Overview of IEC 62087 Test Standard

iec 62087 is an international standard formulated by the International Electrotechnical Commission (IEC) regarding the measurement methods for power consumption of audio, video and related equipment, with its full title: IEC 62087: Methods of measurement for the power consumption of audio, video, and related equipment.

This standard is mainly used to standardize the energy consumption test methods for consumer electronic devices such as televisions, monitors, audio equipment, and set-top boxes, and serves as an important basis for energy efficiency certifications (e.g., Energy Star, EU ErP, China Energy Label).

Standard Composition

IEC 62087 is a series of standards, mainly consisting of the following parts:

Core Test Content

(1) Test Conditions

A. Environmental Requirements: Temperature (23±5°C), humidity (45%~75%), stable power supply (voltage fluctuation ≤±2%).

B. Equipment Status:

①　Standby: The equipment is connected to the power supply but does not perform main functions.

②　Off Mode: The equipment is completely turned off but still plugged in.

③　Active Mode: Playing standard test content (e.g., dynamic videos, static images).

(2) Test Methods

①　Dynamic Video Test (for televisions, monitors): Playing standard dynamic video sequences (e.g., test clips specified by IEC 62087).

②　Static Image Test (for monitors, digital photo frames): Displaying specific static images (e.g., full white, full black, 50% gray scale).

③　Audio Test (for audio equipment, power amplifiers): Playing standard audio signals (e.g., 1 kHz sine wave).

(3) Key Indicators

①　Average Power Consumption (W): Typical energy consumption in Active Mode.

②　Standby Power Consumption (W): Compliant with international regulations (e.g., EU ErP requires standby power ≤ 0.5 W).

③　Energy Efficiency Index (EEI): Used for energy efficiency classification (e.g., EU Energy Label).

Relationship with Other Energy Efficiency Standards

Test Equipment and Procedures

(1) Required Equipment

①　Power analyzer (accuracy ≥ 0.5%).

②　Standard test signal source (e.g., IEC 62087 test video/audio files).

③　Environmental monitoring equipment (hygrothermograph, regulated power supply).

(2) Test Procedures

①　Preheat the equipment: Turn on and run for at least 30 minutes until a stable state is reached.

②　Measure standby/off-mode power consumption: Record the average power within 10 minutes.

③　Measure active-mode power consumption: Play standard test content and record data for at least 10 minutes.

④　Calculate energy efficiency values: Compute energy efficiency grades (e.g., EEI) according to standard formulas.

Typical Applications

①　Televisions/Monitors: For energy efficiency label certification (e.g., EU A+ grade televisions).

②　Audio Equipment/Power Amplifiers: Evaluate whether standby power consumption complies with ErP regulations.

③　Set-top Boxes/Routers: Meet Energy Star or COC Tier 2 standards.

Precautions

(1) Latest Version: IEC 62087:2023 (4th edition) is the latest international standard; some countries may still adopt older versions (e.g., IEC 62087:2015).

(2) Regional Differences:

①　EU: Must comply with EN 62087 (equivalent to the IEC standard).

②　U.S.: Energy Star references the IEC 62087 method.

③　China: GB/T 26256-2021 (equivalent to IEC 62087:2015).

(3) Software Impact: The firmware version of smart televisions/devices may affect power consumption; the software version must be fixed during testing.
