CENELEC is the European Committee for Electrotechnical Standardization.
The members of CENELEC are the National Electrotechnical Committees of the member states of the European Union and EFTA.
The Technical Committees (TC) and Sub-Committees (SC) are responsible for the preparation of the European Standards (EN).
New standardization initiatives originating in Europe are offered to the International Electrotechnical Commission IEC with the request that they will be undertaken at international level. Only if IEC does not want to undertake the work, or if it cannot meet CENELEC target dates, does the work continue at European level.

Exothermic reaction of a combustible substance with an oxidizer (usually oxygen), usually accompanied by flames, and/or glowing and/or emission of smoke.

The 2013 Construction Product Regulation (CPR) aims at giving reliable information on the performance of construction products including legal responsibilities for manufacturers, importers and suppliers.
Harmonized technical specifications (i.e. EN standards) provide a “common technical language” with uniform assessment methods for establishing the performance of construction products. This common technical language has to be used by:

• Manufacturers when declaring their products performance (DoP - Declaration of Performance) for intended end-use
• Member States authorities when specifying requirements
• Users (constructors, architects, technicians) when selecting products most adequate for their intended use in construction works.

A European Standard (EN) is a document that has been ratified by one of the three European Standardization Organizations (ESOs), CEN, CENELEC or ETSI.
An EN “carries with it the obligation to be implemented at national level by being given the status of a national standard and by withdrawal of any conflicting national standard".
It automatically becomes a national standard in each of the 34 CEN-CENELEC member countries.

ETSI (the European Telecommunications Standards Institute) works on standards for Information and Communications Technologies (ICT), addressing fixed, mobile, radio, broadcast and Internet technologies.
ETSI is a not-for-profit organization with more than 800 member organizations from 65 countries and five continents.
