INTRODUCTION
Add, after Figure 1, the following new text:
IEC Guide 109 advocates the need to minimise the impact of a product on the natural
environment throughout the product life cycle.
It is understood that some of the materials permitted in this standard may have a negative
environmental impact.
As technological advances lead to acceptable alternatives for these materials, they will be
eliminated from the standard.

SECTION 4: PRACTICAL GUIDANCE
Replace the existing clauses of section 4 by the following new clauses:
14 General
This practical guidance is applicable for non-accessible ID connections made with insulated
stranded or solid copper conductors and is for information only. These connections shall be
produced by special wire insertion tools (fully automatic, semi-automatic or hand-operated
insertion tools). Conductors made of other materials (aluminium, etc.) often require special
actions regarding the ID-terminations and the insertion tools, which should be agreed upon by
the manufacturer.
14.1 Advantages of ID connections
An ID connection made by the ID technique is usually a permanent electrical connection
between one conductor and an ID termination of any shape. There are also terminations that
allow more than one wire insertion in the same connection slot. Good electrical connections
are achieved by exactly matching insertion tools, ID slots and conductor cross-sections and
by the maintenance of a force on the solid wire or on the conductor strands.
Advantages:
– no wire stripping;
– low insertion force into slot, which allows simultaneous insertion of wires;
– usable with ribbon cables and discrete wires;
– efficient processing of contacts at each production level;
– processing by fully automatic or semi-automatic wire insertion tool machines or with hand-
operated tools;
– no degradation of the spring characteristic of ID termination or the female or male contacts
of the connector by the soldering temperature;
– preservation of conductor flexibility behind the ID connection;
– to eliminate effects such as no cold-soldered joints, no health risk through heavy metal
and flux steam and no burnt, discoloured and overheated conductor insulations;
– good connections with reproducible electrical and mechanical values;
– easy production control.
14.2 Current-carrying capacity
The current-carrying capacity of a non-accessible ID connection is determined by the lower
value given either by the current-carrying capacity of the connected wire or by the current-
carrying capacity of the ID termination.
Consideration should be given to the fact that the current-carrying capacity can be influenced
by the
– contact material;
– surface finish of the contact;
– cross-section of the conductor;
– surface finish of the conductor;
– pitch (spacing) of a multipole connector;
– number of connected wires in a multipole connector;
– ambient temperature.

15 Tool information
15.1 Wire insertion tool
Generally, a wire insertion tool is required to establish a non-accessible ID connection. If a
tool is used, it should be able to act upon the wire on both sides of the connection slot, i.e. on
both sides of the ID termination, during the wire-insertion process. The tool should also
provide for a correct location of the wire in the connection slot, for example, for the correct
depth of the wire in the slot. This may be ensured by arrangement of a depth stop. The
