ASTM D7031
Full Name
ASTM D7031 – Standard Guide for Evaluating Mechanical and Physical Properties of Wood-Plastic Composite Products
Scope
ASTM D7031 provides a comprehensive guide for evaluating the mechanical and physical properties of wood-plastic composite (WPC) products. It encompasses a wide range of test methods suitable for assessing the performance of these materials in various applications.
The scope of ASTM D7031 includes:
- Mechanical properties:
- Flexural properties (strength and modulus)
- Tensile properties (strength and modulus)
- Compressive properties (strength and modulus)
- Shear properties
- Impact resistance
- Creep and creep rupture
- Fatigue properties
- Fastener performance
- Physical properties:
- Density and specific gravity
- Water absorption and thickness swelling
- Linear thermal expansion
- Color stability
- Weathering resistance
- Durability and service life prediction
- Applications:
- The guide is applicable to a variety of WPC products, including decking, railing, fencing, siding, and other outdoor building materials.
- It assists manufacturers, specifiers, and consumers in selecting appropriate test methods and evaluating the performance of WPC products for specific applications.
- Limitations:
- The guide does not prescribe specific test methods for each application, but rather provides a framework for selecting the most relevant tests based on the intended use of the product.
- It does not cover all possible properties of WPC products, but focuses on the most critical mechanical and physical properties relevant to their performance and durability.
By offering a standardized approach for evaluating WPC products, ASTM D7031 helps ensure the quality, consistency, and reliability of these materials in various applications, contributing to their wider acceptance and adoption in the construction and building industry.
