FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61300-3-36 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:
FDIS Report on voting
86B/1282/FDIS 86B/1307/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged
until 2003. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

1 Scope
This International Standard describes the measurement methods of the inside diameter of fibre
optic connector ferrules.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO
and IEC maintain registers of currently valid International Standards.

3 Measurement methods for the inside diameter of fibre optic connector ferrules
3.1 Purpose
The purpose of this procedure is to inspect and measure the inside diameter of the precision
hole of fibre optic connector ferrules. The precision hole aligns and positions the optical fibre
inside the ferrule. The procedure described here uses the "GO" and "NO-GO" gauging
technique.
3.2 General description
The most commonly used inspection method for the inside diameter is the GO and NO-GO pin
gauging technique.
Due to the very small inside diameters of the connector ferrules for commonly used single
mode and multimode ferrules, accurate direct measurement is difficult to achieve. One
technique is the direct measurement of the inside diameter of a ferrule precision alignment
hole. This can be carried out either by projecting the ferrule hole using a projection optical
microscope or by using an imaging and digitizing system to measure the bore diameter. These
techniques tend to suffer from inaccuracy in determining the inside edges of a precision hole.
Thus, the use of "pin gauges" became the most common method for determining the inside
diameter of a ferrule manufactured to specified dimensional limits.

3.3 Inspection method: pin gauging technique
The pin gauges shall be made from hard-wearing material, such as tungsten carbide, ruby or
hard ceramic and shall be rigid.
