20、l 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. To this en
21、d 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 National Comm
22、ittee 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 (ISO) in ac
23、cordance 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 representation from all
24、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 be held res
25、ponsible 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. Any diverge
26、nce 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 to IEC mar
27、ks 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 individual expert
28、s 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, this IEC Pub
29、lication 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 this IEC Pub
30、lication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60122-3 has been prepared by IEC Technical Committee 49: Piezoelectric, dielectric and electrostatic devices and associated materials for frequenc
31、y control, selection and detection. This fourth edition cancels and replaces the third edition published in 2001. This fourth edition constitutes a technical revision. The main changes with respect to the previous edition are as follows: 12 of the 48 enclosure types contained in the previous edition

A list of all parts of IEC 60122 series, published under the general title, Quartz crystal units of assessed quality, can be found on the IEC website.

At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60122-3 IEC:2010 5 INTRODUCTION The thir
35、d edition of IEC 60122-3 (2004) contained 48 enclosure types showing the dimensional and geometrical characteristics of these enclosures. Since its release, due to progress in technology, many of the enclosures given in the standard have become obsolete. Bearing this in mind, the following 12 enclos
36、ure types have been deleted from the third edition of lEC 60122-3. AA, AB, BC, BC/1, BF, BF/1, CX, CY, CY/1, CZ, DA, DC. Therefore, this new version (the fourth edition) contains the following 36 enclosure types ; CK, CM, CN, CP, DK, DL, DP, EH, DQ, DR, DZ, DV, DW, ED, EB, EJ, EK, CU 01A, CU 01B, CU

38、ce for the standardization of outline drawings for frequency control and selection devices 2.1 General In order to achieve a uniform presentation of all outline drawings for frequency control and selection devices the following guide shall be considered: 2.2 An outline drawing shall show all dimensi
39、onal and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the same outline. Enlarged detailed view may be used, if necessary. 2.3 The outline drawing shall consist of three parts: 2.3.1 A drawing with dimensional symbols (capi
40、tal letter) as shown in Figure 1 below with applicable notes, if necessary. 2.3.2 A tabular listing relating to the drawing symbols to the actual dimensions. Where possible this shall be shown on the same page as the drawing. 2.3.3 An “actual-size“ sketch (scale 1:1). 2.4 The outline drawing shall b
41、e executed in the third angle projection. 2.5 The function and identification of the lead connections (termination) shall be determined by agreement between the supplier and user. They shall not be defined on the outline drawing. 2.6 Descriptive notes may be used at the bottom of/ or adjacent to, th
42、e drawing with proper reference to the body of the drawing. 2.7 All dimensions shall be in millimeters. 2.8 Outline dimensions A, B, C, D and E shall be listed with maximum values only. 2.9 Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum values. If applicable,
43、nominal dimensions may be added. 2.10 The spacing of the leads (termination) symbol H shall be listed with minimum, nominal and maximum dimensions. 60122-3 IEC:2010 7 NOTE 1 In this sentence, a comment related to K or to the number X should be notified. NOTE 2 In this sentence, a comment related to
44、U and W or to the number X should be notified Figure 1 Guidance for outline drawings Scale 2 :1 Sheet - number 2.11 If leads (terminations) are provided with an undercut dimensions U and W shall be listed with minimum dimensions only. 3 Dimensions of quartz crystal unit enclosures The dimensions in
