prEN IEC 62301:2025

This document specifies methods of measurement of electrical power in standby mode and other non-active mode (such as off mode) and the reporting of the results.
The measurement of power and energy use in networked standby mode, is covered by IEC 63474.
This document applies to electronic and electrical equipment powered by:
– low voltage mains AC power (𝐿𝑉 ≤ 1000 𝑉 𝐴𝐶), or
– an external power supply that provides low voltage (𝐿𝑉 ≤ 1000 𝑉) or extra low voltage (𝐸𝐿𝑉 ≤ 50 𝑉) AC or DC power, or
– a separate source of extra low voltage DC power (𝐸𝐿𝑉 ≤ 50 𝑉 𝐷𝐶), or
– an internal main battery.
Conditions that are out of scope:
– active mode (primary function)
– networked standby mode (which is covered by IEC 63474)
– conditions where main batteries are being charged other than maintenance mode
– disconnected condition of the equipment.
This document applies to the following product groups where a non-active mode is present:
– household appliances, electrical and electronic equipment such as information technology equipment, audio, video and multimedia systems and equipment,
– gas burning equipment.
NOTE 1 The measurement of power, energy use and performance of products during their intended use (when performing their primary function) are generally specified in product standards and are not covered by this document.
NOTE 2 Where this document is referenced by performance standards or procedures, these should define and name the relevant non-active mode to which this test procedure is applied.
NOTE 3 Non-active modes for lighting equipment and the measurement of power is specified in IEC 63103 [1].
NOTE 4 Edge equipment can also include auxiliary battery.
This standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy use.
This document has the status of a horizontal publication in accordance with IEC Guide 108.
