3、8. It is identical with IEC60679-5-1:1998. It supersedes BS EN169201:1996 which will be withdrawn on 2001-05-01. The UK participation in its preparation was entrusted to Technical Committee EPL/49, Piezoelectric devices for frequency control and selection, which has the responsibility to: aid enquir
4、ers 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 organizations rep
5、resented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 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 system to the other
6、, 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 Standards whic
7、h 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 purport to include al
8、l 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 cover, pagesi and

21、 specification and contains requirements for style, layout and minimum content of detail specifications. In the preparation of detail specifications the content of clause 2 of IEC60679-5 shall be taken into account. This specification may be inappropriate for small batch production of quartz crystal
22、 controlled oscillators in which case the capability approval approach is recommended. (See IEC 60679-4.) Identification of the detail specification (DS) and of the component The first page of the DS should have the layout recommended below. The numbers between the square brackets on the front page
23、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 DS is published and, if applicable, that of the organization from which the DS is available. 2 The IECQ number allotted to the DS. 3 The
24、 number and issue number of the IEC generic or sectional specification as relevant as well as the national reference if different. 4 If different from the IECQ number, the national number of the DS, date of issue and any further information required by the national system, together with any amendmen
25、t 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 construction (where applicable) (for example, resistance welded, cold welded). For 5 and 6 the text to be given in the DS should be
26、suitable for entry in IECQC001005 and IECQC001004. 7 An outline drawing with the main dimensions which are of importance for interchangeability as demanded in IEC60679-3 and/or reference to the appropriate national or international document for outlines. Alternatively, this drawing may be given in a
27、n annex to the DS, but 7 should always contain an illustration of the general outer appearance of the component. 8 The level(s) of quality assessment covered by the DS. 9 Reference data giving information on the most important properties of the component which allow comparison between the various co
