N Mark for fire hydrants

N Mark for fire hydrants

This certification helps manufacturers to demonstrate compliance with the statutory requirements established in the regulations for fire protection systems (RIPCI)

The N Mark for pillar fire hydrants and underground fire hydrants certifies conformity with applicable requirements and allows the manufacturer to demonstrate compliance with the regulatory requirements established in the fire protection facilities regulation (RIPCI). The AENOR Mark is also recognised by the Ministry of Transport and Public Works as a symbol of CTE quality

AENOR product certification enables fire hydrants to be received on-site, thus reducing the tests and checks required and helping site management to manage technical matters and documents.

The N Mark for fire hydrants is accredited by the National Accreditation Entity (ENAC).

The N Mark for fire hydrant outlets covers the following products:

  • Pillar fire hydrants UNE-EN 14384
  • Underground fire hydrants UNE-EN 14339

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 logo that enables a company to demonstrate that their product complies with the specific provision of a UNE, EN or ISO standard, or a technical specification. This display of conformity is based on rigorous monitoring of manufacturing processes and testing of end products carried out by AENOR, and enables holders of the N Mark to place their high-quality certified products on the market and to instil confidence in customers.

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:

The manufacturer

  • Better understanding of a product due to the exhaustive control the AENOR Mark establishes with respect to the same
  • Products that do not comply with relevant standards or regulations can be detected before they enter the market
  • Decreases production costs as a result of 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

  • Ensures that products used in works comply with applicable regulatory requirements
  • Guarantee that the product has previously been verified in order to determine compliance with the minimum requirements of basic CTE documents

The end user

  • Properties are built using materials of proven quality
  • Product certified by a renowned entity and global leader in certifying building products

Royal Decree 513/2017, which approves the Regulation on Fire Protection Facilities, establishes that compliance with the requirements laid out therein for devices, equipment, systems or their components, must be proved, when determined, which is the case with fire hydrants, through third-party certification that allows for the use of the corresponding mark, such as the AENOR Mark.

The certificate of conformity with standards established by the AENOR Mark for fire hydrants helps to prove compliance with the requirements of the RIPCI.


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 technicians have analysed the relevant documents, compliance activities will commence to verify that products comply with applicable regulations:


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.


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 successfully completed, the organisation obtains: ​ ​

  • The AENOR product certificate
  • User licence for the AEN​​OR ​Mark of certified products
