N Mark for fixed vertical traffic signs

The N Mark certifies the quality of the fixed vertical signs used on motorways and urban roads

The objective of AENOR Certification for fixed vertical road signs is to ensure conformity with the requirements of each product. Among other things, this allows the manufacturer to demonstrate compliance with its customers' requirements, and, for products where this is relevant, compliance with regulations such as the General Technical Specifications Document for Roads and Bridges, PG-3

The N Mark covers the following products:

  • Retro-reflective directional signs and panels for traffic, made from a single sheet of galvanised steel UNE 135332:2013
  • Aluminium slats obtained by extrusion to create retro-reflective road signs UNE 135332:2013
  • Slats of galvanised steel sheets to create retro-reflective road signs UNE 135332:2013
  • Microprismatic retro-reflective sheets to be used in vertical traffic signs UNE 135340:2010, UNE 135340:2010/1M:2012
  • Retro-reflective sheets with glass beads to be used for vertical road signs UNE 135334:2011

As a compliance assessor, AENOR is a leading product certification entity. With over 100,000 certified references throughout more than 40 countries, the AENOR N Mark is among the top 5 product quality marks in the world. 

The AENOR N Mark is a voluntary marking that allows a company to demonstrate that its product complies with specific provisions compiled in a UNE, EN or ISO standard or in a technical specification. 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:


The manufacturer

  • Affords greater knowledge of the product via the exhaustive control set forth by the N​ Mark
  • Products that do not comply with relevant standards or regulations can be detected before they enter the market
  • Lowers the production costs since there is greater control during the manufacturing process.
  • There are commercial grounds to introduce the product into new markets and facilitate access to works

Business providers and monitoring agents

  • Guarantees that the product has undergone prior verification to determine its compliance with minimum requirements
  • Products with long-lasting confidence. Product assessments are ongoing, guaranteeing compliance with the initial certified provisions
​ ​

Public Administrations

​​​​​
  • ​​Guarantees that the prescribed product will comply with the applicable statutory requirements
  • Transparency of the AENOR certification process.
  • Strikes a balance among interested parties with regard to decisions on the certified products

The end user

​​​​​
  • Confidence from knowing that the product has undergone prior verification
  • Credibility; the product is assessed by a recognised certification entity

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, in which: ​

    • ​a) The quality management system is audited according to the requirements of UNE-EN ISO 9001 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 a laboratory which performs the tests included in the standards. The manufacturer sends samples identified by the auditor to the laboratory.

TESTING

The laboratory performs the tests established by the standard and sends its report to AENOR.

GRANTING

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 an organisation passes the certification process, it obtains: ​

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