Household electrical appliances - Measurement of standby power

This International Standard specifies methods of measurement of electrical power consumption in standby mode. It is applicable to mains powered electrical household appliances and to the mains powered parts of appliances that use other fuels such as gas or oil. This standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption. The objective of this standard is to provide a method of test to determine the power consumption of a range of appliances and equipment in standby mode (generally where the product is not performing its main function). This standard defines "standby" mode as the lowest power consumption when connected to the mains. The test method is also applicable to other low power modes where the mode is steady state or providing a background or secondary function (e.g. monitoring or display). Annex A provides some guidance on the expected modes that would be found for various appliance configurations and designs based on their circuitry and layout, but the standard does not define these modes. The relevant low power modes (in addition to standby mode) to which this test procedure is applied should be defined by performance standards of appropriate appliances. As an example, IEC 62087 specifies a range of modes for TVs, VCRs and similar equipment.

- 3 - EN 62301:2005 Endorsement notice The text of the International Standard IEC 62301:2005 was approved by CENELEC as a European Standard with agreed common modifications as given below. COMMON MODIFICATIONS Introduction Add: The document is written as a specific measurement procedure and shall not normally be used on its own but as a referenced standard in a product performance standard. Thus where a product requires data on standby power, it shall be made by incorporation of a new clause in the product performance standard which makes reference to this standard and defines within that clause set-up data and control procedures. However since it will no doubt be used as a generic measurement method for appliances that have no performance standard or are “new” appliances, further modifications to EN 62301 will likely be needed in the future. The aim of the common modifications to the text of IEC 62301:2005 is to ensure the European Standard complies with the EU requirements for energy labelling. 4.3 Power supply Replace the second paragraph by: Where the test voltage and frequency are not defined by an external standard, the test voltage and test frequency shall be: • 230 V ± 1 % • 50 Hz ± 1 % If the appliances are to be connected to three phases and the test voltage and frequency are not defined by an external standard the test voltage and test frequency shall be: • 400 V ± 1 % • 50 Hz ± 1 % Delete Table 1.

Add the following new clause: Z1 Tolerances and control procedures Where tolerances and control procedures are not defined by an external standard, the tolerances and control procedures shall be according to the following. Z1.1 For power consumption greater than 1 W The standby power determined according to this standard on the first appliance shall not be greater than the value declared by the manufacturer plus 15 %. If the result of the test carried out on the first appliances is greater than the value declared plus 15 %, the test for standby power shall be carried out on a further three appliances, which shall be randomly selected from the market. The arithmetic mean of the values of these three appliances for the standby power shall not be greater than the declared value plus 10 %.

EN 62301:2005 - 4 - Z1.2 For power consumption less or equal to 1 W The standby power measured according to Clause 4 shall not be greater than the value declared by the manufacturer plus 0,15 W. If the result of the test carried out on the first appliance is greater than the declared value plus 0,15 W, the test shall be carried out on a further three appliances, which shall be randomly selected from the market. The arithmetic mean of the values of these three appliances shall not be greater than the declared value plus 0,1 W.

INTRODUCTION The methods defined in this standard are not intended to be used to measure power consumption of appliances and equipment during normal operation (“on” mode), as these are generally covered by IEC product standards (see Bibliography). This standard is intended to cover appliances and equipment that fall within the scope of IEC TC59. However, it is acknowledged that, if desired, it can be applied to the relevant low power modes of other similar products.

HOUSEHOLD ELECTRICAL APPLIANCES – MEASUREMENT OF STANDBY POWER

1 Scope This International Standard specifies methods of measurement of electrical power consump-tion in standby mode. It is applicable to mains powered electrical household appliances and to the mains powered parts of appliances that use other fuels such as gas or oil. This standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption. The objective of this standard is to provide a method of test to determine the power consumption of a range of appliances and equipment in standby mode (generally where the product is not performing its main function). This standard defines “standby” mode as the lowest power consumption when connected to the mains. The test method is also applicable to other low power modes where the mode is steady state or providing a background or secondary function (e.g. monitoring or display). Annex A provides some guidance on the expected modes that would be found for various appliance configurations and designs based on their circuitry and layout, but the standard does not define these modes. The relevant low power modes (in addition to standby mode) to which this test procedure is applied should be defined by performance standards of appropriate appliances. As an example, IEC 62087 specifies a range of modes for TVs, VCRs and similar equipment. NOTE 1 The measurement of energy consumption and performance of appliances during intended use are generally specified in the relevant product standards and are not intended to be covered by this standard. NOTE 2 The term “appliances” in this standard means household appliances or equipment.

3 Terms and definitions For the purposes of this document the terms and definitions contained in IEC 60050-131 and IEC 60050-300 as well as the following apply.

3.1 standby mode lowest power consumption mode which cannot be switched off (influenced) by the user and that may persist for an indefinite time when an appliance is connected to the main electricity supply and used in accordance with the manufacturer’s instructions NOTE The standby mode is usually a non-operational mode when compared to the intended use of the appliance’s primary function. The definition of standby mode in this standard is only applicable to the determination of standby power or standby energy consumption under this standard. 3.2 standby power average power in standby mode when measured in accordance with Clause 5. NOTE 1 The standby power is measured in watts.

NOTE 2 Refer to Annex C for examples of how to calculate energy consumption from power measurements. 3.3 rated power input power assigned to the appliance by the manufacturer 3.4 rated voltage voltage assigned to the appliance by the manufacturer 3.5 rated frequency frequency assigned to the appliance by the manufacturer 4 General conditions for measurements 4.1 General Unless otherwise specified, measurements shall be made under test conditions and with equipment specified in 4.2 to 4.5. 4.2 Test room The tests shall be carried out in a room that has an air speed close to the appliance under test of ≤0,5 m/s. The ambient temperature shall be maintained at (23 + 5) °C throughout the test. NOTE The measured power for some products and modes may be affected by the ambient conditions (e.g. illuminance, temperature). 4.3 Power supply Where this standard is referenced by an external standard or regulation that specifies a test voltage and frequency, the test voltage and frequency so defined shall be used for all tests.

62301  IEC:2005 – 15 –

Where the test voltage and frequency are not defined by an external standard, the test voltage and the test frequency shall be the nominal voltage and the nominal frequency of the country for which the measurement is being determined +1 % (refer to Table 1).

Table 1 – Typical nominal electricity supply details for some regions Country/Region Nominal voltage and frequency a Europe 230 V, 50 Hz North America 115 V, 60 Hz Japan b 100 V, 50/60 Hz China 220 V, 50 Hz Australia and New Zealand 230 V, 50 Hz a Values are for single phase only. Some single phase supply voltages can be double the nominal voltage above (centre transformer tap). The voltage between two phases of a three-phase system is 1,73 times single phase values. (e.g. 400 V for Europe). Thus these multiples of the listed

nominal voltage are also the nominal voltage for some appliances (e.g.

ovens and clothes dryers) in some markets. b “50 Hz” is applicable for the Eastern part and “60 Hz” for the Western part, respectively.

4.4 Supply voltage waveform The total harmonic content of the supply voltage when supplying the appliance under test in the specified mode shall not exceed 2 % (up to and including the 13th harmonic); harmonic content is defined as the root-mean-square (r.m.s.) summation of the individual components using the fundamental as 100 %. The ratio of peak value to r.m.s. value of the test voltage (i.e. crest factor) shall be between 1,34 and 1,49. 4.5 Power measurement accuracy Measurements of power of 0,5 W or greater shall be made with an uncertainty of less than or equal to 2 % at the 95 % confidence level. Measurements of power of less than 0,5 W shall be made with an uncertainty of less than or equal to 0,01 W at the 95 % confidence level. The power measurement instrument shall have a resolution of: – 0,01 W or better for power measurements of 10 W or less; – 0,1 W or better for power measurements of greater than 10 W up to 100 W; – 1 W or better for power measurements of greater than 100 W. For appliances connected to more than one phase, the power measurement instrument shall be equipped to measure total power of all phases connected. NOTE See Annex D and the Guide to the Expression of Uncertainty in Measurement (GUM) for further details. 5 Measurements 5.1 General The purpose of this test method is the determination of the standby power, which in principle persists for an indefinite period of time. However, it is considered sufficient to measure over a limited period of time as given in 5.3.

62301  IEC:2005 – 17 –

NOTE 1 Some appliances may wait in a higher power state after they are switched off (or after the power is first connected) before dropping back to a lower state, or they may take some time to drop back to a lower state. NOTE 2 Where the mode changes automatically, it may be necessary to operate a product through the automatic sequence several times on a trial basis to ensure that sequence is fully understood and documented before test results are recorded and reported. Refer to Annex B for further guidance. Under this standard, power consumption may be determined: – where the power value is stable, by recording the instrument power reading; or – where the power value is not stable, by averaging the instrument power readings over a specified period or, alternatively by recording the energy consumption over a specified period and dividing by the time. NOTE 3 Determination of an average power from accumulated energy over a time period is equivalent. Energy accumulators are more common than functions to average power over a user specified period. 5.2 Selection and preparation of appliance or equipment Tests in this standard are to be performed on a single appliance. The appliance shall be prepared and set up in accordance with the manufacturer’s instruc-tions, except where these conflict with the requirements of this standard. If no instructions are given, then factory or “default” settings shall be used, or where there are no indications for such settings, the appliance is tested as supplied. For portable appliances with a rechargeable battery, standby mode is measured on the charger or docking/base station with the appliance detached. NOTE For the purposes of this test procedure, a portable appliance is one that is intended to operate on rechargeable batteries when not connected to a power source. 5.3 Procedure 5.3.1 Where the selected mode is stable This methodology may only be used where the mode and measured power are stable. A variation of less than 5 % in the measured power over 5 min is considered stable for the purposes of this standard. Instrument power readings may be used in this case. Connect the product to be tested to the metering equipment, and select the mode to be measured. After the product has been allowed to stabilize for at least 5 min, monitor the power consumption for not less than an additional 5 min. If the power level does not drift by more than 5 % (from the maximum value observed) during the latter 5 min, the load can be considered stable and the power can be recorded directly from the instrument at the end of the 5 min. 5.3.2 All other measurements This methodology shall be used where either the mode or measured power is not stable. However, it may also be used for all stable modes and is the recommended approach if there is any doubt regarding the behavior of the appliance or stability of the mode. Average power readings or accumulated energy over a user-selected period are used in this case. Connect the appliance (equipment) to the metering equipment. Select the mode to be measured (this may require a sequence of operations and it may be necessary to wait for the equipment to automatically enter the desired mode) and monitor the power. Average power is determined using either the average power or accumulated energy approaches outlined below.

62301  IEC:2005 – 19 –

a) Average power approach: where the instrument can record a true average power over a user selected period, the period selected shall not be less than 5 min (except if there is an operating cycle – see below). b) Accumulated energy approach: where the instrument can accumulate energy over a user selected period, the period selected shall not be less than 5 min (except if there is an operating cycle – see below). The integrating period shall be such that the total recorded value for energy and time is more than 200 times the resolution of the meter for energy and time. Determine the average power by dividing the accumulated energy by the time for the monitoring period. NOTE 1 To ensure consistent units, it is recommended that watt-hours and hours be used above, to give watts. NOTE 2 Example 1 – if an instrument has a time resolution of say 1 s, then a minimum of 200 s (3,33 min) is required for integration on such an instrument.

NOTE 3 Example 2 – if an instrument has an energy resolution of say 0,1 mWh, then a minimum of 20 mWh is required for an integration on such an instrument (at a load of 0,1 W this would take about 12 min, at 1 W this would take 1,2 min). Note that both the time and energy resolution requirements should be satisfied by the reading. If the power varies over a cycle (i.e. a regular sequence of power states that occur over several minutes or hours), the period selected to average power or accumulate energy shall be one or more complete cycles in order to get a representative average value. In case of accumulated energy the integrating period shall be as described above. 6 Test report The following information shall be recorded in the test report: 6.1 Appliance (equipment) details • Brand, model, type, and serial number • Product description, as appropriate • Rated voltage(s) and frequency(frequencies)

• Details of manufacturer marked on the product (if any) In the case of products with multiple functions or with options to include additional modules or attachments, the configuration of the appliance as tested shall be noted in the report. 6.2 Test parameters • Ambient temperature (°C) • Test voltage(s) (V) and frequency (frequencies) (Hz) • Total harmonic distortion of the electricity supply system • Information and documentation on the instrumentation, set-up and circuits used for electrical testing

62301  IEC:2005 – 21 –

6.3 Measured data, for each mode as applicable • Average power in watts rounded to the second decimal place. For loads greater than or equal to 10 W, three significant figures shall be reported. • Measurement method used (refer to 5.3.1 and 5.3.2) (in the case of 5.3.2, indicate whether average power or accumulated energy approach was used) • Accumulated energy and period of measurement (seconds/minutes/hours) (if applicable) • Description of how the appliance mode was selected or programmed • Sequence of events to reach the mode where the equipment automatically changes modes • Any notes regarding the operation of the appliance (equipment) NOTE App
