Sustainable management of waste electrical and electronic equipment (e-waste)
Käsitlusala: This document specifies requirements and provides guidance for the sustainable management of waste electrical and electronic equipment (e-waste) for all process steps, from collection to returning recovered products, components, materials or energy to the value chain. It includes traceability, monitoring and evaluation of the e-waste flow, recovery rate and recovery quality.
This document is intended for use by an organization involved in e-waste management seeking to manage its responsibilities in a systematic manner.
The requirements set by this document will help an organization to achieve sustainability outcomes within the context of e-waste management, including:
– enhancement of organizations' performance in relation to quality, environment and occupational health and safety;
– fulfilment of compliance obligations.
This document is applicable to any organization, regardless of its size, type and nature.
This document applies to the environmental, health and safety, and quality aspects of e-waste management activities that the organization determines it can either control or influence, from a lifecycle perspective.
NOTE 1 Social aspects – e.g. employment creation, conflict minerals, employment conditions – are not addressed directly but indirectly through the benefits of sustainable management of e-waste.
NOTE 2 Additional local requirements or regulations can apply.
This document is a basic environment horizontal publication focusing on essential requirements and is primarily intended for use by committees in the preparation of publications within the area of environment in accordance with the principles laid down in IEC Guide 123. Wherever applicable, it is the responsibility of committees to make use of environment basic publications in the preparation of their environment group and product publications. Committees can apply this document directly to products when they do not develop a product publication in the area of environment.

High-voltage switchgear and controlgear - Part 201: AC solid-insulation enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV
Käsitlusala: IEC 62271-201:2026 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 62271-201:2026 EXV includes the content of the references made to IEC 62271-1:2017+AMD1:2021.
IEC 62271-201:2026 is applicable to prefabricated solid-insulation enclosed switchgear and controlgear assemblies designed for:
– alternating current;
– rated voltages above 1 kV and up to and including 52 kV;
– service frequencies up to and including 60 Hz;
– indoor installation;
– areas limited to authorized personnel.
The assembly can include either air-insulated or fluid-filled compartments, or both.
For components installed in a solid-insulation enclosed switchgear and controlgear, this document supplements or even replaces in some cases, the requirements as stated by the individual product standards. The list of components which can be inside the solid-insulation enclosed switchgear and controlgear is not limited to the ones explicitly cited in this document. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) aligned with the third edition of IEC 62271-200 published in 2021 and its Amendment 1 published in 2024, for structure, definitions, classifications, ratings and testing procedures, where appropriate;
b) clause numbering aligned with IEC 62271-1:2017, including the adoption of the subclause names of Clause 3;
c) in Clause 3 specific terms and definitions are added for "in service", "normal operating condition" and "normal use";
d) earthing circuit is more precisely described, including ratings and test requirements;
e) number of mechanical tests on interlocks is reduced for type testing;
f) forces to apply during type testing are better prescribed (refer to 7.102);
g) resistance measuring on main circuit is only needed before continuous current tests (as reference for routine tests) and not anymore needed after this continuous current test. Rationale for this deletion is that this measured resistance does not mean anything; as the temperature rise test was just finished, a new temperature rise test will not give new information;
h) IEC 62271-100:2021 has been taken into account in 7.101.2;
i) IEC 62271-107:2019 and IEC IEEE 62271-37-013:2021 are also considered in 7.101.2;
j) LSC category is more precisely described, including an explaining flowchart (Annex G);
k) examples not covered by the IAC test are transferred from Clause 6 to 9.103;
l) the term "assembly" is defined in Clause 3 and used as synonym for "solid-insulation enclosed switchgear and controlgear" in this document;
m) "metallic" is replaced by "metal" where applicable;
n) a 1 s rule was introduced for Criterion 4 during IAC tests regarding hot gases versus glowing particles as cause of ignition;
o) internal arc tests for switchgear with protrusions are more precisely described in Annex A;
p) partitions accessible in normal use are now PA, PB1 or PB2 instead of PI which has been removed (refer to 6.103.3)

Transformers and inductors for use in electronic and telecommunication equipment - Part 389: Measuring methods and test procedures
Käsitlusala: IEC/IEEE 61007-389:2026 describes a number of tests for use in determining the significant parameters and performance characteristics of transformers and inductors for use in electronics and telecommunication equipment. These test methods are designed primarily for transformers and inductors used in all types of electronics applications that can be involved in any specification for such components. Even though these tests could be applied supplementally for other types of transformers, such as those with larger power ratings used in the utility power industry, the tests discussed in this document are not intended to replace the tests in standards for those other transformers.
Some of the tests described are intended for qualifying a product for a specific application, while others are test practices used for manufacturing and customer acceptance testing. The test methods described here include those parameters most commonly used in the electronics transformer and inductor industry: electric strength, resistance, power loss, inductance, impedance, balance, transformation ratio and many others used less frequently.
This first edition of IEC/IEEE 61007-389 cancels and replaces IEC 61007:2020 and IEEE 389:2020, which has been technically revised.

Transformers and inductors for use in electronic and telecommunication equipment - Measuring methods and test procedures
Käsitlusala: IEC 61007:2020 describes a number of tests for use in determining the significant parameters and performance characteristics of transformers and inductors for use in electronics and telecommunication equipment. These test methods are designed primarily for transformers and inductors used in all types of electronics applications that can be involved in any specification for such components. Even though these tests can be useful to the other types of transformers used in power distribution applications in utilities, industry, and others, the tests discussed in this document can supplement or complement the tests but are not intended to replace the tests in standards for transformers. Some of the tests described are intended for qualifying a product for a specific application, while others are test practices used for manufacturing and customer acceptance testing. The test methods described here include those parameters most commonly used in the electronics transformer and inductor industry: electric strength, resistance, power loss, inductance, impedance, balance, transformation ratio and many others used less frequently.
