The N Mark for structural concrete EHE-08 certifies the product's conformity with the regulatory requirements established in the Code on Structural Concrete, EHE-08, as well as with voluntary requirements included in the same Code, which imply a superior level of quality
The N Mark for structural concrete EHE-08 is an Officially Recognised Standard by the Ministry of Public Works, in accordance with the EHE-08.
This recognition facilitates the on-site reception of concrete with the AENOR Mark, which significantly reduces the number of required tests and applies more advantageous requirements, as well as simplifying the technical and documentation management of the project management. In terms of planning, structural savings are made by reducing the safety coefficient in calculations.
In addition, this certification scheme is accredited by the Spanish National Accreditation Body (ENAC) in accordance with UNE-EN-ISO/IEC 17065.
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.
Ready-mixed concrete used for residential properties with characteristic resistances between 20 and 100 N/mm2.
Certified concrete products must be included in the scope of application of the Structural Concrete Instruction EHE-08.
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 series of technical specifications that products and execution processes must meet. 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 application must include information about the company and the characteristics of the products for which certification is sought. In the case of concrete products, the certification is requested by “families” or groups of different designations of concrete with equivalent dosages.
Once the documentation has been analysed by AENOR technicians, the conformity assessment activities are commenced to verified that the products comply with current regulations:
A visit is made to the production centre to carry out the following procedures:
The test laboratory, accredited by ENAC, takes samples for consistency and compression resistance testing, 5 samples/month for 2 months before granting the Mark.
CONTINUOUS MONITORING OF THE PRODUCTION CONTROL
The manufacturer records the data obtained from all the production control tests in a software application authorised by AENOR. AENOR has continual access to this information of the manufacturer. It is extremely important that there is very little deviation in the production, which requires an exhaustive control of raw materials and all involved parameters.
The Technical Certification Committee (an independent body formed by all involved parties: manufacturers, management, users, testing agencies, and AENOR) analyses the reports of the activities carried out by the company (without knowing which company it is) and recommends AENOR either to grant the Mark or to request certain activities to be repeated by the company due to failing to meet the requirements.
The results are evaluated each year by the Technical Certification Committee which decides whether to maintain or remove the Mark.
Once an organisation passes the certification process, it obtains:
Environmental product declarations (EPD)
