre

33、ds of millions of notebook computers are shipped every year with AC adapters which can typically be shared between generations of OEM notebook computers. A wide range of notebook computers are designed to meet unique market requirements and specific purposes. Each AC adapter is tuned and designed to

34、 optimally satisfy the requirements and specifications of the target notebook computers. Specific combinations of OEM supplied AC adapters and notebook computers are tested and certified as a system in compliance with existing regulations and standards. Failing combinations are not shipped by the OE

35、M to the consumer. This approach promotes consumer satisfaction, safety, and product reliability, while reducing the encroachment of poorly designed or manufactured aftermarket substitutes which may affect the operation of the notebook computer in compliance with regulatory requirements. Additionall

36、y, arbitrary combinations of AC adapters and notebook computers have been known to present functional and regulatory safety and EMC compliance issues for the notebook computer. These risks should be considered in any development or adoption of specifications for common AC adapters. The objective of

37、a common DC power supply is to support global interoperability of adapters for a specific range of notebook computers. This Technical Specification describes design considerations for the common adapters and identifies technical areas that require further development for interoperability with existi

38、ng notebook computer technologies. The open technical and regulatory compliance issues identified within this Technical Specification which affect both AC adapters and the host notebook computers should be resolved before this specification can be considered as a normative within other standards or

39、regulatory policies and before IEC standardization of the subject matter can be completed. This Technical Specification also identifies important considerations required to maintain the high standard of safety, compliance and performance expected by users of notebook computers and global regulatory

40、agencies. The development of this Technical Specification is described in Annex A. Annexes C, D and E describe additional important areas which are required to be resolved in further standardization work. The objective for future IEC standardization work will be to complete the development of the te

41、chnical specifications which incorporates considerations for consumer safety, product reliability, system performance, regulatory compliance and technical innovations. PD IEC/TS 62700:2014TS 62700 IEC:2014(E) 7 DC POWER SUPPLY FOR NOTEBOOK COMPUTERS 1 Scope This Technical Specification states the mi

42、nimum requirements for DC power supply for notebook computers. Specifically, it gives an electrical specification (performance characteristics), an ID pin method, a connector for DC power output. The no-load power and power efficiency are outside the scope of this Technical Specification. Note that

43、safety requirements are covered by IEC 60950-1 and EMC requirements are covered by CISPR 22 and CISPR 24. CISPR 32 may be used in place of CISPR 22 for this purpose. These requirements are neither re-stated nor challenged by this Technical Specification but the designer should give due consideration

44、 to the performance of the power supply when used with a compatible notebook computer. NOTE Applications for use in aerospace, military, medical, or smart grid are not addressed in this Technical Specification. 2 Normative references The following documents, in whole or in part, are normatively refe
