Overview

CEN/TS 15534-2:2007 defines the framework for characterisation of wood-plastic composites (WPC) used as the basis for material specifications. The Technical Specification identifies which properties are required and which are optional, and indicates the relevant test methods (specified in CEN/TS 15534-1). Suppliers are expected to provide a technical data sheet with declared tolerances and any purchaser-required information on constituents and legal use.

Key Topics

• Required vs Optional Characteristics: The document divides material characteristics into required (R) and optional (O) lists for external and internal use, enabling consistent specification and communication between suppliers and purchasers.
• Core material properties: Examples of characterised properties include density, moisture content, heat deflection temperature (HDT), flexural properties, tensile properties, creep behaviour, swelling and water absorption, and linear thermal expansion.
• Durability and biological resistance: The specification references test methods for resistance to termites, basidiomycetes, soft rotting micro-fungi, and discolouring micro‑organisms and algae where relevant to application.
• Test method linkage: Characterisation shall be assessed using test methods given in CEN/TS 15534-1, with numerous normative references to established EN and ISO standards (for example EN ISO 1183 for density, EN ISO 75 for HDT, EN ISO 178 for flexural properties, EN 317 for swelling).
• Technical data templates: Annex A provides example templates for required and optional characteristics for both external and internal use, assisting suppliers to prepare standardized data sheets.

Applications

CEN/TS 15534-2:2007 is practical for:

• Material specification and procurement: Define the minimum and optional properties required for purchase contracts and tender documents.
• Quality control and acceptance testing: Use the listed characteristics and referenced methods to assess incoming materials and ensure conformity with declared values and tolerances.
• Product development and formulation: Guide R&D teams on which material attributes to target for specific performance (e.g., decking vs internal components).
• Regulatory and compliance documentation: Support documentation for legal use of constituents and disclosure required by purchasers.

Related Standards

Relevant documents and parts referenced in the Technical Specification include:

• CEN/TS 15534-1 - Test methods for characterisation of WPC materials and products
• CEN/TS 15534-3 - Characterisation of WPC products (companion part)
• Selected EN/ISO standards cited for specific tests (e.g., EN ISO 1183, EN ISO 75, EN ISO 178, EN 317, EN 1534, EN 117 and ISO 16979).

By aligning material specifications with CEN/TS 15534-2:2007, manufacturers, specifiers and purchasers can achieve clearer communication, reproducible testing and consistent quality across WPC supply chains.

This Technical Specification (CEN/TS) was approved by CEN on 29 December 2006 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
