N Mark for baked clay paving stones

The N Marker baked clay paving stones 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 baked clay paving stones 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 baked clay paving stones 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.

The N Mark for baked clay paving stones covers products included in Standard UNE-EN 1344 Baked clay paving stones

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 display of conformity is based on rigorous monitoring of manufacturing processes and testing of end products carried out by AENOR, and enables holders of the N Mark to place their high-quality certified products on the market and to instil confidence in customers.

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 paving stones comprises two clearly differentiated stages. 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 of the models to be certified are taken and sent to one of the laboratories, accredited by ENAC, that collaborate with AENOR in the certification process.

Once the test results have been received, AENOR, which acts as Secretary to the Technical Certification Committee, will issue a confidential report on all activities, which will be assessed by the Committee.

If the application is successful, AENOR will be asked to grant the certificate. If not, the applicant will be notified of the reasons why its application was rejected and told what additional measures to take.

​​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, the Secretariat prepares a report on all activities developed, which is presented to the Committee. When seeing the results obtained, the Committee decides whether the certificate is upheld or whether extraordinary actions are required.

Once the certification process has been successfully completed, the organisation obtains: ​ ​

  • AENOR product certificate and its technical annex
  • Licence to use the AEN​OR Mark ​for a certified product, in accordance with AENOR's regulations
