INTRODUCTION
Add, at the end of the existing introductions the following text:
INTRODUCTION to Amendment 2
Amendment 2 of ISO/IEC 11801:2002 provides balanced cabling models, requirements and
normative references for Category 6 and Category 7 components, requirements for Class
A A
E and Class F links, together with amendments to the requirements for optical fibre cabling.
A A
Global change:
Replace, throughout ISO/IEC 11801:2002 and Amendment 1:2008 “optical fibre channel” by
“optical fibre cabling channel”.
2 Normative references
Replace the entire existing Clause 2 of both ISO/IEC 11801:2002, as well Amendment 1:2008,
by the following:
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.

The provisions of the referenced specifications other than ISO/IEC, IEC, ISO and ITU
documents, as identified in this clause, are valid within the context of this International
Standard. The reference to such a specification within this International Standard does not
give it any further status within ISO or IEC. In particular, it does not give the referenced
specification the status of an International Standard.

meeting the requirements of Annex A;

Delete, in Amendment 1:2008, the following text and referenced footnote:
Until amendment 2 of ISO/IEC 11801:2002 has been published:

be clearly documented within a quality plan as described in ISO/IEC 14763-2.
Installation and administration of cabling in accordance with this International Standard shall
be undertaken in accordance with ISO/IEC 14763-2.
This International Standard does not specify which tests and sampling levels should be
adopted. The test parameters to be measured and the sampling levels to be applied for a
particular installation shall be defined in the installation specification and quality plans for that
installation prepared in accordance with ISO/IEC 14763-2.
