The N Mark for corrugated sheets of fibre cement allows the manufacturer to demonstrate compliance with requirements established in the Technical Building Code (CTE)

The N Mark for corrugated sheets of fibre cement include requirements of European and national standards for different kinds of sheets, and allows the manufacturer to demonstrate compliance with regulatory requirements in force in Spain, such as the Technical Building Code (CTE).

AENOR product certification for corrugated sheets of fibre cement 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 corrugated sheets of fibre cement covers the products included in the following standards:

  • UNE-EN 494 Placas onduladas de fibrocemento. Requirements, compliance assessment, classification and designation
  • ​UNE 88113 Placas onduladas o nervadas de cemento reforzado con fibras con PUR incorporado y revestimiento inferior de poliéster, y sus piezas complementarias de cubierta. Requirements and testing methods

AENOR, and as a conformity assessment entity, is a leader in product certification. With over 100,000 certified references throughout more than 40 countries, the AENOR N Mark is among the top 5 product quality marks in the world. 

The AENOR N Mark is a voluntary marking that allows a company to demonstrate that its product complies with specific provisions compiled in a UNE, EN or ISO standard or in a technical specification. This demonstration of compliance during the manufacturing and testing of the final products, based on a rigorous control performed by AENOR, will allow licensees of the Mark to put their products on the market with a high standard of quality, instilling confidence in the users of these certified products.

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


The manufacturer

  • Affords greater knowledge of the product via the exhaustive control set forth by the N​ Mark
  • Products that do not comply with relevant standards or regulations can be detected before they enter the market
  • Lowers the production costs since there is 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

  • Guarantees that the product has undergone prior verification to determine its compliance with minimum requirements
  • Products with long-lasting confidence. Product assessments are ongoing, guaranteeing compliance with the initial certified provisions
​ ​

Public Administrations

​​​​​
  • ​​Guarantees that the prescribed product will comply with the applicable statutory requirements
  • Transparency of the AENOR certification process.
  • Balance of partes stakeholders in the decisions on certified products

The end user

​​​​​
  • Confidence from knowing that the product has undergone prior verification
  • Credibility; the product is assessed by a recognised certification entity

The certification for corrugated fibre cement plates consists of two clearly distinct phases. In the first phase, certification applicants must implement a documentation system based on ISO 9001. At the same time, the product and measuring equipment must be monitored as set out in the certification regulations.​

Subsequently, AENOR's Technical Services visit the production facility in order to verify compliance with the requirements of the certification document. Samples of the models are taken and sent to one of the laboratories accredited by ENAC for certification. These laboratories collaborate with AENOR in the certification process.​

After receiving test results, AENOR, acting as the Office of the Technical Certification Committee, presents a confidential report of all activities which is evaluated by the Committee.​

If the decision is affirmative, AENOR will be asked to grant certification; if negative, the petitioner will be informed of the causes of the refusal and any additional activities that must be done.​

After issuance of the certificate, the company progresses to 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. In this visit, samples of the certified models are taken on a rotational basis for testing in the certified 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 activities are required.

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

  • AENOR product certificate
  • A licence to use AENOR's Mark of a certified product, in accordance with the provisions of AENOR regulations
