As a compliance assessor, AENOR is a leading product certification entity. The AENOR N Mark now features on more than 100,000 certified products in more than 40 countries and is one of the world's five most popular quality marks.

The AENOR N Mark is a voluntary mark that enables companies to demonstrate that their products comply with certain requirements set forth in a UNE, EN, ISO standard or technical specification. This proof of compliance, based on AENOR's rigorous monitoring of manufacturing processes and final product tests, will enable holders of the Mark to place products of a high quality and standard on the market, which will instil confidence in the users of certified products.

Royal Decree 314/2006, of 17 March, approving the Technical Building Code (CTE), is the regulatory framework that establishes the requirements that must be met by buildings in terms of basic safety and habitability aspects, established in Act 38/1999 of 5 November, on Building Standards (LOE).

The AENOR N Mark is recognised by the Ministry of Public Works and Transport as a standard of quality of the CTE. This recognition means that the Administration is sufficiently confident in the products certified under the AENOR N Mark considering that the use of these products in buildings contributes to compliance with the basic requirements set forth in legislation. For this reason, use of AENOR N Mark products benefits all agents involved in constructing a building.

This way, the AENOR N Mark can provide the following advantages:

The certification process comprises the following stages:

​APPLICATION

The AENOR Mark is voluntary. Companies that want AENOR to certify their product must submit their application in accordance with the formats established by AENOR. This application must include information about the company and the characteristics of the products for which certification is sought.

Once AENOR technical staff have analysed the documents, compliance assessment activities will be performed in order to verify that the products comply with the applicable standards:

AUDIT/INSPECTION

An annual visit is made to the production centre, during which:

• a) the quality management system is audited in accordance with the UNE-EN ISO 9001 requirements that are directly related to the production process.
• b) The manufacturer's manufacturing process and production controls are inspected to ensure the product complies with the requirements of the standard.
• c) Samples are taken and sent to an accredited laboratory, which performs the tests included in the standards. The manufacturer sends samples identified by the auditor to the laboratory.

TESTING

The laboratory performs the tests established by the standard and sends its report to AENOR.

GRANTING PROCEDURE

Using all the information on the activities performed, the Technical Certification Committee (independent body comprising all the interested parties: manufacturers, the Administration, users, monitoring entities and AENOR) will either propose to AENOR that the Mark be granted, or request that one of the activities be repeated due to non-compliance.

Once the Certificate has been granted, the process will continue as the monitoring activities required to keep it must be performed. Samples will be taken, and audits, inspections and tests will be performed on an annual basis. Results are assessed every year by the Technical Certification Committee, which will decide whether or not to maintain the Mark.

Once the certification process has been completed, organisations obtain: ​

• The AENOR product certificate
  
• A licence to use AENOR's Mark of certified products
