Electrical engineering standards play a key role in ensuring electrical safety, regulatory compliance and reliable system performance. EN and IEC standards define requirements for electrical installations, switchgear, EMC, testing equipment and low-voltage systems used across industries.
As standards are regularly updated, engineers, manufacturers and installers need efficient ways to stay informed about new and revised electrical engineering standards in 2026.
Electrical standards are continuously evolving
Standards in the electrical field are continuously evolving. Staying informed is essential for designers, manufacturers, installers, inspectors and quality managers.
New ISO and IEC standards are regularly published at the international level. In addition, European standards are developed, some of which may be harmonised:
In our e-shop, you can verify whether a standard is harmonised by checking the “Directives and regulations” section within the general information for each standard.
Tracking updates across a wide range of electrical disciplines can be time-consuming. To simplify this, we offer a free Information service that delivers updates directly to your e-mail.
It allows you to receive targeted updates on the standards most relevant to your work in the electrical engineering field.
How to stay informed about EN and IEC electrical standards
Register as a user or log in and subscribe to the Information service. Updates are sent only for selected ICS fields (at least one must be selected).
Electrical engineering standards are primarily included in ICS 29 – Electrical engineering.
By selecting this field, you will receive updates on new and revised standards across key areas such as electrical materials (including magnetic, insulating, and semiconducting materials), cables and wiring systems, and components and accessories.
You will also stay informed on developments in switchgear and controlgear, lighting equipment, rotating machinery, transformers, power supply systems, batteries, and power transmission and distribution networks.
We will send updates twice per month via e-mail, usually within the first and third working week of the month. You can manage your Information service anytime through your user account, including adding or removing fields.
You can also use other free tools to monitor specific standards and receive updates on changes in IEC and EN standards.
Key electrical field standards series
IEC 60364 series – establishes requirements for low-voltage electrical installations. The series is intended to harmonise national wiring standards within an IEC framework and is published in the Europe by CENELEC as "HD 60364".
IEC 61010 series – defines safety requirements for electrical equipment used for measurement, control and laboratory applications. Many parts of this series have been harmonised and published as EN standards.
IEC 60204 series – specifies safety requirements for electrical equipment of machinery. All parts in the IEC 60204 series are published under the general title Safety of machinery – Electrical equipment of machines.
IEC 61557 series – aims to stipulate common principles for measuring and monitoring equipment for testing electrical safety and measuring performances in systems with nominal voltages up to 1 000 V AC and 1 500 V DC.
IEC 62305 series – provides guidelines for protection against lightning, including risk management and structural protection. Protection measures considered in the IEC 62305 series have been proven to be effective in risk reduction.
IEC 61439 series – defines requirements for low-voltage switchgear and controlgear assemblies. List of all parts of the IEC 61439 series is under the general title Low-voltage switchgear and controlgear assemblies.
FAQ about electrical engineering standards
What are electrical engineering standards?

IEC standards are regularly revised to reflect technological developments, safety requirements and regulatory changes.
What are harmonised electrical standards?
Harmonised standards support compliance with EU directives such as the Low Voltage Directive and EMC Directive.
How can I stay updated on IEC standards?
You can subscribe to an information service that sends updates about new and revised standards in selected ICS fields.
