ASTM D1109 is the ASTM standard for the 1% sodium hydroxide solubility of wood, providing a defined test method for evaluating how wood responds to this chemical solution. It is commonly used as a technical reference when comparing wood materials, supporting consistent testing and interpretation across labs or procurement workflows. By focusing on a specific solubility measurement, ASTM D1109 helps users apply a repeatable method for quality control, material assessment, and standards-based documentation.

What is ASTM D1109?

ASTM D1109, Standard Test Method for 1% Sodium Hydroxide Solubility of Wood, establishes a recognized procedure for measuring the solubility behavior of wood in a dilute sodium hydroxide solution. The standard is primarily a test method, so its value lies in creating a common basis for obtaining comparable results. In practical terms, it supports technical evaluation of wood by giving laboratories and buyers a consistent way to assess this specific property under controlled conditions.

Where is ASTM D1109 used?

This standard is typically used in wood testing environments where laboratory personnel need a repeatable method for evaluating a sample’s response to 1% sodium hydroxide. It may be applied in material qualification, incoming inspection, comparative testing, or research settings involving wood products. ASTM D1109 is also relevant for organizations that document product characteristics, verify consistency between batches, or align internal testing practices with a published ASTM standard.

Why is ASTM D1109 important?

ASTM D1109 matters because it helps reduce ambiguity in wood testing and supports more reliable comparisons between results from different users or facilities. A defined standard test method can improve consistency in quality control, procurement decisions, and product evaluation. For organizations that rely on technical documentation, using ASTM D1109 may also support compliance-focused workflows and lower the risk of misinterpreting test outcomes tied to wood solubility behavior.
