AS NZS 61000.6.3:2021 – Electromagnetic compatibility (EMC) Part 6.3: Generic standards — Emission standard for equipment inresidential environments (IEC 61000-6-3:2020(ED 3.0) MOD)

Measurements shall be applied to the relevant ports of the equipment specified in Table 3 to Table 6. Measurements shall only be carried out where the relevant ports exist
All tests defined in Table 3 to Table 6 shall be considered by the test plan, however, where it has been determined in the test plan, that one or more of the tests are not applicable, the decision and justification not to perfomi such tests shall be recorded in the test report See examples
EXAMPLE Whon considonng a lost plan 1o an EUT. which iC always powered through a UPS then condi,cted tests on the low voltage Ac mains port are not necessary.
The requirements are given in Table 3 to Table 6
9 Measurement uncertainty
Where guidance for the calculation ol the instrumentation uncertainty of a measurement is specified in CISPR 16-4-2. this shall be lollowed. For these measurements the determination ol compliance with the limits in this document shall take into consideration the measurement instrumentation uncertainty in accordance with CISPR 16-4-2. Calculations to determine the measurement result and any adjustment of the test result required when the test laboratory uncertainty s larger than the value for cispr given in CISPR 16-4-2 shall be included in the test report.
10 Compliance with this document
Where this document gives options for testing particular requirements with a choice of test methods, compliance can be shown against any of the relevant test methods, using the specified lImits within the restrictions provided in the relevant table clauses. For example, floor standing equipment shall be assessed against table clause 3.1. considering table clause 3.2 is limited to small equipment and table clause 3.3 Is limited to table top equipment.
In any situation where it is necessary to retest the equipment, the lest method originally chosen shall be used in order to ensure consistency of the results
The test report shall contain sufficient details to facilitate reproducibility of the measurements
Equipment which fulfills the requirements across the frequency ra,ges specified in Table 3 to Table 6. in this document is deemed to fulfill the requirements in the entire frequency range up to 400 GHz.
Measurements do not need to be performed at frequencies where no limits are specified.
11 Emission test details
The following shall be taken into account during the application of the measurements defined in Table 3 to Table 6
• At transitional frequencies, the lower limit applies
• Where the limit value varies over a given frequency range, it changes linearly with respect to the logarithm of the frequency.
• The test site shall be validated for the measurement distance chosen.
For all other measurements, the entire frequency range shall be measured
• For emission measurements above 1 GHz. the peak detector limits shall not be applied to disturbances produced by arcs or sparks that are high voltage breakdown events Such disturbances arise when devices contain or control mechanical switches that control current in inductors, o when devices contain or control subsystems that create static electricity (such as paper handling devices). The average limits apply to disturbances from arcs or sparks, and both peak and average limits will apply to all other disturbances from such devices
• For radiated emission measurements using a FSOATS, OATS. FAR or SAC, the measurement distance is the shortest horizontal distance between the vertical projections of the calibration point of the receiving antenna and the boundary of the EUT. when typically arranged and rotated through 360.
For frequencies below 1 GHZ, a maximum of 1.6 m of cabling shall be considered as part of the EUT.
The boundary of the EUT is the smallest imaginary circular periphery around the most compact arrangement of the EUT, using typical spacing, see 7 3.1 in CISPR 16-2-3:2016
Antennas shall be calibrated in free space conditions using facilities defined in CISPR 16-1.5:2014 and CISPR 16-1-5:2O14IAMD1.2016 whilst using the procedures defined In CISPR 16-1-6:2014 and CISPR 16-1-6,2014!AMD1:2017
• Where this document specifies the use of an average detector, the linear average detector defined In Clause 6 of CISPR 16-1-1:2019 shall be used
• With regard to conducted emissions on power lines, care shall be taken to ensure emissions below 150 kHz do not impact the measurements This Is typically achieved using a high pass filter and an attenuator.
