ASTM D1105 is the standard test method for preparation of extractive-free wood, providing a consistent approach for removing extractives before further evaluation. This matters because extractives can influence analytical results, comparison of wood samples, and downstream testing reliability. By using ASTM D1105, laboratories and quality teams can prepare wood specimens in a controlled way that supports more dependable measurements and better repeatability when working with wood materials.

What is ASTM D1105?

ASTM D1105, Standard Test Method for Preparation of Extractive-Free Wood, describes a laboratory procedure for conditioning wood so that extractives are removed before additional testing or analysis. The standard is used as a technical reference when the presence of naturally occurring soluble substances could affect results. In practice, it helps establish a more uniform test material, supporting consistent sample preparation and improving comparability across wood testing workflows and related quality control activities.

Where is ASTM D1105 used?

This standard is commonly used in wood testing laboratories and research settings where extracted or chemically prepared wood samples are needed for further evaluation. It is relevant to workflows that involve wood specimen preparation before analytical testing, comparative studies, or product characterization. ASTM D1105 may also be used by manufacturers, material evaluators, and quality control teams that need a repeatable method for preparing wood samples in a controlled and documented manner.

Why is ASTM D1105 important?

ASTM D1105 helps reduce variability caused by extractives, which can otherwise interfere with test results or obscure true material behavior. Using a recognized ASTM standard supports consistency in sample preparation, strengthens quality control, and improves confidence in product evaluation and research findings. For organizations that rely on wood testing, it can also aid procurement decisions, internal specifications, and compliance-oriented documentation by providing a clear, repeatable preparation method.
