M/450 - Measurement of electric power
Mandate to CEN, CENELEC and ETSI for Standardisation in the field of measurements of no-load condition electric power consumption and average active efficiency of external power supplies
Mandate M/450 requests CEN, CENELEC, and ETSI to develop European standards related to the measurement of electric power. Specifically, it focuses on standardising methods for measuring no-load condition electric power consumption and determining the average active efficiency of external power supplies. The objective is to support regulatory frameworks and promote energy efficiency by providing consistent and reliable measurement standards across the EU. These standards will facilitate market surveillance, improve environmental performance, and enhance consumer protection regarding energy consumption of external power supplies.
Purpose
The mandate M/450 aims to establish standardisation in measuring no-load condition electric power consumption and the average active efficiency of external power supplies. This focuses on defining consistent methods to assess the energy efficiency and power usage of these devices when not under load.
Standardisation request
CEN, CENELEC, and ETSI are requested to develop standards covering measurement procedures for the electric power consumed by external power supplies in no-load conditions, as well as measurement methods to determine their average active efficiency. This includes harmonising measurement techniques to ensure comparability and compliance with relevant energy efficiency requirements.
Expected deliverables
The expected deliverables from this mandate include:
- Harmonised standards specifying procedures for measuring no-load electric power consumption of external power supplies.
- Standards for determining the average active efficiency of external power supplies under operating conditions.
- Documentation and testing protocols that facilitate accurate and reproducible measurements to support regulatory and market surveillance activities related to energy efficiency.
Context
External power supplies are commonly used in a wide range of electrical and electronic equipment. Their energy consumption, particularly in no-load conditions, contributes to overall energy usage and environmental impact. Standardisation in this field supports the EU’s energy efficiency and sustainability objectives by enabling consistent testing and certification, facilitating compliance with energy-related product regulations.
This mandate covers the standardisation of measuring no-load condition electric power consumption and the average active efficiency of external power supplies used in electrical and electronic equipment. It focuses on ensuring consistent and reliable measurement methods for energy efficiency evaluation of external power supplies across relevant sectors.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/450 is a European Standardization Mandate titled "Mandate to CEN, CENELEC and ETSI for Standardisation in the field of measurements of no-load condition electric power consumption and average active efficiency of external power supplies". Mandate to CEN, CENELEC and ETSI for Standardisation in the field of measurements of no-load condition electric power consumption and average active efficiency of external power supplies There are 0 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
