MECHANICAL SPLICES AND FUSION SPLICE PROTECTORS
FOR OPTICAL FIBRES AND CABLES –
Part 1: Generic specification
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 61073-1 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 1994, and constitutes a
technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
86B/1243/FDIS 86B/1278/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 QC number that appears on the front cover of this publication is the specification number
in the IEC Quality Assessment System for Electronic Components (IECQ).
The committee has decided that this publication remains valid until 2004. At this date, in
accordance with the committee's decision, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

2.1.6 Assessment level
Assessment level defines the inspection levels and the acceptable quality level (AQL) of
groups A and B and the periodicity of inspection of groups C and D. Detail specifications shall
specify one or more assessment levels, each of which shall be designated by a capital letter.
The following are preferred levels.
– Assessment level A
• Group A inspection: inspection level 11, AQL = 4 %
• Group B inspection: inspection level 11, AQL = 4 %
• Group C inspection: 24-month periods
• Group D inspection: 48-month periods
– Assessment level B
• Group A inspection: inspection level 11, AQL = 1 %
• Group B inspection: inspection level 11, AQL = 1 %
• Group C inspection: 18-month periods
• Group D inspection: 36-month periods
– Assessment level C

• Group C inspection: 12-month periods
• Group D inspection: 24-month periods
When an assessment level other than one of the above is used, it shall be designated with the
capital letter X.
2.1.7 Normative reference extensions
Normative reference extensions are utilised to identify integration of independent standards
specifications or other reference documents into blank detail specifications.
Unless specified exception is noted, additional requirements imposed by an extension are
mandatory. Usage is primarily intended to merge associated components to form hybrid
devices, or can involve integrated functional application requirements that are dependent on
technical expertise other than fibre optics.
Published reference documents produced by ITU consistent with the scope statements of the
relevant IEC specification series may be utilised as extensions. Published documents produced
by other regional standardisation bodies such as TIA, ETSI, JIS, etc., may be referenced in an
informative annex attached to the generic specification.
Some optical fibre splice configurations require special qualification provisions that are not
necessary to impose universally. These accommodate individual component design
configurations, specialised field tooling, or specific application processes. In such cases
requirements may be necessary to assure repeatable performance or adequate safety, and
provide additional guidance for complete product specification. These extensions are
---------------------- Page: 16 ----------------------
61073-1 © IEC:1999 – 23 –
mandatory whenever utilised to prepare, assemble or install an optical fibre splice, either for
field application usage or preparation of qualification test specimens. The relevant specification
shall clarify all stipulations. However, design- and style-dependent extensions shall not be
imposed universally.
In the event of conflicting requirements, precedence shall be given, in descending order, as
follows: generic over mandatory extension, over blank detail, over detail, over application
specific extension.
Examples of requirements in normative extensions include the following:
• some commercial or residential building applications may require direct refe
