IEC 62087-7-2018 PDF

Full title and description

Audio, video and related equipment - Methods of measurement for power consumption - Part 7: Computer monitors. This International Standard specifies methods to determine the power consumption of mains‑powered computer monitors (including CRT, LCD, PDP and OLED technologies), covers monitors with touch functionality, defines relevant operating modes (on, partial on, standby, off), and sets measurement conditions, test patterns and procedures to obtain repeatable power and luminance measurements for conformity testing and energy reporting.

Abstract

IEC 62087-7:2018 provides standardized procedures for measuring the electrical power consumption and related parameters of computer monitors when powered from the mains. It defines test conditions (power supply, ambient and illuminance), required measuring instruments (power analyzers, luminance meters), signal generation and test patterns (static, dynamic and web‑based video), handling of automatic brightness control (ABC), and methods to determine on‑mode, partial‑on, standby (active/passive) and off‑mode power, including power‑factor measurement and reporting requirements. The procedures are intended to reflect normal use and to support manufacturer declarations, energy labelling and regulatory or voluntary efficiency programs.

Scope

This part of IEC 62087 applies to mains‑powered computer monitors that do not include a TV tuner and are intended to display video signals from a computer. It covers a wide range of display technologies (CRT, LCD, PDP, OLED) and input types (digital interfaces such as DisplayPort, HDMI, DVI, or analogue VGA). The document excludes battery‑powered monitors and monitors that are primarily networked or wirelessly connected; it also excludes specialized professional/medical/publishing monitors intended for niche professional applications. The scope includes definition of operating modes and test procedures for static and dynamic content to represent normal user operation.

Key topics and requirements

• Definition of operating modes and functions relevant to power measurement (on, partial on, standby‑passive, standby‑active, off).
• Measurement conditions: mains voltage and frequency, ambient temperature, ambient illuminance and luminance reference levels for specified resolutions.
• Test equipment and accuracy requirements: power measuring instrument, luminance and illuminance meters, signal generation equipment and interface configurations.
• Procedures for on‑mode power measurement using static patterns, dynamic video and web‑based video; stabilization and measurement sequences.
• Handling of automatic brightness control (ABC): methods to disable or characterize ABC and prescribed ABC test levels where applicable.
• Partial‑on and standby measurement procedures, including network/availability considerations and off‑mode measurement methods.
• Power‑factor determination and reporting requirements; test report content and measurement uncertainty considerations.
• Recommended order of test activities, setup, cool‑down and repeatability practices to ensure comparable results.

Typical use and users

Primary users include display and monitor manufacturers, independent test laboratories, regulatory authorities and compliance bodies, energy‑efficiency programme administrators (e.g., labelling and voluntary schemes), procurement teams, and product designers/engineers who need repeatable methods to characterise power consumption for certification, product specification and eco‑design. The standard is used to produce manufacturer declarations, to support conformity assessment and to provide test data for energy labelling or regulatory compliance.

Related standards

Related publications commonly used alongside IEC 62087-7 include other parts of the IEC 62087 series (general methods for audio/video equipment), IEC 62301 (measurement of standby and low‑power modes), regional/adopted versions such as EN IEC 62087-7 (European adoption), and various test procedures or regulations used by energy‑efficiency programmes (for example ENERGY STAR test methods and regional ecodesign requirements for displays). Test labs often reference IEC 62301 when performing low‑power (standby/off) measurements.
