5 Test parameters for balanced copper cabling
5.1 Wire map
Test method: see EN 61935-1:2009, 5.3.2.2.
5.2 Length
5.2.1 Test method
See EN 61935-1:2009, 5.3.4.
5.2.2 Documentation
The measured results shall be reported in tabular format. The test report shall also include the nominal
velocity of propagation used in any calculation of the measured result.
5.3 Propagation delay
5.3.1 Test method
See EN 61935-1:2009, 5.3.3.
5.3.2 Documentation
The measured results shall be reported in tabular format. The test report shall also include the requirements
of the relevant cabling or application standard and the measurement accuracy.
Results for all pairs shall be reported. It shall be explicitly noted if the measured results do not conform to the
requirements.
5.4 Delay skew
5.4.1 Test method
See EN 61935-1:2009, 5.3.3.
5.4.2 Documentation
The measured results shall be reported in tabular format. The test report shall also include the requirements
of the relevant cabling or application standard and the measurement accuracy.
It shall be explicitly noted if the measured results do not conform to the requirements.
5.5 Attenuation (insertion loss)
5.5.1 Parameter
The term attenuation, widely used throughout the cabling industry, refers to a parameter more correctly
described and measured as “insertion loss”. In this standard the two terms are used in parallel with the
understanding that the parameter measured is “insertion loss”.
– 7 – EN 50346:2002/A2:2009
5.5.2 Test method
See EN 61935-1:2009, 5.3.5, for the measurement of attenuation (insertion loss) on installed cabling at
frequencies up to 600 MHz using portable field test equipment.
5.5.3 Documentation
The measured results shall be reported in tabular or graphical format. The test report shall also include the
requirements of the relevant cabling or application standard and the measurement accuracy.
Results for all pairs shall be reported. It shall be explicitly noted if the measured results do not conform to the
requirements.
5.6 Attenuation (insertion loss) deviation
For further study.
5.7 Near end crosstalk loss (NEXT, pair-to-pair and power sum)
5.7.1 Test method
See EN 61935-1:2009, 5.3.6, for the measurement of NEXT (pair-to-pair and power sum) on installed cabling
at frequencies up to 600 MHz using portable field test equipment.
It is possible to use laboratory test equipment to perform tests under the following conditions:
a) the cable within the cabling interface adaptor shall be as short as possible;
b) for the measurement of screened cabling, the screen terminations of the cabling interface adaptor shall
be of low impedance.
5.7.2 Documentation
The measured results shall be reported in graphical or tabular format. The test report shall also include the
requirements of the relevant cabling or application standard and the measurement accuracy.
Results for all pairs shall be reported. It shall be explicitly noted if the measured results do not conform to the
requirements.
5.8 Equal level far end crosstalk loss (ELFEXT, pair-to-pair and power sum)
5.8.1 Test method
See EN 61935-1:2009, 5.3.8, for the measurement of ELFEXT (pair-to-pair and power sum) at frequencies
up to 600 MHz using portable field test equipment.
The measurement of ELFEXT using laboratory test equipment requires synchronization between local and
remote test equipment. Where such equipment is used
a) the cable within the cabling interface adaptors shall be as short as possible,
b) for the measurement of screened cabling, the screen terminations of the cabling interface adaptors shall
be of low impedance.
The measurement of ELFEXT using laboratory test equipment without synchronization between local and
remote test equipment is not supported by this standard.
5.8.2 Documentation
The measured results shall be reported in graphical or tabular format. The test report shall also include the
requirements of the relevant cabling or application standard and the measurement accuracy.
Results for all pairs shall be reported. It shall be explicitly noted if the measured results do not conform to the
requirements.
5.9 Attenuation to crosstalk ratio far end (ACR-F, pair-to-pair and power sum)
5.9.1 Test method
See EN 61935-1:2009, 5.3.8, for the measurement of ACR-F (pair-to-pair and power sum) at frequencies up
to 600 MHz using portable field test equipment.
The measurement of ACR-F using laboratory test equipment requires
