4、ELECTROTECHNICAL COMMISSION_SYMBOL AND LABELS FOR MOISTURE-SENSITIVE DEVICESFOREWORDA PAS is a technical specification not fulfilling the requirements for a standard,but made available to thepublic and established in an organization operating under given procedures.IEC-PAS 62168 was submitted by JED
5、EC and has been processed by IEC technical committee 47:Semiconductordevices.The text of this PAS is based on thefollowing document:This PAS was approved forpublication by the P-members of thecommittee concerned as indicated inthe following document:Draft PASReport on voting47/1468/PAS47/1501/RVDFol
6、lowing publication of this PAS,the technical committee or subcommittee concerned will investigate thepossibility of transforming the PAS into an International Standard.An IEC-PAS licence of copyright and assignment of copyright has been signed by the IEC and JEDEC and isrecorded at the Central Offic
7、e.1)The IEC(International Electrotechnical Commission)is a worldwide organization for standardization comprising allnational electrotechnical committees(IEC National Committees).The object of the IEC is to promote international co-operation on all questions concerning standardization in the electric
8、al and electronic fields.To this end and in additionto other activities,the IEC publishes International Standards.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
9、 and non-governmental organizations liaising with the IEC also participate in this preparation.The IECcollaborates closely with the International Organization for Standardization(ISO)in accordance with conditionsdetermined by agreement between the two organizations.2)The formal decisions or agreemen
10、ts of the IEC on technical matters express,as nearly as possible,an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from all interestedNational Committees.3)The documents produced have the form of recommendations for international use and
11、are published in the form ofstandards,technical specifications,technical reports or guides and they are accepted by the National Committees inthat sense.4)In order to promote international unification,IEC National Committees undertake to apply IEC International Standardstransparently to the maximum
12、extent possible in their national and regional standards.Any divergence between theIEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequi
13、pment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this PAS may be the subject of patent rights.TheIEC shall not be held responsible for identifying any or all such patent rights.LICENSED TO MECON Limited.-RANCHI/BANGALOR
