EVS-EN IEC 62301:2026

This document specifies methods of measurement of electrical power in standby mode(s) and other non-active modes (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 63474:2026.
This document applies to electronic and electrical equipment powered by:
– low voltage AC power (LV ≤ 1 000 V AC), or
– low voltage DC power (LV ≤ 1 500 V DC) that is ripple-free, measured between conductors or between a conductor and earth, or
– extra low voltage AC power (ELV ≤ 50 V AC), or
– extra low voltage DC power (ELV ≤ 120 V DC) that is ripple-free, measured between conductors or between a conductor and earth, or
– an external power supply that provides low voltage or extra low voltage AC or DC power, or – a separate source of extra low voltage DC power, or
– an internal main battery.
Conditions that are out of scope:
– active modes (primary function)
– networked standby mode (which is covered by IEC 63474:2026)
– conditions where main batteries are being charged other than in 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 with electrical components.
NOTE 1 The measurement of power, energy use and performance of products during their intended use (when performing their primary functions) are generally specified in product standards and are not covered by this document.
Where this document is referenced by performance standards or procedures, these are to define and name the relevant non-active mode to which this test procedure is applied.
NOTE 2 Non-active modes for lighting equipment and the measurement of power is specified in IEC 63103 [2].
NOTE 3 Edge equipment can also include auxiliary batteries.
Annex A shows the conceptual framework of power modes and functions.
This document does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy use.
This group energy efficiency publication is primarily intended to be used as an energy efficiency standard for the products mentioned in the scope, but is also intended to be used by TCs in the preparation of publications for products which are included in the boundary mentioned in the scope of this document.
