ASTM D5029 – Standard Test Method for Water Solubles in Activated Carbon
Description:
Significance and Use
5.1 In certain applications, the ash, color, conductivity, or pH of the finished activated carbon product may be influenced by the quantity of water solubles it contains. This water solubles test provides a relative indication of the quantity of soluble materials that may be extracted from various activated carbons.
Scope
1.1 This test method covers the determination of the water-soluble content of (unused) granular and powdered activated carbons. Water solubles are materials that can be extracted by distilled water under reflux conditions and are expressed as a percentage of dry carbon weight.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
