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/244 is a European Standardization Mandate titled "Efficiency of general purpose low-voltage 3 phase induction electric motors". Efficiency of general purpose low-voltage 3 phase induction electric motors There are 6 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.
IEC 60034-2-1:2024 is available as IEC 60034-2-1:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60034-2-1:2024 is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses. This document applies to DC machines and to AC synchronous and induction machines of all sizes within the scope of IEC 60034-1 rated for mains operation. These methods may be applied to other types of machines such as rotary converters, AC commutator motors and single-phase induction motors. This third edition cancels and replaces the second edition of IEC 60034-2-1 published in 2014. This edition includes the following significant technical changes with respect to the previous edition:
- Harmonization of layout and requirements with IEC 60034-2-2 and IEC 60034-2-3.

IEC 60034-2-1:2014(B) is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses. This standard applies to d.c. machines and to a.c. synchronous and induction machines of all sizes within the scope of IEC 60034-1. This new edition includes the following significant technical changes with respect to the previous edition: grouping of the test methods into preferred methods and methods for field or routine testing; addition of the details of the requirements regarding instrumentation; addition of the description of tests required for a specific method in the same sequence as requested for the performance of the test.
