The N Mark certifies compliance with the requirements applying to steel products for concrete under the Instruction on Structural Concrete EHE-08
The N Mark for steel products for concrete certifies conformity with the requirements of the Code on Structural Concrete EHE-08, which assures the manufacturer that their customers can benefit from the advantages that the EHE-08 reserves for officially recognised standards. For those not regulated by the Instruction, the objective is to provide demonstration of compliance with the national UNE or European EN standards and with other requirements demanded by customers.
The N Mark for steel products for concrete is accredited by the National Accreditation Entity (ENAC) and is an Officially Recognised Standard, in accordance with the Code on Structural Concrete (EHE-08).
Certification is the action carried out by an independent body, which manifests that an organisation, product, process or service meets the requirements defined in certain standards or technical specifications. AENOR marks prove this certification and constitute a distinguishing factor on the market, improving the image of products and services and building trust among customers and consumers:
The AENOR N certified product mark demonstrates compliance with certain standards. It is a symbol of product quality and safety, and is backed by an independent third party, AENOR, a leader in certification. The AENOR N Mark logo is recognised by public and private users, facilitating the sales of thousands of certified products around the world.
AENOR's N certified product marks are not mandatory; manufacturers can voluntarily submit their products to be fully assessed by independent agencies and specialists in order to objectively ensure that they comply with the quality and safety requirements set forth in the corresponding regulations. The AENOR N mark therefore supplements the CE mark for products covered by harmonised directives and regulations. AENOR N marks are of particular value to customers when the product at issue is not covered by a CE mark.
AENOR performs its own certification system in order to certify each product, which uses applicable standards, technical specifications, certification procedures and features.
AENOR, a conformity assessment company, is a leader in product certification. With more than 100,000 certified references, the AENOR N Mark is present in over 40 countries and is among the top 5 product quality markings 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. AENOR's robust inspection of the manufacturing processes and testing of end products allows licensees of the Mark to put products on the market with a high standard of quality, creating trust between the manufactures and the users of their certified products.
The Code on Structural Concrete EHE-08, approved by Royal Decree 1247/2008, of 18 July, establishes a set of technical specifications that must be met by the products and execution processes included in this field. While voluntary, these certified products can boast quality markings that guarantee their compliance with standards, regulatory provisions or individual regulations from issuing agencies.
The AENOR N Mark bears the recognition of the Ministry of Public Works as an officially recognised logo under the EHE-08. Any product with the officially recognised logo is one with a level of guarantee higher than the minimum level required under EHE-08. The logo implies having undergone a rigorous product control during its manufacture; external verification with testing performed in independent laboratories accredited by ENAC, in accordance with the standard EN ISO 17025; audits and inspections of its facilities, raw materials and quality system. The companies that issue these certificates are accredited by ENAC in accordance with the standard EN ISO 17065 and are guaranteed by the Public Administration that handles official recognition (Royal Decree 1247/2008 approving the EHE-08).
This way, the AENOR N Mark provides the following benefits:
Planners and builders
Technical management and ownership
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 request includes both company information and product characteristics for those who request the certification.
Once the documentation is analysed by AENOR technicians to verify that the products comply with implementation standards, the conformity assessment activities begin:
AENOR conducts a visit to the production centre, where:
The laboratory performs the tests established by the standard and sends its report to AENOR.
GRANTING OF CERTIFICATION
Using all the information from the aforementioned activities, the Technical Certification Committee (an independent body formed by all stakeholders): 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. Conducts the auditing activities, inspection, sample taking and testing on a semi-annual or annual basis. The result is evaluated by the Technical Certification Committee who decides whether the AENOR certification is retained.
Once an organisation passes the certification process, it obtains:
Environmental product declarations (EPD)
EPD for construction steel in accordance with Standard EN 15804
The CE MARK is a passport for building products
The CE mark provides
access to the European Economic Area for construction products
