2、, having been prepared under the direction of the Electrotechnical Sector Board, was published under the authority of the Standards Board and comes into effect on 15 June 1998 BSI 04-1999 ISBN 0 580 29932 5 National foreword This British Standard is the English language version of EN60679-4-1:1998.
3、It is identical with IEC60679-4-1:1998. It supersedes BSEN169101:1995 which will be withdrawn in due course (see note on page2). The UK participation in its preparation was entrusted to Technical Committee EPL/49, Piezoelectric devices for frequency control and selection, which has the responsibilit
4、y to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of o
5、rganizations represented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering syst
6、em to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British
7、 Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purpor
8、t to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cov

For custom-b
22、uilt quartz crystal controlled oscillators 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 be followed whenever possible. Identification of the detail specification
23、 and of the component The numbers between square brackets on the front page 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 applicable, the or
24、ganization from whom the detail specification is available. 2 The IECQ number allotted to the detail specification. 3 The number and issue number of the IEC generic or sectional specification, as relevant; also national reference if different. 4 If different from the IEC number, the national number
25、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 controlled oscillator, or range of oscillators (for example, SPXO and output frequency). 6 Information on typical c
26、onstruction, where applicable (for example, resistance-welded or cold-welded). For 5 and 6 the text to be given in the detail specification should be suitable for an entry in IECQC001005 and IECQC001004. 7 An outline drawing with the main dimensions which are of importance for interchangeability, as
27、 demanded in IEC60679-3, and/or reference to the appropriate national or international document for outlines. Alternatively, this drawing may be given in an annex to the detail specification.

36、rification of the detail specification. 7 Inspection requirements Subclause numbers of tests and performance requirements refer to IEC60679-1. The ILs and AQLs given in Table 1 are the minimum quality levels required and are selected from IEC60410. In this table D = destructive; ND = non-destructive
37、, IL = inspection level; AQL = acceptance quality level. The manufacturer and his customer shall ensure that any quality aspects of the quartz crystal controlled oscillator to be supplied, that are not covered by the maintenance of the capability approval programme, are included in the detail specif
