EI:C0021 4 INTRODUCTION The second edition of IEC 60122-3 (1977) and its amendments 1 to 4 contained 51 enclosure types showing the dimensional and geometrical characteristi
20、cs 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, technical committee 49 has issued a questionnaire on all outlines contained in IEC 60122-3. Based on the replies received, technical comm
21、ittee 49 made a decision at the meeting held in Rotterdam in June 1996 to retain only enclosures which remained in “wide usage”. These enclosures are specified in the present standard. The following 24 enclosure types have been deleted from the second edition of IEC 60122-3 (1977) and its amendments

EI:C0021 5 QUARTZ CRYSTAL UNITS OF ASSESSED QUALITY Part 3: Standard outlines and lead connections 1 Scope This part of IEC 60122 specifies the outline dimensions and lead connections of quartz crystal units with lead enclosures. 2 Guidance for the standardization of outline drawings f
24、or frequency control and selection devices In order to achieve a uniform presentation of all outline drawings for frequency control and selection devices, the following shall be considered. 2.1 An outline drawing shall show all dimensional and geometrical characteristics of an enclosure necessary to
25、 ensure mechanical interchangeability with all other enclosures of the same outline. Enlarged detail view may be used, if necessary. 2.2 The outline drawing shall consist of three parts: 2.2.1 A drawing with dimensional symbols (capital letter) as shown in figure 1 with applicable notes, if necessar
26、y. 2.2.2 A tabular listing relating the drawing symbols to the actual dimensions. Where possible, this shall be shown on the same page as the drawing. 2.2.3 An “actual-size” sketch (scale 1:1). 2.3 The outline drawing shall be executed in the third-angle projection. 2.4 The function and identificati
27、on of the lead connections (termination) shall be determined by agreement between the supplier and user. They shall not be defined on the outline drawing. 2.5 Descriptive notes may be used at the bottom of, or adjacent to, the drawing with proper reference to the body of the drawing. 2.6 All dimensi
28、ons shall be in millimetres. 2.7 Outline dimensions A, B, C, D and E shall be listed with maximum values only. 2.8 Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum values. If applicable, nominal dimensions may be added. 2.9 The spacing of the leads (termination)
29、 symbol H shall be listed with minimum, nominal and maximum dimensions. 5 egaP 1002:322106 NE Page 5 EN 601223:2001 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 10 16:49:03 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 061-223 ?
