The N Mark certifies conformity with the requirements applicable to cement, demonstrating conformity with the Code on Receiving Cements (RC-16) and the applicable articles of the Code on Structural Concrete (EHE-08)
The N Mark for cement certifies conformity with the applicable provisions and requirements, beyond standardised measures, whilst also guaranteeing compliance with both national and European regulatory requirements, including the Code on Receiving Cements (RC-16) and the part of the Code on Structural Concrete (EHE-08) that applies to cement. Furthermore, and in accordance with Presidential Order PRE/1954/2004, which implements Directive 2003/53/EC, the N Mark complies with the requirement of water-soluble chromium content (VI) in cement.
The cement N Mark is accredited by the Spanish National Accreditation Entity (ENAC), is an Officially Recognised Symbol in accordance with the Cement Reception Instruction (RC-16) of the Ministry of Public Works and Transport and is declared by the Ministry of Industry as an alternative to regulatory approval in accordance with Royal Decree 1313/1988, which stipulates that all cement used to manufacture concrete and mortar for all types of prefabricated works and products must be approved.
AENOR is accredited by ENAC to certify compliance with the regulatory requirements on cement not subject to the CE mark (white cement and SRC sulphate and seawater resistant cement) and to authorise distribution centres for all types of cement, in accordance with Royal Decree 605/2006, which approves the procedures for the application of Standard UNE-EN 197-2:2000 with regard to cement not subject to the CE mark and distribution centres for all types of cement.
AENOR certification enables manufacturers to place cement on the market and reassures users as it reduces the risk undertaken by consumers to a minimum level. It therefore facilitates on-site reception, reducing mandatory controls and thus facilitating the technical and documentary management on site. This cuts costs for all parties.
A very notable feature of AENOR certification is the monitoring of certified cement on the market, thus not only guaranteeing that the product complies with the established provisions, but also that it maintains the characteristics and properties from the time of its manufacture.
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.
1. Cement in accordance with Standard UNE-EN 197-1
Some of the above cement products may also contain the following properties:
2. Cement resistant to sulphates, according to Standard UNE 80303-1 (not included in Standard UNE-EN 197-1)

4. Cement with low hydration heat, according to Standard UNE-EN 14216
5. Cement for masonry, according to Standard-EN 413-1
6. White cements according to Standard UNE 80305, i.e. cements that, as well as meeting any of the Standards UNE-EN 197-1, UNE-EN 14216 or UNE EN 413-1, also meet the whiteness requirement
7. Calcium aluminate cement, according to Standard UNE-EN 14647

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 mark that enables companies to demonstrate that their products comply with certain features of a UNE, EN or ISO standard or 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 Cement Reception Instruction (RC-16) approved by Royal Decree 256/2016 establishes a set of technical specifications that cement must comply with until it is delivered. 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 is recognised by the Ministry of Public Works and Transport as the officially recognised symbol (DOR) of the RC-16. Products featuring an officially recognised quality assurance symbol have a greater level of guarantee than the minimum required by the RC-16, as they are subject to rigorous product controls during the manufacturing process, external verification via testing at ENAC accredited laboratories in accordance with EN ISO 17025 and audits and inspections of facilities, raw materials and quality control system. Certified cement is also monitored in the market. The entities that issue these certificates are accredited by ENAC in accordance with StandardEN ISO 17065 and guaranteed by the Public Administration responsible for official recognition.
This way, the AENOR N Mark provides the following advantages:
Planners and builders
Technical management and ownership
By continually assessing cement on a monthly, quarterly and half-yearly basis, it is possible to pre-empt any incidents that may arise in connection with meeting compliance criteria.
Through the contrasting tools used by AENOR, mantiene the manufacturer's laboratory used for self-monitoring is maintained supervised, so that the relevant corrections are made and issues are avoided. Checks are also performed to verify that manufacturers' laboratories comply with the assurance requirements of laboratories that are verified via five annual inter-laboratory programmes and with the participation of a long list of both national and international laboratories (accredited, official, manufacturers, monitoring).
AENOR subjects cutting devices to monitoring programmes in order to ensure that the reference equipment AENOR uses serves as an assurance standard for the manufacturer and as a monitoring standard for the verifying laboratory.
The measuring equipment AENOR uses in its factory inspections features the calibrations used by ENAC accredited laboratories in order to ensure metrological traceability.
AENOR certifies cement by means of the following activities:
The process ensures that the quality assurance system model used to manufacture and dispatch cement is based on ISO 9001 within the factory, at all distribution points and as regards monitoring transportation.
The process employed to monitor cement is exhaustive and monitors both the compliance of raw materials and the origin of the same.
For those cases where additional specifications must be checked using standardised methods in accordance with the relevant regulations due to the market's, the users' or the manufacturer's own requirements.
Once the certification process has been completed, the organisation will obtain:
Environmental product declarations (EPD)
EDP for cements 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
