AMENDMENT 1
FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental,
in liaison with ISO and IEC, also take part in the work.
2) The formal decisions or agreements of IEC and ISO 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 and ISO National bodies.
3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and
ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC and ISO documents is accurate, IEC and ISO 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 and ISO National bodies undertake to apply IEC and ISO
documents transparently to the maximum extent possible in their national and regional publications. Any
divergence between any IEC and ISO document and the corresponding national or regional publication shall be
clearly indicated in the latter.
5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO are not
responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this document.
7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual
experts and members of its technical committees and IEC and ISO National bodies 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 ISO/IEC document or any
other IEC and ISO documents.
8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is
indispensable for the correct application of this document.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC document may be the subject of
patent rights. IEC and ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO/IEC 11801-3 has been prepared by subcommittee SC 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
The text of this Amendment is based on the following documents:

INTRODUCTION
Add the following NOTE below the Figure 1 title:
NOTE Telecommunications infrastructure affects raw material consumption. The infrastructure design and
installation methods also influence product life and sustainability of electronic equipment life cycling. These aspects
of telecommunications infrastructure impact our environment. Since building life cycles are typically planned for
decades, technological electronic equipment upgrades are necessary. The telecommunications infrastructure design
and installation process magnifies the need for sustainable infrastructures with respect to building life, electronic
equipment life cycling and considerations of effects on environmental waste. Telecommunications designers are
encouraged to research local building practices for a sustainable environment and conservation of fossil fuels as
part of the design process.
