Ceramic tiles N mark

The N Mark for ceramic tiles certifies conformity with applicable requirements and allows the manufacturer to demonstrate compliance with regulatory requirements in force in Spain, such as the Technical Building Code

AENOR product certification for ceramic tiles facilitates on-site reception, which allows for reduced testing and verifications and thus facilitating the technical and documentary management on site.

The N Mark for ceramic tiles is accredited by the National Accreditation Entity (ENAC) and their products are registered in the register of the Technical Building Code (CTE) as officially recognised quality standards, by the Ministry of Public Works and Transport.

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 product complies with certain features stipulated by a UNE, EN or 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 manufacturer

  • Better understanding of a product due to the exhaustive control the AENOR Mark establishes with respect to the same
  • Products that do not comply with relevant standards or regulations can be detected before they enter the market
  • Decreases production costs as a result of greater control during the manufacturing process
  • There are commercial grounds to introduce the product into new markets and facilitate access to works

Business providers and monitoring agents

  • Fewer or no checks upon delivery are required for goods provided for by the CTE
  • Decreases the time it takes to perform the work
  • Ensures that products used in works comply with applicable regulatory requirements
  • Guarantee that the product has previously been verified in order to determine compliance with the minimum requirements of basic CTE documents

The end user

  • Properties are built using materials of proven quality
  • Product certified by a renowned entity and global leader in certifying building products

​​Certification of ceramic tiles comprises two clearly differentiated phases. In the first phase, certification applicants must implement a documentation system based on ISO 9001. At the same time, they must control the products and measurement equipment as set out in the certification regulations.

Subsequently, AENOR's technical services visit the production facility to verify compliance with the certification document requirements. Samples are taken from the models that are to be certified and then sent to one of the laboratories accredited by the Spanish National Accreditation Body (ENAC), which collaborates with AENOR in the certification process.

​​Once the results of the tests have been received, AENOR evaluates the activities and issues an opinion on them.
If the decision is satisfactory, AENOR will be recommended to grant the certificate. Alternatively, the applicant will be informed of the reasons for refusal and specific complementary activities that need to be carried out.

​​Once the certificate has been issued, the company enters the certification monitoring phase. During this phase, AENOR's services make annual visits to the production facilities to confirm that the criteria and requirements established in the certification regulations are being applied and maintained. During the visit, samples of the certified models are taken on a rotational basis for testing in an accredited laboratory.

Each year, AENOR reviews all activities developed. When seeing the results obtained, it decides whether the certificate is upheld or whether extraordinary actions are required.

After completing the certification process, the organisation obtains:

  • AENOR product certificate and its technical annex
  • Licence to use the AENOR Mark of a certified product, in accordance with the provisions of AENOR regulations
