Verify the original report, whether the EUT is equipped with or specified to be equipped with passive EMI suppression components when in use, and whether the nuisance power test is conducted in accordance with the requirements of the new version of the standard. If there is and not according to the new version of the standard requirements of the test, need to be in accordance with the new version of the standard requirements of the nuisance power project layout and testing.

Under the operating conditions specified in this document, the observation time T shall be determined only at 150 kHz and 500 kHz The following procedure shall be used to determine the minimum observation time.

If the EUT is not run under program control, the minimum observation time is the shorter of the following: a)

The number of minutes to count 40 clicks on one of the two frequency points; or e120 min.

If the EUT does run according to the program, the minimum observation time is the duration of the full program if the click rate obtained from the full program is less than or equal to 0.5 and the program duration b) is greater than 20 min. Otherwise.

If the click rate is determined by counting the number of switching operations instead of the number of clicks, the same procedure shall be used. When case b) applies, the interval between the end of one program and the manual start of the next program shall be excluded from the minimum observation time.

Verification of the original report requires retesting of the intermittent nuisance item, except for the apparatus for which the original report used the number of switching operations to determine the clicking rate and the apparatus excluded by example 4.4.1.

During the test, the EUT shall be operated at the rated voltage specified for the equipment. For single-phase equipment with rated voltages in the following ranges.

-100V~127V, the test shall be carried out at one of the nominal voltages within the range, the recommended test voltage being 120V.

-200V~240V, the test shall be carried out at one of the nominal voltages within the range, the recommended test voltage being 230V.

-100V~240V, the test shall be conducted at one nominal voltage within the range of 100V~127V or one nominal voltage within the range of 200V~240V, except that the user of this document may test the equipment twice, once at one nominal voltage within the range of 100V~127V and once at one nominal voltage within the range of 200V~240V, and this decision shall be documented in the test report. The decision shall be recorded in the test report.

Where applicable, the above requirements also apply to the AC power port of the EPS. Multiphase equipment shall be tested using the same principles as described above for three-phase equipment with rated voltages in the following ranges.

200V~240V, the test shall be carried out at one of the nominal voltages within this range: the recommended test voltage is 220V.

6.2.2 AC Power Port Frequency

During the test, the EUT shall be operated at the rated frequency specified for the equipment.

If the equipment has more than one rated frequency (e.g., 50 Hz to 60 Hz), the EUT shall be tested at only one of these frequencies.

If the equipment has a rated frequency range (e.g., 50 Hz to 60 Hz), the EUT shall be tested at a frequency within that range.

6.3.1 Battery power

When testing battery-powered EUTs, the type of battery used and its connection shall be as specified in the instructions for use. If the instructions specify the use of batteries of different ratings, it is preferable to use batteries of the largest capacity (e.g., Ah). A fully charged battery shall be used at the beginning of each test. During the test, the battery conditions shall be sufficient to maintain normal operating conditions. If the batteries are charged from an AC power source, the equipment shall be considered to be grid-powered in this mode of operation.

6.3.2 Non-battery powered DC supply

During the test, the EUT shall be operated with typical power supplies at the rated voltage specified for the DC power supply unit. DC power supply equipment operating with a dedicated DC power supply unit (e.g., EPS) shall be tested in accordance with the DC power supply unit specified or recommended in the instructions for use. If a DC power supply unit is not specified or recommended in the instructions for use, or is not available at the time of testing, a typical power supply specified by the equipment to provide the rated voltage and current shall be used. The typical power supply selected shall be sufficient to meet the specifications of the EUT and shall meet the limits of this document when operated alone (see A.8.8 or A.8.9).

The typical power supply used should be documented in the test report.

1) Test requirements for battery powered equipment;

(2) Test requirements for non-battery-powered DC equipment: It should be tested with a typical power supply that meets the requirements specified in the manual or configured in the laboratory.

Verify in the original report that the EUT is powered by a DC power supply unit and that only the battery operating condition was tested without the DC power supply unit. If so, additional testing with a DC power supply unit is required.

Unless otherwise specified herein, equipment with a lighting function shall be tested under the operating conditions specified in Appendix A with the lighting function at its maximum setting. If the equipment meets all the requirements of this document, 6.5 does not apply to the lighting function.

Alternatively, if the lighting function of such equipment can be tested separately, the lighting function can be tested in accordance with the requirements of GB/T17743, and the rest of the equipment functions are tested in accordance with this document, and the lighting function is not activated.

If the lighting function is not intended to be turned on continuously during normal operation, it is not necessary to test the lighting function. Note: A range hood is an example of a product whose lighting function can be turned on continuously during normal operation. A refrigerator is an example of a product whose lighting function is not intended to be turned on continuously during normal operation because the lights are off when the door is closed.

EUT contains "can continuously turn on the lighting function during operation", and did not pass the GB/T17743 test, you need to turn on the lighting during the test to supplement all the test items.

The provisions of A.10 shall apply to the mode of operation during TPT start-up. When this is done, functions that are not powered by energy obtained from the IPT may be switched off and tested separately.

Note 1: For example, the display portion of the IPT charging cradle can be powered directly from the grid rather than through the IPT power circuit.

NOTE 2: Examples of functions that may be tested individually are: display sections on IPT charging cradles that can be turned off by the user or automatically by the equipment, or accessories that can be removed by the user In addition to the provisions in A.10, the normal provisions shall apply to the IPT in its unactivated mode of operation.

NOTE 3: For example, massage equipment may be charged using a dedicated IPT charging cradle (operation mode 1, see case 3 of A.10) and used when IPT charging is stopped (operation mode 2. See A.1.5).

Verify that equipment with IPT capability has been tested, and if not, additional testing is required.

Refrigerator and freezer should be closed for continuous operation. The thermostat is adjusted to the middle of the adjustment range. The box should be empty and unheated Measurements should be made after it has reached a steady state.

The light inside the chamber shall be turned off during measurements, unless the light can be turned on by the user with the door closed or can be turned on continuously during normal operation.

Note 1:The light in the wine cooler with glass doors is an example of a continuously on light.

If the click is not measured, the click rate N is determined as half the number of switching operations.

NOTE 2: Due to ice buildup on cooling elements, the number of switching operations in normal use is approximately half that of an empty refrigerator.

A.1.20.1 If the temperature of the air is controlled by varying the interval between compressor runs in the appliance, or if the appliance has a heater controlled by a thermostat, the measurements shall be made under the same operating conditions as specified in A.4.14. A.1.20.2 If the appliance is in the variable capacity mode with inverter circuits controlling the speed of the fan or the compressor, the measurement is made with the thermostat set at the lowest temperature in the cooling mode and at the highest temperature in the heating mode. A.1.20.3 For equipment tested in accordance with A.1.20.1 and A.1.20.2, the ambient temperature shall be (15 ½) °C when the equipment is operated in the heating mode and (30 ½) °C when the equipment is operated in the cooling mode. If it is impractical to maintain the ambient temperature within this range, other temperature ranges are permissible as long as the equipment can be operated in a steady state.

Ambient temperature is defined as the temperature of the air flowing to the indoor unit.

A.1.20.4 If the appliance consists of an indoor unit and an outdoor unit (split type), the length of the connecting refrigeration tube shall be (5±0.3) m and shall be coiled, if possible, into a loop of approximately (1±0.3) m in diameter. If the length of the connecting tube cannot be adjusted, the connecting tube shall be longer than 4 m, but not longer than 8 m.

For indoor and outdoor unit connection line nuisance power measurement, the connection line should be separated from the cooling tube and extended to meet the absorption clamp measurement. For other nuisance power and nuisance voltage measurements, the connecting wires of the two parts shall be arranged along the refrigeration tubes. When there is a requirement for a ground wire that is not part of the power lead, the earth terminal of the outdoor unit shall be connected to a reference earth (see 5.2.1, 5.2.2 and 5.2.3). For nuisance voltage measurements, the AMN shall be placed at a distance of 0.8 m from the unit (indoor unit or outdoor unit) connected to the AC power grid or, for nuisance voltage or nuisance power measurements, the test arrangement in A.1.20.5 may also be used. For the purpose of determining the starting frequency of the nuisance voltage or nuisance current test at ports other than the AC power port, if the length of the connecting leads is not specified in the instructions for use, it shall be assumed that the length of the leads is always greater than 2 m, but less than 30 m. NOTE: Due to limitations in the range of refrigerant tubes, the length of the connecting leads is always expected to be less than 30 m.

1)Current Probe Test Methods；

2) Radiated nuisance test method

The washing machine should be operated with water but without fabric, and the temperature of the incoming water should be in accordance with the instructions for use.

Continuous harassment was evaluated only during the normal washing mode of cotton fabrics and during the spinning mode at maximum speed.

For the assessment of continuous harassment, infrequent short-term events are not considered if they do not last more than a few seconds, e.g., during the beginning of the dewatering cycle.

For the assessment of intermittent nuisance, if there is a 60°C washing program for cotton fabrics without pre-wash, measurements are made using the full program: otherwise measurements are made using the regular washing program without pre-wash.

NOTE: If there is a washer with a dryer function as part of the overall program, see A.1.12 or A.1.13.

(a) water leakage protection valves are not peripheral devices within the meaning of this document and measurements on the leads of these valves are not required.

In the nuisance power measurement of the power supply lead, the water leakage protection hose shall be connected to the faucet, with a length of (0.4±0.05) m and the power supply lead arranged in parallel, with a maximum distance of 0.1 m. Then the power supply lead shall be measured according to the requirements of 5.3.3.2.

A.1.1.1 Vacuum cleaners shall be measured in continuous operation without accessories and with an empty dust bag. Vacuum cleaners with power lead reels shall be measured with the power leads pulled out completely and arranged in accordance with 5.2.2.1.

A.1.1.2 Measurements of nuisance voltage and nuisance current do not apply to leads integrated in the vacuum hose (see 4.3.3.3). A.1.1.3 If applicable, in addition to measurements of the power supply leads, nuisance power measurements shall be made on leads integrated in the vacuum hose if the plugs or sockets on the leads are readily replaceable by the user. The measurement shall be made by replacing the vacuum hose and its integrated lead with a cable of the necessary length to be connected to the terminals on the main unit and with the same number of wires as in the originally fitted vacuum hose.A.1.1.4 The power nozzle of the vacuum cleaner shall be operated continuously without mechanical loading of the brushes. If required, cooling shall be provided without unduly affecting the test results. The required cooling airflow shall be achieved without metal fixtures in the vicinity of the nozzle.

If the powered nozzles are connected by non-extendable power leads with an overall length shorter than 0.4 m, or if they are connected directly to the vacuum cleaner by plugs and sockets, they shall be measured together. In all other cases, the EUT shall be measured separately.

....

Verification of the original report, the vacuum cleaner was tested for radiated nuisance and was not arranged in accordance with the requirements of the new version, it is necessary to supplement the radiated nuisance test in accordance with the requirements of the new version of the standard.

The iron shall be operated with the soleplate cooled with air, water or oil. The heating control shall be set at the maximum temperature at (50 s.10)% duty cycle. The clicking rate N may be determined by the number of switching operations (f = 0.66 in Table B.1).

Clothing irons that do not produce steam should be placed on a three-point pointed metal support at least 100 mm high, with the soleplate in a horizontal position, and cooled by air-cooling. The heating control should be set to the middle of the maximum temperature range available on the iron. Note: For an example of a metal support see IEC 60335-2-3:2012, 11.2.

Clothing irons with a steam function should be set on the same stand as above for irons without a steam function. No additional cooling is required. The steam function should be switched on. In particular.

-For irons capable of providing continuous steam, the steam control shall be set for continuous steam; for irons capable of providing steam injection, the steam control shall be set for continuous steam, if available, or for steam injection at a rate of one minute.

The jetting operation is performed in a rhythm of 3 times.

The test report should detail the settings selected for the test.

Clothing irons can be rated for clicking using Appendix B.

Intermittent nuisance is a transient nuisance with broadband characteristics, usually generated by switching operations. The effect of the harassment depends not only on the amplitude of the clicks, but also on the duration, spacing and repetition rate of the clicks. Since the amplitude and duration of individual clicks are not constant, a specific statistical evaluation method was developed in order to test the necessary reproducibility of the results. Intermittent disturbances are considered to cause less interference than continuous disturbances of the same amplitude, and therefore the limits for such disturbances have been relaxed in this document.

The CISPR limits are based on the recommendation that for type-approved equipment, it is desirable that the batch should comply with the limits at least 801 TP3T with a statistical base confidence level of at least 801 TP3T.

The CISPR limits are based on statistical methods to take into account the actual and inherent variability of EMC performance of high-volume equipment Type tests are generally performed on a representative sample prior to mass production and sale. Therefore, it is appropriate for the type test to.

In at least 3 samples according to one of the methods given below: or a)

For simplicity, this was done on one sample only. b)

For the assessment of intermittent harassment, option b) is preferred.

It is desirable to carry out random follow-up testing of equipment in production from time to time, especially if option b) above is followed.

The new version of the standard turns the method into an informative appendix.
