The N Mark for plastic piping systems for hot, cold and central heating water (PEX, PP, RP, PERT, CPVC, Multi-layer) certifies that these products comply with national and European standards
AENOR product certification is an essential tool for increasing product quality. It provides the consumer with greater confidence in the product, improves sales and facilitates insertion into new markets
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 in 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.
The AENOR certified product N Mark is 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 N Mark covers the following products:
As a compliance assessor, AENOR is a leading product certification entity. AENOR's N Mark is one of the world's top five product quality marks. In total, more than products have been certified with an N Mark in more than 40 countries.
AENOR's N Mark is voluntary and enables companies to demonstrate that their products comply with the service provision requirements of UNE, EN and ISO standards or technical specifications. This demonstration of compliance during the manufacturing and testing of the final products, based on a rigorous control performed by AENOR, will allow licensees of the Mark to put their products on the market with a high standard of quality, instilling confidence in the users of these certified products.
This way, the AENOR N Mark provides 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 the documentation is analysed by AENOR technicians, the conformity assessment is initiated 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 Plastics Certification Technical Committee (an independent body established by 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 result is assessed on a yearly basis by the Certification Committee Technical for Plastics, who decides whether the Mark is retained
Once the organisation passes the certification process, it obtains:
CTC Committee 001 for Certified Plastic
Environmental product declarations (EPD)
AENOR manages the GlobalEPD Programme of verification, in accordance with Standards ISO 14025 and EN 15804
