27、The International Electrotechnical 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
28、and electronic fields. To this end 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
29、committees; any IEC National Committee 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 Organizati
30、on for Standardization (ISO) in accordance 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 comm
31、ittee has representation from all 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 i
32、s accurate, IEC cannot be held responsible 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
33、regional publications. Any divergence 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
34、, in some areas, access to IEC marks 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
35、agents including individual experts 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
36、of, or reliance upon, this IEC Publication 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 so
37、me of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61300-3-25 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of
38、 IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2013 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) deletion of method C due to potenti
39、al damage of ferrule end face by the spindle. Method C is the ferrule bore reference method for bare ferrules according to IEC 61300-3-25:2013; b) separation of original method A into method A-1 and method A-2 relating to the two different types of ferrule (with/without fibre fitted); c) integration
40、 of the content of Annexes A and B into the test procedure. 4 IEC 61300-3-25:2016 IEC 2016 The text of this standard is based on the following documents: CDV Report on voting 86B/3900/CDV 86B/3956A/RVC Full information on the voting for the approval of this document can be found in the report on vot
41、ing indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61300 series, published under the general title, Fibre optic interconnecting devices and passive components Basic test and measurement procedures, can be
42、 found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, r
43、eplaced by a revised edition, or amended. IEC 61300-3-25:2016 IEC 2016 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-25: Examinations and measurements Concentricity of non-angled ferrules and non-angled ferrules with fibre installed 1 Scope
44、 This part of IEC 61300 describes the procedure to determine the concentricity of the axis of the bore in a non-angled ferrule with the axis of the ferrule, and in the case of non-angled ferrules with fibre installed, to determine the concentricity of the axis of the fibre core with the axis of the
45、ferrule. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (
46、including any amendments) applies. There are no normative references in this document. 3 General description 3.1 General This procedure describes the measurement of concentricity of ferrules and ferrules with assembled fibres. Concentricity is defined as twice the distance between the axis of the fe
47、rrule and the axis of the inner diameter of the ferrule (ferrule bore), or in the case of ferrules with fibre installed, twice the distance between the axis of the ferrule and the axis of the core of the installed fibre (see Figure 1). When concentricity measurements are made on a ferrule with fibre
48、 installed the results will be affected by the geometry of the fibre, and by the fit of the fibre in the ferrule inner diameter. Imperfections of the cylindricity and circularity of the outside diameter of the ferrule will influence the measurement results. Figure 1 Definition of concentricity Two m
49、ethods of concentricity measurement are described in 3.2 and 3.3.
