    ASTM D7031

    Significance and Use

    WPCs are intended for use in both structural and non-structural applications. The test methods described within are intended to address products that are manufactured from virgin or recycled wood and thermoplastic sources. These methods provide a reference for the evaluation of several mechanical and physical properties important for structural and non-structural uses of WPCs.

    1. Scope

    1.1 This guide covers test methods appropriate for evaluating a wide range of performance properties for wood-plastic composite (WPC) products. It was developed from evaluations of both experimental and currently manufactured products, and is not intended to suggest that all the tests listed are necessary or appropriate for each application of a WPC. The user must determine which test methods apply to the particular application being evaluated (see Appendix X1).

    1.2 Details of manufacturing processes may be proprietary and are beyond the scope of this guide.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
