For a cabling installation to conform to this document the following applies.
a) The configuration and structure shall conform to the requirements outlined in Clause 5.
b) Channels shall meet the requirements specified in Clause 6 when subjected to environment conditions, local to the channels (see NOTE 2 below), as defined by the applicable environmental Class(es) of Clause 6. This shall be achieved by one of the following:
1) a channel design and implementation ensuring that the prescribed channel performance of Clause 6 is met;
2) attachment of appropriate components to a permanent link design meeting the prescribed performance class of Clause 7. Channel performance shall be ensured where a channel is created by adding more than one cord to either end of a link meeting the requirements of Clause 7;
3) for E1 environments, using the reference implementations of Clause 8 and compatible cabling components conforming to the requirements of Clauses 9, 10 and 11 based upon a statistical approach of performance modelling.
NOTE 1 This approach is not applicable to Class BCT .B cabling.
c) The interfaces to the cabling at the TO and BO shall conform to the requirements of Clause 10 with respect to mating interfaces and performance when subjected to environment conditions, local to the connecting hardware (see NOTE 2 below), as defined by the applicable environmental Class(es) of Clause 6.
d) Connecting hardware at other places in the cabling structure shall meet the performance requirements specified in Clause 10 when subjected to environment conditions, local to the connecting hardware (see NOTE 2 below), as defined by the applicable environmental Class(es) of Clause 6.
e) The requirements of ISO/IEC 14763-2 and ISO/IEC 30129 shall be met.
This document does not specify which tests and sampling levels should be adopted. Test methods to assess conformance with the channel and link requirements of Clause 6 and Clause 7,respectively, are specified in ISO/IEC 11801-1. The test parameters to be measured, the sampling levels and the treatment of measured results to be applied for particular installation shall be defined in the installation specification and quality plan for that installation prepared in accordance with ISO/IEC 14763-2.
In the absence of the channel, the conformance of the link shall be used to verify conformance with this document.ISO IEC 11801-4 pdf download.
