Wood-plastics composites (WPC) - Part 1: Test methods for characterisation of WPC materials and products
This Technical specification specifies test methods and their relevant parameters and test conditions to be used in determining selected properties of wood-plastics composites, usually called WPC, materials and products. It is applicable to cellular or non-cellular WPC materials processed through plastics processing techniques, as defined in Clause 3.
The properties have been selected from the test methods usually used in the plastics and wood fields.
These test methods are primarily intended to be used for the characterisation of WPC materials (see CEN/TS 15534-2 [1]) and WPC products (see CEN/TS 15534-3 [2]).
NOTE This document may be revised when other parts of CEN/TS 15534 are being amended or added.
The purpose of this document is to provide test methods to assess a wide range of performance characteristics for WPC materials and products. But, all the characteristics listed in this part of CEN/TS 15534 are not necessarily to be assessed for a given application.
This Technical Specification takes into account the current state of the art and is intended to be used by WPC material suppliers and converters. No limitation has been introduced for the content of cellulosic materials.
Holz-Polymer-Werkstoffe (WPC) - Teil 1: Prüfverfahren für die Beschreibung von WPC-Werkstoffen und -Erzeugnissen
Diese Technische Spezifikation legt Prüfverfahren und die jeweiligen Parameter sowie die Prüfbedingungen fest, die zur Bestimmung der Eigenschaften von Werkstoffen und Erzeugnissen aus Holz-Kunststoff-Verbund¬stoffen, üblicherweise WPC genannt, angewendet werden. Sie gilt für verschäumte oder nicht ver¬schäumte Holz-Kunststoff-Verbundstoffe, die durch Verarbeitungsverfahren für Kunststoffe nach Abschnitt 3 hergestellt werden.
Die Eigenschaften wurden anhand der Prüfverfahren gewählt, die üblicherweise im Kunststoff- und Holzbereich angewendet werden.
Diese Prüfverfahren sind in erster Linie für die Beschreibung von WPC-Werkstoffen (siehe prEN/TC 15534-2) und WPC-Erzeugnissen (siehe prEN/TS 15534-3) vorgesehen.
ANMERKUNG Dieses Dokument kann überarbeitet werden, wenn andere Teile von prEN/TS 15534 geändert oder hinzugefügt werden.
Zweck dieses Dokumentes ist die Festlegung von Prüfverfahren zur Bewertung einer Vielzahl von Leistungs¬merkmalen für Werkstoffe und Erzeugnisse aus WPC. Jedoch müssen für einen gegebenen Anwendungsfall nicht notwendigerweise alle in diesem Teil von prCEN/TS 15534 aufgeführten Eigenschaften bewertet werden.
Diese Technische Spezifikation trägt dem aktuellen Stand der Technik Rechnung und sie ist für die Anwendung durch Lieferer und Verarbeiter von WPC-Werkstoffen vorgesehen. Es wird keine Beschränkung für den Zellstoffgehalt angegeben.

(voir prCEN/TS 15534-2) et des produits en WPC (voir prCEN/TS 15534-3).
NOTE Le présent document est susceptible de révision après amendement ou adjonction d'autres parties de
la prCEN/TS 15534.
L'objectif de ce document consiste à fournir des méthodes d'essai permettant d'évaluer un large éventail de
caractéristiques de performance des matériaux WPC et produits en WPC. Il n'est cependant pas
nécessairement requis pour une application donnée d'évaluer toutes les caractéristiques listées dans la

CEN/TS 15534 consists of the following parts, under the general title Wood-plastics composites (WPC):
Part 1: Test methods for characterisation of WPC materials and products
Part 2: Characterisation of WPC materials
Part 3: Characterisation of WPC products.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
The denomination “wood-plastics composites”, WPC, is usually used to designate materials or products made
of one or more natural fibres or flours and a polymer or a mixture of polymers. Natural fibres and flours come
from different vegetable sources (e.g. wood, hemp, sisal, jute, kenaf, rice) and all kind of polymers (virgin or
recycled) can be used but currently the most common ones are poly(vinyl chloride) PVC, polypropylene (PP)
and polyethylene (PE).
WPC materials can be considered neither as filled plastics nor as a special kind of wood. They should be
considered as a different material having their own characteristics.
The main applications of WPC products are at present decking, siding, cladding, panelling and fencing
furniture. WPC materials can be processed by different techniques, as extruding for profiles and pipes,
calendering for films and sheets or injection moulding. The contents of natural fibres and polymers depend on
the application and the processing techniques.
As the market of WPC materials and products is currently growing in Europe, there is a lack of harmonisation
for the test methods needed to characterise WPC materials and products and for the specifications they
should comply with. Up to now, each branch of industry has its own practice and used its own test methods. In
this context, a European Technical Specification seemed to be the best choice to increase the experience and
knowledge in order to guarantee that quality products in this new market. The status of Technical Specification
has also been chosen because the WPC materials and products and their characteristics are not sufficiently
known for the time being.
It consists of the following parts:
Part 1: to identify the test methods and their relevant parameters and test conditions to be used for the
determination of the characteristics of WPC materials and products;
Part 2
