1.1 本指南涵盖了适用于评估木塑复合材料（WPC）产品广泛性能的测试方法。它是根据实验产品和当前制造的产品的评估开发的，并不是为了表明列出的所有测试对于WPC的每个应用都是必要的或合适的。用户必须确定哪些测试方法适用于正在评估的特定应用（请参阅 附录X1 ). 1.2 制造过程的细节可能是专有的，不在本指南的范围内。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 WPC适用于结构和非结构应用。本文中所述的测试方法旨在解决由原始或回收木材和热塑性材料制成的产品。这些方法为评估对WPC的结构和非结构用途重要的几种机械和物理性能提供了参考。

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 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.
