ASTM D1110-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Test Methods for
1,2
Water Solubility of Wood
This standard is issued under the fixed designation D1110; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 These test methods cover the determination of the water solubility of wood. Two methods are given, as follows:
1.1.1 Method A—Cold-Water Solubility—This method provides a measure of the tannins, gums, sugars, and coloring matter in the
wood.
1.1.2 Method B—Hot-Water Solubility—This method provides a measure of the tannins, gums, sugars, coloring matter, and
starches in the wood.
1.2 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.3 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.
2. Significance and Use
2.1 Cold water removes a part of such extraneous materials as tannins, gums, sugars, and coloring matters. Hot water removes
these plus the starches.
METHOD A—COLD-WATER SOLUBILITY
3. Apparatus
3.1 Filtering Crucibles—Alundum or fritted-glass crucibles of coarse porosity will be required.
3.2 Filtering Flask—A suction filtering flask, equipped with a rubber flange for the crucible and funnel, shall be provided.
These test methods are under the jurisdiction of ASTM Committee D07 on Wood and are the direct responsibility of D07.01 on Fundamental Test Methods and Properties.

4. Test Specimen
4.1 The test specimen shall consist of 2 g of air-dried sawdust or milled wood that has been ground to pass through a 425-μm
(approx. 40 mesh) sieve and be retained on a 250-μm (approx. 60 mesh) sieve.
5. Procedure
5.1 Place a 2-g test specimen, the moisture content of which has been previously determined, in a 400-mL beaker, and cover with
300 mL of distilled water. Let this mixture digestsolvate at a temperature of 23 6 2°C, 2 °C, with frequent stirring, for 48 h.
5.2 Filter the material on an Alundum or fritted-glass
