As a compliance assessor, AENOR is a leading product certification entity. With more than 100,000 certified references, the AENOR N Mark, used in over 40 countries, is one of the 5 most widely-accepted quality marks in the world.

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 can provide the following advantages:

APPLICATION

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:

AUDIT/INSPECTION

A visit is made to the production centre to carry out the following procedures:

• a) the quality management system is audited in accordance with the UNE-EN ISO 9001 requirements that are directly related to the production process.
  
• b) The manufacturer's manufacturing process and production controls are inspected to ensure the product complies with the requirements of the standard.
  
• c) Samples are taken and sent to an accredited laboratory, which performs the tests included in the standards. The manufacturer sends samples identified by the auditor to the laboratory.
  

TESTING

The laboratory carries out the tests of the standard and send a report to AENOR.

GRANTING PROCEDURE

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 every year by the Plastics Certification Technical Committee, which decides whether or not to uphold the Mark

Once the organisation passes the certification process, it obtains: ​

• The AENOR product certificate
  
• A licence to use AENOR's Mark of certified products
