Electrotechnical Standards

NSAI Electrotechnical Standards Programme

The NSAI Electrotechnical Standard Programme covers all areas of electro-technology including power generation (including all renewable energy sources), transmission, distribution, smart grids, batteries, home appliances, office and medical equipment, public and private transportation, semiconductors, fibre optics, nanotechnology, multimedia, information technology, and more. It also addresses safety, electromagnetic compatibility, performance and environmental issues.

NSAI Standards is the Irish member organization of the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (CENELEC) and the standards output of these bodies provides the primary source for Irish Standards in the electrical area.

International Electrotechnical Commission (IEC)

The IEC is the world’s leading organization that prepares and publishes globally relevant International Standards for all electrical and electronic devices and systems. It brings together 171 countries (84 Members and 87 Affiliate Countries), representing 97% of the world population and 96% of world energy generation. Close to 20 000 experts cooperate on the global IEC platform and many more in each member country.

The IEC provides a well proven collaborative environment for companies, industries and governments to convene, discuss and agree the electro-technical standards they require for today's, and tomorrow's, global economy.
All IEC International Standards are fully consensus-based and represent the needs of key stakeholders of every nation participating in IEC work. Every member country, no matter how large or small, has one vote and a say in what goes into an IEC International Standard.
European Committee for Electrotechnical Standardization (CENELEC)

CENELEC is a European Standards Organization responsible for standardization in the electro-technical engineering field. CENELEC prepares voluntary standards, mainly European Standards (EN), which help facilitate trade between countries, create new markets, cut compliance costs and support the development of a Single European Market. 

CENELEC creates market access at European level but also at international level, adopting International Standards wherever possible, through its close collaboration with the IEC under the Frankfurt Agreement.

The CENELEC Internal Regulations require that CENELEC European Standards are implemented at national level by being given the status of a national standard and by withdrawal of any conflicting national standard. The fact that European Standards must be transposed into a national standard in all member countries guarantees that a manufacturer has easier access to the market of all these European countries when applying European Standards. This applies whether the manufacturer is based in the CENELEC territory or not.
NSAI Electro Technical Committee (ETC)

In order to advise NSAI on technical and policy matters concerning Ireland’s membership of the IEC and CENELEC, the formulation of Irish Standards and the establishment and maintenance of the infrastructure of NSAI national mirror Technical Committees, NSAI has established a consultative Electro Technical Committee (ETC). The membership of the committee is composed of key stakeholders/collective bodies that provide an authoritative and representative voice or policy role in the electrical sector.
NSAI ETC Technical Committees (TC)

To deliver the technical standardization work, NSAI maintains a network of Technical Committees (TC) covering many areas of electro-technology. These committees generally mirror one or more IEC and CENELEC committee. NSAI technical committee members contribute their knowledge and expertise on a voluntary basis and join their European and International counterparts in developing a worldwide system of standards. NSAI staff members provide the Secretariat for many NSAI ETC Technical Committees.

Since 2017, NSAI has assumed direct responsibility for the maintenance and development of the national system of electrical installation standards. This work is focused primarily in NSAI ETC TC2, where the revision of ETCI Publication ET101:2008 has commenced.
