1 Scope

This Technical Specification identifies the required and optional properties of wood-plastics composite (WPC)products. It is intended to be used as a basis for the specifications of WPC products. This part is applicable to WPC products intended to be used as decking and siding.NOTE Other applications may be covered when this document will be revised.
