FOREWORD
1) 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 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 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 Organization 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 committee 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 is 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 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, 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 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 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 some 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 61300-2-24 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition replaces the first edition published in 1999. This second edition
constitutes a technical revision. Specific technical changes involve the addition of a
dimension example of the reference gauge and the plate for the ceramic sleeve and a
commonly used ceramic alignment sleeve for the 1,25 mm ceramic sleeve.

Part 2-24: Tests –
Screen testing of ceramic alignment
split sleeve by stress application

1 Scope
The purpose of this part of IEC 61300 is to identify weaknesses in a ceramic alignment split
sleeve which could lead to early failure of the component.
2 General description
Ceramic alignment sleeves are important components often used in the adaptor of plug-
adaptor-plug optical connector sets. By using the method described, the component is
subjected to a proof stress greater than would be experienced under normal service
conditions. This enables weak products to be screened out.
3 Apparatus
The apparatus and arrangement necessary to perform this screening procedure are shown in
Figure 1. The material needed consists of the following:
a) a reference gauge made of ceramic with a sleeve-holding section, a tapered section and a
stress-applying section. The diameter of each section is dependent on the dimensions of
the product being screened. The length of the sleeve-holding section and the stress-
applying section should be greater than the component being tested;
b) plates A and B, each having a clearance hole in the centre to allow the plate to move a
sample of a ceramic alignment split sleeve on the reference gauge.

4 Procedure
This test should be carried out under a 23 °C ± 2 °C environmental temperature condition.
The procedure is as follows.
a) Insert plate A into the reference gauge and set it at the fixed end of the reference gauge.
b) Moisten the inside surface of a ceramic split sleeve sample with distilled water (for
example using a cotton bud). Only touch the sleeve with suitable tools.
c) The sample sleeve is inserted onto the sleeve-holding part and set just in front of the
tapered part of the reference gauge.
d) Insert plate B into the left-hand side of the sample sleeve and move the sample sleeve
onto the stress-applying part until the sample sleeve touches plate A (within approximately
1 s).
e) The sample sleeve should be held for 3 s under the stressed stat
