The
28、 voltage and frequency used during the power measurement shall be described in the report. The fluctuation of the voltage supplied during the tests shall not exceed 2 %. The frequency fluctuation and the harmonic components of the supplied power shall not exceed 2 % and 5 % respectively. 5.1.2 Envir
29、onmental conditions Ambient temperature 15 C to 35 C, preferably 20 C, unless otherwise specified in this standard. The ambient temperature shall be described in the report. 5.1.3 Adjustment of controls The controls not specifically mentioned in this standard shall be in the position adjusted by the
30、 manufacturer for shipment to the end user. These controls shall remain in this state for the duration of the test. 5.1.4 Input signals For equipment for which the input signals are not explicitly described in this standard, the nominal signals as specified by the manufacturer shall be applied durin
31、g the test. The input signals used shall be described in the report. 5.1.5 Power Measurement Instrument The measurement shall be carried out directly by means of a wattmeter, a wattmeter with averaging function, or a watthour meter by dividing the reading by the measuring time. For television sets,
32、in the case that the input video signal varies over time, a wattmeter without an averaging function shall not be used to carry out the measurement. The sampling rate of the watthour meter or wattmeter with averaging function should be high enough to achieve an accurate measurement. The power measure
33、ment instrument used shall measure the real power consumed regardless of the power factor of the device under test. 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
34、 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 pow
35、er measurements of greater than 100 W. For equipment connected to more than one phase, the power measurement instrument shall be equipped to measure total power of all phases connected. Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 29 Apr 2009 COPYRIGHT 6 NOTE 1 In the case of standby mode power meas
36、urement, it should be ascertained that the wattmeter or the watthour meter is suitable to measure the power consumption of power supplies working in a burst mode with a low duty cycle and the low power consumption levels in the standby modes. NOTE 2 For digital power meters a sampling rate of at lea
37、st 10 kHz is recommended. (“Sampling rate” in many specifications refers to how often the display is updated, and not the actual sampling frequency of the input waveform.) Most digital power meters are believed to meet this requirement. If it is not listed in the manufacturers specifications, contac
38、t the manufacturer. NOTE 3 For more information about the determination of uncertainty of measurement, refer to IEC 62301: 2005, Annex D. 5.2 General measurement procedure The following measurement procedure shall be used, unless otherwise specified in this standard. Measure the power consumption of
39、 the appliance at a time not less than 15 minutes after it has been switched into the relevant operating mode. If the power consumption in a certain operating mode has more than one stable level, the measuring time shall be of an appropriate duration to measure the correct average value. Some applia
40、nces switch, after a time delay, from a standby mode to a mode with a lower (or zero) power consumption. The power consumption before and after the switching shall be determined. For equipment with less functionality than described, for example playback tape equipment, only the relevant parts of the
41、 measuring conditions have to be considered. The results shall be given in watts (W), with a number of relevant digits in accordance with the accuracy of the measurement. NOTE If in the measuring conditions, the standby mode is mentioned without further specification, the standby modes as defined in
42、 clause 4 are referred to. 6 Measuring conditions for television sets, excluding On (average) mode 6.1 Input signal RF or baseband If an RF input is available, this shall be used. 6.2 RF input signal At a level to provide a sufficiently noise-free or error-free picture. 6.3 Baseband input signal lev

44、acturer. Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 29 Apr 2009 COPYRIGHT 7 6.6 Loading of terminals The loudspeaker terminals should be terminated with the minimum impedance as specified by the manufacturer. 6.7 On (play) mode NOTE On (play) mode remains from the previous version (IEC 62087: 2002
45、) for backward compatibility. For measuring television set power consumption, On (average) mode, defined in clause 11, is recommended. Contrast and brightness are adjusted to obtain the luminance values as specified in 3.6.2 of IEC 60107-1:1997. If the levels cannot be adjusted to the stated values,
46、 the actual values shall be described in the report. If this setting is not practicable, a setting defined by the manufacturer shall be used. The actual setting shall be listed in the measuring report. Volume control adjusted to obtain 50 mW at the loudspeaker terminals. In case of TVs with surround
47、 sound facility, only the front speaker terminals shall be loaded. Television sets with wide screen display shall be measured in the wide screen mode. 6.8 Standby mode Only those conditions apply which are relevant for the standby mode. 6.9 Off mode Only those conditions apply which are relevant for
48、 the off mode. 7 Measuring conditions for video recording equipment 7.1 Input signal RF or baseband If an RF input is available, this shall be used. 7.2 RF input signal At a level to provide a sufficiently noise-free or error-free picture at play-back. 7.3 Baseband input signal level According to EN
49、 50049-1 or AS 4542.2. 7.4 On mode Record or playback mode with tape or disc specified by the manufacturer at standard speed. 7.5 Standby mode Only those conditions apply which are relevant for the standby mode. 7.6 Off mode Only those conditions apply which are relevant for the off mode.
