Continuous quality control

Nueva Terrain has two laboratories in its facilities where all of the tests, controls and verifications required in order to assure the quality of the end product and offer reliable and durable systems to the market are carried out.

The implemented quality system controls the process from the reception of the raw material to the delivery of the end product to the client, thus ensuring that all of the phases of the different intermediary processes are carried out correctly in order to obtain a top-quality product.

The laboratories are equipped with the necessary instrumentation to carry out all of the tests required by the product’s standards. Plastometers, furnaces, Vicat devices, dichloromethane baths, traction machines, pressure stations, are a few of the pieces of equipment available.

As well as the technical means, we have a human team with vast product experience and knowledge, which is fundamental when detecting possible deviations or suggesting improvements in design and performance.


The first thing to take into account when any product is manufactured is to ensure that the dimensions obtained match the design requirements and comply with the product's regulations. This is fundamental to ensure compatibility and offer a system wich is coherent, mechanically speaking.

There is three-dimensional coordinate measurement machinery to evaluate the finished product in a reliable manner wich measures both the fitting and the piping in otder to give the go-ahead to the production batches.

Ensayo ciclo térmico

El laboratorio central de Nueva Terrain está equipado para realizar el ensayo de ciclo térmico, posiblemente el más exigente en cuanto a sistema de unión. Se trata de un ensayo dinámico en el que se cambian constantemente las condiciones de presión y temperatura, buscando poner las uniones al límite y así asegurar su correctos funcionamiento en condiciones de uso.

Es el ensayo que más esfuerzo requiere para su realización, implica tener funcionando un sistema complejo de bombas, electroválvulas, enfriadoras, etc, durante varios meses, llevando un control diario de los parámetros de presión y temperatura.

Ensayos de presión interna

Los ensayos más habituales para comprobar la resistencia de las tuberías y accesorios fabricados son los ensayos de presión interna. Éstos permiten comprobar que se cumplen las exigencias solicitadas por las normas de producto y validar la producción.

Se realizan con agua fría a 20ºC y con agua caliente a 95ºC, utilizando las presiones y tiempos determinados por las normas.

El laboratorio central de Nueva Terrain dispone de varios baños con control de temperatura y presión que nos permiten realizar este tipo de ensayo diariamente.


El laboratorio central cuenta con estufas para ensayar la estabilidad térmica, máquina de tracción para ensayar comportamientos mecánicos, máquina para conocer el grado Vicat de la gama de PVC, útiles para realizar ensayos de Pull-out a toda la gama, puestos de ensayo a presión interna tanto a 20ºC como a 95ºC, plastómetro, balanza de precisión, etc...

Además también se cuenta con los aparatos necesarios para realizar las calibraciones de los instrumentos de presión, temperatura y masa, y así poder asegurar una consistencia en las medidas tal como se exige en el sistema de calidad certificado.


In accordance with the European Commission's overall sustainability objectives, specifically for the piping sector, a series of ambitious agreements have been established with the aim of improving the sustainability of our processes, qualities and solutions, as well as reducing energy consumption during manufacturing.

We can therefore say that the plastic piping manufacturing industry is leading the way in terms of the European objectives for the protection of the environment.

Nueva Terrain

The key points of our zero aggression towards the environment objective, in general terms, are:

  • PB is the optimum material in application for DHW: it is less thick and therefore its ecological footprint is smaller.
  • Own manufacturing: therefore the control and management is completely internal. The fact that we focus on national or European providers allows us to have a direct relationship with the process.
  • Ambitious objectives for the reduction of energy and water consumption and recycled use for products of lower demand.
  • Waste management: reduction, assessment and management of hazardous waste by authorised agent.
  • Manufacturing plants and commercial offices in strategic locations, as well as shared transport policies.

Environmental Product Declarations (EPD)

Nueva Terrain has the Environmental Product Declarations (EPD) for its PVC drainage systems (in compliance with the UNE EN 1329 regulation) and supply of cold and hot water in PB (in compliance with the UNE EN 15876 regulation).

The reports (VITO Institute) include the following files:

  • Product Environmental Statement, with the results obtained.
  • Life Cycle Assessment of the product, where the methodology followed is explained.
  • Certification of the autonomy and reliability of the study by a third party.


There is currently no European common requirement, but the Dutch legislation is believed to be the most rigorous in terms of compliance regarding products that come into contact with drinking water.

Nueva Terrain has chosen this legislation to certify the potability of its water supply system in construction.

Polybutylene (PB) is a material with excellent organoleptic qualities, highlighting that no additive is added during its transformation.
