Moisture in pulp, paper and paperboard, Test Method TAPPI/ANSI T 412 om-16
The following procedure applies to pulp, paper, paperboard, and paper products, except those containing significant quantities of materials other than water that are volatile at lower than 107°C (224.6°F) or degrade above 103°C (217.4°F). Moisture is significant for economic reasons and for its effect on such properties as printability, shrinkage, dimensional stability, physical strength, and paper runnability.
This method should be followed to:
Determine the amount of moisture in a lot of pulp, paper or paperboard as an “as received” moisture.
Determine the amount of moisture in shipping containers.
Calculate results of analysis of the moisture content on the original weight of the specimen.
