The N Mark for bituminous waterproofing membranes certifies the quality of bituminous sheets with reinforcement for waterproofing coatings, modified bitumen sheets and bituminous plaques with reinforcement
The N Mark for bituminous waterproofing membranes certifies the requirements of the following products, based on European and national standards:
The AENOR certification demonstrates that manufacturers or installers comply with customer requirements.
AENOR product certification is accredited by the National Accreditation Entity (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.
As a compliance assessor, AENOR is a leading product certification entity. The AENOR N Mark now features on more than 100,000 certified products in more than 40 countries and is one of the world's five most popular quality marks.
The AENOR N Mark is a voluntary mark that enables companies to demonstrate that their products comply with certain requirements set forth in a UNE, EN, ISO standard or technical specification. This proof of compliance, based on AENOR's rigorous monitoring of manufacturing processes and final product tests, will enable holders of the Mark to place products of a high quality and standard on the market, which will instil confidence in the users of 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 standard of quality of the CTE. 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 certification process consists of the following phases:
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 quality management system is audited every two years according to requirements of UNE-EN ISO 9001 directly related to the production process.
There is a twice-yearly inspection of the manufacturing process and production controls carried out by the manufacturer to ensure product compliance with the requirements of the standard.
Samples are taken twice a year and sent to a certified laboratory to perform the tests established in standards. The manufacturer sends samples identified by the auditor to the laboratory.
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. The results are assessed every year by the Technical Certification Committee which decides whether to maintain or remove the Mark.
Once the certification process has been completed, organisations obtain:
The CE MARK is a passport for building products
The CE mark provides
access to the European Economic Area for construction products
Environmental product declarations (EPD)
AENOR manages the GlobalEPD Programme of verification, in accordance with Standards ISO 14025 and EN 15804
