This part of IEC 61935 specifies reference measurement procedures for cabling parameters
and the requirements for field tester accuracy to measure cabling parameters identified in
ISO/IEC 11801. References in this standard to ISO/IEC 11801 mean ISO/IEC 11801 or
equivalent cabling standards.
This International Standard applies when the cable assemblies are constructed of cables
complying with the IEC 61156 family of standards, and connecting hardware as specified in
the IEC 60603-7 family of standards or IEC 61076-3-104, IEC 61076-3-110, IEC 61076-2-101
and IEC 61076-2-109. Where cables and/or connectors do not comply with these standards,
then additional tests may be required.
This standard is organized as follows:
• reference laboratory measurement procedures on cabling topologies are specified in
Clause 4. In some cases, these procedures may be used in the field (see
IEC TR 61156-1-2:2009/AMD1:2014);
• deions and requirements for measurements in the field are specified in Clause 5;
• performance requirements for field testers and procedures to verify performance are
specified in Clause 6.
NOTE 1 This standard does not include tests that are normally performed on the cables and connectors
separately. These tests are described in IEC 61156-1 and IEC 60603-7 or IEC 61076-3-104,
IEC 61076-3-110, IEC 61076-2-101 and IEC 61076-2-109, respectively.
NOTE 2 Users of this standard are advised to consult with applications standards, equipment manufacturers and
system integrators to determine the suitability of these requirements for specific networking applications.
It is assumed that cables and connectors used in cable assemblies, even if they are not
described in IEC 61156 or IEC 60603-7, IEC 61076-3-104, IEC 61076-3-110, IEC 61076-2-
101 and IEC 61076-2-109, are tested separately according to the tests given in the relevant
generic specification.
This standard relates to performance with respect to 100 ? cabling. For 120 ? or 150 ?
cabling, the same principles apply but the measurement system should correspond to the
nominal impedance level.
Field tester types include certification, qualification and verification. Certification testing is performed for the rigorous needs of commercial/industrial buildings to this standard. Qualification testing is described in IEC 61935-3. Qualification testing determines whether the cabling will support certain network technologies (e.g. 1000BASE-T, 100BASE-TX, 10G Base- T). Qualification testers do not have traceable accuracy to national standards and provide confidence that specific applications will work. Verification testers only verify connectivity.
Throughout this standard, 4-pair cabling is assumed. The test procedures described in this standard may also be used to evaluate two pair balanced cabling. However, 2-pair cabling links that share the same sheath with other links shall be tested as 4-pair cabling.dition 4.0 2015-12
