Full title and description

St IEC 62301-2011 — Household electrical appliances — Measurement of standby power. This standard specifies methods for measuring the electrical power consumption of household and similar electrical appliances in standby and off modes, including definitions, test conditions, measurement procedures and reporting requirements to ensure repeatable, comparable and accurate determination of low power consumption.

Abstract

IEC 62301:2011 provides a standardized procedure to measure low active power (typically in the milliwatt range) drawn by household appliances when they are not performing their primary function (standby or off modes). The standard defines test setup, environmental and electrical conditions, stabilization and averaging times, instrument accuracy, and methods for expressing and reporting measured values and uncertainties. It is intended to support regulatory programs, energy labeling, product development and conformity testing by enabling consistent measurement of standby power.

Scope

The standard applies to electrical measurements of power consumed by household and similar electrical appliances in standby mode and off mode. It covers definitions of operating modes, measurement equipment and procedures, environmental and supply voltage conditions, stabilization and measurement periods, data processing and presentation of results including uncertainty estimation. It is not intended for general appliance energy consumption during active operation beyond standby/off conditions, nor for non-electrical energy sources.

Key topics and requirements

• Definitions of standby, off-mode and other low-power states for household appliances.
• Requirements for the electrical supply conditions (voltage, frequency, harmonics) during testing.
• Specification of measurement instruments: resolution, accuracy, input characteristics and instrument calibration.
• Test set-up and environmental conditions (temperature, humidity) to ensure repeatability.
• Stabilization times and recommended averaging and measurement intervals to capture low-level power behavior.
• Procedures for recording transient behaviors, warm-up effects and periodic functions that affect standby power.
• Methods for calculating and reporting measured power values, including expression of measurement uncertainty.
• Guidance on test sequencing, sample selection and reporting format for compliance and comparison.

Typical use and users

Regulatory agencies, conformity assessment bodies and test laboratories use this standard to verify compliance with standby power limits in legislation and energy labelling programs. Manufacturers and R&D engineers use it during product design, validation and quality control to minimize standby losses. Energy efficiency consultants and certification schemes use the measurement procedures to benchmark products and compile databases.

Related standards

Commonly used alongside standards and publications that define energy performance and measurement practices, including IEC 62087 for audio/video equipment, IEC 60664 and IEC 61000 series for EMC and electrical supply compatibility, and regional/regulatory documents that set maximum standby power limits or labeling requirements. It also complements test standards for specific appliance categories that reference standby measurement methods.
