ASTM D4933
Full Name
ASTM D4933 – Standard Guide for Moisture Conditioning of Wood and Wood-Based Materials
Scope
ASTM D4933 provides standard procedures for conditioning and equilibrating wood and wood-based materials to a constant moisture content. The scope of the standard includes:
- Materials: it applies to solid wood, wood-based fiber and particle materials and panels, and wood products containing adhesives.
- Procedures: the guide outlines procedures for conditioning wood and wood-based materials to a desired moisture content, including both accelerated and non-accelerated methods. It also provides guidance on selecting the appropriate conditioning time and method based on the intended use of the material.
- Applications: the standard is intended for use in research and development activities, testing laboratories, quality control, and by producers and users of wood and wood-based materials.
- Background Information: the guide provides background information on the importance of moisture content control, definitions of key terms, technical data on the relationship between moisture content and relative humidity, and descriptions of various types of conditioning apparatus.
Overall, ASTM D4933 is a valuable resource for anyone working with wood and wood-based materials. It provides standardized procedures for moisture conditioning, ensuring consistent and reliable results in testing and research.
