article 8 of Act 21/1992 for Industry, defines a standard as "The technical specification of repeated or continuous application, the compliance of which is not mandatory, established with the participation of all interested parties, which is approved by a recognised body, at a national or international level, for its regulatory activity."
The Spanish Association for Standardization,
UNE, is a private and independent non-profit association and is recognised in Spain as the national standardization body, in line with the Regulation on Infrastructure for Industrial Quality and Safety, approved by
Royal Decree 2200/1995 and in
Regulation (EU) No. 1025/2012 on European Standardization.
UNE is the Spanish standardisation body in the European Committee for Standardisation,CENin the European Committee for Electrotechnical Standardization,
CENELEC, in the European Telecommunications Standards Institute,
ETSIin the Pan-American Standards Commission, COPANT, as well as in the International Organization for Standardization,
ISO and in the International Electrotechnical Commission,

CEN and CENELEC develop, with the participation of all the national standardization organisations that constitute them, such as UNE, the European EN standards. These must be adopted as UNE standards by putting the letters UNE before the code of the European standard.
In this way, the European standard EN 1234:2019 will be added to the Spanish national catalogue as UNE-EN 1234:2019.
Similarly, ISO and IEC develop them with the national bodies concerned and finally publish their international standards. These can also be adopted at a European level or directly at a national level. In the first case, the standard ISO 123:2019, for example, would be adopted as UNE-EN ISO 123:2019.
If this international standard is not adopted as a European standard, but if it is decided to adopt it at a national level in UNE, the corresponding code would be UNE-ISO 123:2019.
UNE standards are voluntary, but by their reference in legislative provisions, the Regulatory Authorities can decide if their content, in whole or in part, becomes mandatory. In this regard, it should be noted that 12% of the catalogue of UNE standards is cited in the national legislation.
For the sectors that draw up technical standards, legislation based on such standards will contribute to reducing the costs associated with compliance, because they have a prior understanding of the requirements and can gradually become adapted to them.
The proposal to develop a standard can originate from any entity, whether public, private, the UNE or its Governing Bodies, International or European standardisation bodies at the proposal of a member country.
UNE is the body responsible for managing new standardization initiatives, establishing the appropriate mechanisms for their dissemination, study and implemention.
To perform this function, UNE carries out several actions aimed at gauging the opinion of the various stakeholders, in order to establish the national stance for each proposal and to implement suitable mechanisms to influence and track the developments that achieve sufficient support.
If you would like to give your opinion, receive information or participate, please contact
firstname.lastname@example.org. If you wish to propose a new standardisation development, you can use this
form to provide us with the information requested so that we can know and assess your proposal.
UNE standards are drawn up and published by the
Spanish Association for Standardization (UNE), designated by Order of the Ministry of Industry and Energy of 26 February 1986, as a national standardization body and, therefore, the Association must be contacted to carry out
any enquiries on UNE standards.
Furthermore, through this organisation, you can consult technical standards of other international standardization organisations (ISO, CEN, CENELEC, etc.)
On the UNE website you have access to a search engine that will allow you to find information on projects under development, as well as on the standards included in the catalogue.
In order to facilitate access to standards for all organisations, and in particular SMEs, UNE offers stakeholders various mechanisms to access the content of standards and standard projects:
On the website of
AENOR, you can access the purchase process.
Additionally, standards can be acquired with favourable terms through UNE at various sector associations, professional associations and other types of collaborating entities. The prices of these are subject to agreement with the administration.
Technical standards are developed by the national standardization body (UNE) through the Technical Standarization Committee in which all parties concerned in their drafting are voluntarily present.
AENOR facilitates their development by collaborating with companies, public administrations, research organisations and social agents, with the government participating in part of standardisation process and the dissemination of the corresponding results.
The process of drawing up UNE standard is subject to a series of phases thus ensuring that the final document is the result of consensus, and that any person, even if they do not belong to the body drawing up the standard, can voice their opinions or comments.
Prior to their approval, the Official State Bulletin publishes the monthly list of UNE projects that are in Public Consultation stage, during which time any interested person or company can submit observations. You can access the UNE standard projects via public consultation and comment on them through the
UNE Project Review System.
Observations should be communicated to UNE. Once the comments received in this phase have been analysed, the committee will write up the final text, which will finally be approved and published as a UNE standard.
If you are interested in participating directly in the elaboration of a standard in any of the Technical Standardisation Committees, please contact
Similarly, you can participate indirectly by reviewing and issuing comments to draft standards when they are in the public information phase.
Participation in standardisation activities allows us to:
The main stage in the development of a standard, to guarantee due transparency, is the Public Information (PI) stage. During this stage, any citizen can make comments relating to any ongoing project.
If you wish to find out which projects are in the PI stage and contribute your comments, you can do so through the
UNE Project Review System. All comments received will be considered by the committee in charge of drafting the standard.
You can also subscribe to any areas of interest that you would like to be kept informed every time a new project enters the public information stage, letting you keep up to date with the latest information at all times.
