18、ronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The compo
19、nents produced under the System are thereby acceptable in all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for QUARTZ CRYST
20、AL UNITS. It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this document the member countries of the CECC are, Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerla
21、nd and the UnitedKingdom, and copies of it can be obtained from the addressees shown on the blue fly sheet. Preface This blank detail specification was prepared by CECC Working Group17: Piezoelectric devices for frequency control and selection. It is based, wherever possible, on the Publications of
22、the International Electrotechnical Commission and in particular on IEC Publication122-1: Quartz crystal units for frequency control and selection Part1:Standard values and test conditions. The text of this blank detail specification was circulated to the CECC for voting in the documents listed below
23、 and was ratified by the President of the CECC for publication as a CECC Specification. NOTEThis specification is published initially in French and English. The German text will follow as soon as it has been prepared. Contents Page Foreword 2 1 Ratings 4 2 Characteristics 4 3 Related documents 5 4 M

The front page layout shown on page4 is appl
26、icable to detail specifications for standard catalogue items only. For custom-built quartz crystal units where the detail specification is not intended for publication, a suggested layout for the front page is given in Annex A. This is not mandatory, but it is recommended that the layout should be f
27、ollowed whenever possible. Key for page 4 The numbers between the square brackets on page4 correspond to the following information which should be given in the appropriate boxes. 1 The name of the National Standards Organization under whose authority the detail specification is published and, if app
28、licable, the organization from whom the detail specification is available. 2 The CECC Symbol and the number allotted to the detail specification by the CECC General Secretariat. 3 The number and issue number of the CECC generic or sectional specification as relevant; also national reference if diffe
29、rent. 4 If different from the CECC number, the national number of the detail specification, date of issue and any further information required by the national system, together with any amendment numbers. 5 A brief description of the quartz crystal unit or range of quartz crystal units. (For example
30、frequency, order, cut, mode) 6 Information on typical construction (where applicable). (For example resistance welded, cold welded). For 5 and 6 the text to be given in the detail specification should be suitable for an entry in CECC00200 (QPL) and CECC00300 (Library List). 7 An outline drawing with
31、 main dimensions which are of importance for interchangeability and/or reference to the appropriate national or international document for outlines.
