FOREWORD
GB/T6113 “Specification for radio disturbance and immunity measuring apparatus and
methods”, a basic standard of electromagnetic compatibility, consists of the following
four parts:
Part 1: Radio disturbance and immunity measuring apparatus
-- Part 1-1: Radio disturbance and immunity measuring apparatus - Measuring
equipment;
-- Part 1-2: Radio disturbance and immunity measuring apparatus - Coupling devices
for conducted disturbance measurements;
-- Part 1-3: Radio disturbance and immunity measuring apparatus - Ancillary
equipment - Disturbances power;
-- Part 1-4: Radio disturbance and immunity measuring apparatus - Radiated
disturbance measuring antenna and test site;
-- Part 1-5: Radio disturbance and immunity measuring apparatus - Antenna
calibration sites and reference test sites for 30 MHz to 1000 MHz
-- Part 1-6: Radio disturbance and immunity measuring apparatus - EMC antenna
calibration.
Part 2: Methods of measurement of disturbances and immunity
-- Part 2-1: Methods of measurement of disturbances and immunity - Conducted
disturbance measurements;
-- Part 2-2: Methods of measurement of disturbances and immunity - Measurement
of disturbance power;
-- Part 2-3: Methods of measurement of disturbances and immunity - Radiated
disturbance measurements
-- Part 2-4: Methods of measurement of disturbances and immunity - Immunity
measurements;
-- Part 2-5: In situ measurements of disturbing emissions produced by physically
large equipment
Part 3: CISPR technical reports
-- Part 3: CISPR technical reports.
Part 4: Uncertainties, statistics and limit modelling
-- Part 4-1: Uncertainties, statistics and limit modelling - Uncertainties in
standardized EMC tests;
-- Part 4-2: Uncertainties, statistics and limit modelling - Measurement

-- Part 4-4: Uncertainties, statistics and limit modelling - Statistics of complaints and
a model for the calculation of limits;
-- Part 4-5: Uncertainties, statistics and limit modelling - Conditions for the use of
alternative test methods.
This Part is Part 1-2 of GB/T 6113.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces GB/T 6113.102-2008 "Specification for radio disturbance and
immunity measuring apparatus and methods - Part 1-2: Radio disturbance and
immunity measuring apparatus - Ancillary equipment - Conducted disturbances".
Compared with GB/T 6113.102-2008, the main technical changes are as follows:
-- Modify the standard’s name;
-- Add a "Note" to the scope according to the principle of equivalence;
-- Add 7 terms and definitions (see Clause 3);
-- Add abbreviations (see 3.2);
-- Add longitudinal conversion loss requirements for AAN (or Y-network) for
common-mode voltage measurement of category 6 (or better), category 5 (or
better), and category 3 (or better) unscreened balanced pair cables (see 7.2);
-- Add CDNE for the measurement of disturbance voltage in the frequency range of
30 MHz ~ 300 MHz (see Clause 9);
-- Add Example CDNE set-up diagrams (see Annex J).
This Part uses the translation method to equivalently adopt CISPR 16-1-2:2014
"Specification for radio disturbance and immunity measuring apparatus and methods -
Part 1-2: Radio disturbance and immunity measuring apparatus - Coupling devices for
conducted disturbance measurements".
