What are IEC standards?

2025-08-01

What are IEC standards?

The International Electrotechnical Commission (IEC) develops and publishes IEC standards, which are based on a global consensus. IEC standards cover electrical safety, labeling, performance, test methods, and other guidelines for electrical and electronic products.

Product Examples

Consumer electronics

Household products

Batteries

Semiconductors

Nanotechnology

Solar energy products

Fibre optics

IEC Members

National committees make up the IEC's membership, with each committee representing the electrotechnical interests of its home country. These nations include the US, the UK, the EU, and other nations.

IEC standards are voluntary, but technical professionals worldwide continue to utilize them, and national technical bodies and lawmakers frequently approve them. The European Committee for Electrotechnical Standardization (CENELEC), for instance, frequently incorporates IEC standards while creating new EN standards, either whole or in part.

IEC standards examples

Several technical committees (TCs) within the IEC are tasked with creating standards for various product categories. A technical committee may form subcommittees, each of which may concentrate on a particular topic and have specialized knowledge.

A few examples of standards that apply to consumer goods are shown below.

CommitteeTitleStandard Example
TC 34LightingIEC 61547 – Equipment for general lighting purposes – EMC immunity requirements
SC 28Office EquipmentISO/IEC 10561 – Information technology — Office equipment — Printing devices — Method for measuring throughput — Class 1 and Class 2 printers
TA 6Storage media, storage data structures, storage systems and equipmentIEC 62702-1-1 ED2 – Audio archive system – Part 1-1: DVD disk and data migration for long term audio data storage
TA 5Cable networks for television signals, sound signals and interactive servicesIEC 60728-11 ED5 – Cable networks for television signals, sound signals and interactive services – Part 11: Safety
TC 79Alarm and electronic security systemsIEC 62676-2-11 ED1 – Alarm systems – Video Surveillance Systems (VSS) for use in security applications – Part 2-11: Interop profiles for VMS- and cloud VSaaS-systems for safe-cities and law-enforcement
TC 62Electrical equipment in medical practiceIEC 60050-880 ED1 – International Electrotechnical Vocabulary (IEV) – Part 880: Electrical equipment, electrical systems and software used in healthcare
SC 61DAppliances for air-conditioning for household and similar purposesIEC 60335-2-40 ED7 – Household and similar electrical appliances – Safety – Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers
SC 59LSmall household appliancesIEC 63399 ED1 – Household and similar use electrical rice cookers – Methods for measuring the performance
SC 59FSurface cleaning appliancesIEC/ASTM 62885-7/AMD1 ED1 – Amendment 1 – Surface cleaning appliances – Part 7: Dry-cleaning robots for household or similar use – Methods for measuring the performance
SC 23BPlugs, socket-outlets and switchesIEC 60884-1 ED4 – Plugs and socket-outlets for household and similar purposes – Part 1: General requirements

Is IEC standards compliance mandatory?

According to the IEC, its standards are voluntary. However, given the fact that IEC standards are based on global consensus, importers and manufacturers can still benefit from complying with these standards – especially when no other relevant standards exist for their products. This could be the case if an IEC standard is published before a corresponding EN or UL standard is published.

Also, countries might decide to incorporate IEC standards into their own national standards.

For example, IEC standards make up a majority of the European Union’s EN standards for electrical and electronics products such as

Kettles

Ceiling lights

Office printers

Heartbeat monitors

EN standards might in turn be harmonized under a specific directive or regulation and – though also voluntary – provide the presumption that tested products conform with relevant technical requirements under the directive or regulation.

Example

The following standard is harmonized under the Low Voltage Directive:

EN IEC 60335-2-43 – Household and similar electrical appliances – Safety – Part 2-43: Particular requirements for clothes dryers and towel rails

Are IEC standards recognized in the European Union?

The Frankfurt Agreement governs cooperation between the CENELEC and the IEC. IEC standards are not adopted by default; rather, the CENELEC authorizes the EU's adoption of the standards on an individual basis.

Nevertheless, IEC standards serve as the foundation for around 80% of EU standards relating to electronics and electrical products.
