14、EC 2016 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ _ _ _ _ _ _ _ _ _ _ _ PRINTED ELECTRONICS Part 202: Materials Conductive inkFOREW ORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Na
15、tional Committees). The object of IEC is to promote international co-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, Pub
16、licly Available Specifications (PAS) and Guides (hereafter referred 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-gov
17、ernmental organizations liaising with the IEC also participate in this 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
18、 on technical matters express, as nearly as possible, an international 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 accep
19、ted by IEC National Committees in that sense. W hile all reasonable efforts 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 internatio
20、nal uniformity, IEC National Committees undertake to apply IEC Publications 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 la
21、tter. 5) IEC itself does not provide any attestation of conformity. Independent 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 sho
22、uld 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 individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other dam
23、age 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, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of
24、 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 this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent righ

BS IEC 62899-202:2016 6 IEC 62899-202:2016 IEC 2016 INTRODUCTION The IEC 62899-20x series relates mainly to evaluation methods for materials of printed electronics. The seri
29、es also include storage methods, packaging and marking, and transportation conditions. The IEC 62899-20x series is divided into parts for each material. Each part is prepared as a generic specification containing fundamental information for the area of printed electronics. The IEC 62899-20x series c
30、onsists of the following parts: Part 201: Materials Substrates Part 202: Materials Conductive ink Part 203: Materials Semiconductor ink1(Subsequent parts will be prepared for other materials.) Furthermore, sectional specifications, blank detail specifications, and detail specifications of each mater
31、ial will follow these parts. This part of IEC 62899 is prepared for conductive materials used in printed electronics and contains the test conditions, the evaluation methods and the storage conditions. _ _ _ _ _ _ _ _ _ _ _ _ _ 1Under consideration.
