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.
