FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62087-1 has been prepared by technical area 12: AV energy

efficiency and smart grid applications, of IEC technical committee 100: Audio, video and

multimedia systems and equipment.

IEC 62087-1:2015 © IEC 2015 – 9 –
5.1.1.2 External power supplies

Equipment supplied by the manufacturer with an external power supply shall be connected to

that external power supply during the measuring procedures.
5.1.1.3 Mains power

For equipment powered by the mains, the equipment shall be powered using the declared

voltage and frequency of the region.
The voltage and frequency of the power source shall be reported.
NOTE Annex B provides additional information regarding electricity supplies.
5.1.1.4 Power from other than the mains

For equipment powered by a means other than the mains, the equipment shall be powered at

the voltage and frequency as specified by the manufacturer.
The voltage and frequency of the power source shall be reported.
5.1.1.5 Power source, On mode
In On mode, the following requirements apply:

The fluctuation of the voltage supplied shall not exceed ±2 %. The frequency fluctuation and

the harmonic components of the supplied power shall not exceed ±2 % and 5 % respectively.

5.1.1.6 Power source, Partial On and Off modes
In the Partial On and Off modes, the following requirements apply:

The test voltage shall be the declared voltage ±1 % and the test frequency shall be the rated

frequency ±1 %. Where a number of models of equipment are being tested and compared for

use in the same country, the declared voltage ±1 % and declared frequency ±1 % may be

used for all tests. Where the test voltage and frequency are not defined by an external

standard, the test voltage and the test frequency shall be the declared voltage and the

declared frequency of the country for which the power consumption is being determined ±1 %.

The total harmonic content of the source voltage when supplying the UUT 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.
NOTE 1 Annex B provides additional information regarding electricity supplies.
NOTE 2 A stabilized power supply may be required to meet these requirements.
5.1.2 Environmental conditions

The ambient temperature of the test room shall be 23 °C ± 5 °C, unless otherwise specified in

this series of standards. The ambient temperature shall be reported.
---------------------- Page: 11 ----------------------

5.1.3 Adjustment of controls

The controls not specifically mentioned in this part or other parts of IEC 62087 shall be in the

position adjusted by the manufacturer for shipment to the end user. These controls shall

remain in this state for the duration of the test unless otherwise directed.
5.1.4 Input signals

For equipment for which the input signals are not explicitly described in this standard, the

signals as specified by the manufacturer shall be applied during the test. The input signals

used shall be reported.
5.1.5 Power measuring 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. If the

power consumption is expected to vary over time, such as in the case of a television set

displaying a dynamic signal, a watthour meter or a wattmeter with an averaging function shall

be used to carry out the measurement.

The sampling rate of the watthour meter or wattmeter with averaging function shall be high

enough to achieve an accurate measurement. The manufacturer’s specification shall be used

to determine the appropriateness of the meter and suitable sampling rates to perform a

measurement with the required accuracy.

The power measuring instrument used shall measure the real power consumed regardless of

the power factor of the UUT.

In the case of Partial On mode power measurement, 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 Partial On mode.

For digital power meters, a sampling rate of at least 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 manufacturer’s specifications, contact the manufacturer.

5.1.6 Measurement uncertainty

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 measuring 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 equipment connected to more than one phase, the power measuring instrument shall be

equipped to measure the total power of all phases connected.

NOTE For more information about the determination of uncertainty of measurement, refer to IEC 62301:2011,

Annex D.
5.1.7 Luminance measuring device

When directed to measure display luminance a luminance measuring device (LMD), which

may be of either the contact or non-contact type, shall be used. The LMD shall have an

---------------------- Page: 12 ----------------------
