N Mark for water supply valves

The N Mark is the symbol of product quality and safety and is backed by an independent third-party entity. The AENOR N Mark logo is recognised by public and private customers, facilitating the sale of thousands of certified products around the world.

The N certification is not mandatory; the manufacturer subjects itself voluntarily to a complete examination of its product by independent entities and specialists, with the goal of objectively determining that the product meets the established quality and safety requirements.

The AENOR certification is the benchmark in Spain for water supply valves and is recognised by the companies comprising the water services industry in Spain.

Products that receive this mark undergo different assessments and controls to ensure their compliance with corresponding standards and with the specific certification system developed by AENOR for each product.

AENOR certification for these types of products covers the following equipment and fittings:

• Shut-off valves (e.g. gate, butterfly), in accordance with standard UNE-EN 1074-1 and UNE-EN 1074-2.
• Toggle and relief valves, in accordance with standard UNE-EN 1074-1 and UNE-EN 1074-4.

Everything is easier with the AENOR certification:

• A leading quality mark that gives assurance to customers.
• AENOR certification enables these products to be sold and installed in water supply networks, as it is recognised on the market (suppliers, installers, product distributors, etc.).

Guarantees compliance with public and private requirements

AENOR certification for water supply valves enables manufacturers to demonstrate compliance with the requirements of the standards water suppliers must comply with.

The following activities are performed in order to grant the N Mark for gas facility equipment and fittings:

• Initial tests performed in the AENOR laboratory on equipment/fittings samples selected from manufacturing centres.

• The product is inspected and the quality assurance system used to manufacture the products is audited in order to check that the particular requirements put in place in order to manufacture the product have been complied with.

• Facilities are monitored on a regular basis in order to check that the original approval conditions of the quality assurance system have been maintained. Product samples are also taken from manufacturing centres in order to undergo partial testing at the AENOR laboratory.

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

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