The N Mark for solar thermal systems and collectors certifies the quality of these products
AENOR product certification is accredited by the ENAC and is recognised in the General Register of quality standards of the Technical Building Code (CTE), by the Directorate-General for Architecture and the Housing Policy of the Ministry of Public Works and Transport
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.
The products covered are liquid heating solar collectors, in accordance with the Standard
UNE-EN 12975-1, air heating solar collectors and thermal hybrid solar collectors (PVT), which falls under the scope of application of the Standard UNE-EN-ISO 9806, as well as solar thermal systems, in accordance with the Standard UNE-EN 12976-1.
As a compliance assessor, AENOR is a leading product certification entity. With over 100,000 certifications, the AENOR N Mark is present in over 40 countries and is in the top five most widely used product quality marks in the world.
The AENOR N Mark is a voluntary mark that allows the company to demonstrate that their product meets certain provisions established in a UNE, EN or ISO standard, or in a technical specification. This demonstration of compliance, based on a rigorous control performed by AENOR of the manufacturing processes and testing of end products will enable holders of the Mark to place high quality products on the market, which will help users to trust certified products.
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 CTE quality symbol. 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:
Business providers and monitoring agents
The end user
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.
Once AENOR technical staff have analysed the documents, compliance assessment activities will be performed in order to verify that the products comply with the applicable standards:
A visit is made to the production centre to carry out the following procedures:
The laboratory performs the tests established by the standard and sends its report to AENOR.
Using all the information on the activities performed, the Technical Certification Committee (independent body comprising all the interested parties: 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. Samples will be taken, and audits, inspections and tests will be performed on an annual basis. Results are assessed every year by the Technical Certification Committee, which will decide whether or not to maintain the Mark.
Once an organisation passes the certification process, it obtains:
Certified product sheet:Thermal insulation for construction
Virtual technical seminars:
AENOR certification for thermal insulators
The CE MARK is a passport for building products
The CE mark provides
access to the European Economic Area for construction products
Keymark European Mark
The voluntary CEN Mark to demonstrate compliance with European standards
Environmental product declarations (EPD)
AENOR manages the GlobalEPD Programme of verification, in accordance with Standards ISO 14025 and EN 15804
