TAPPI T 412 – Moisture in Pulp, Paper and Paperboard

TAPPI T 412 om-16 applies to pulp, paper, paperboard, and paper products, except those containing significant quantities of materials other than water that are volatile at lower than 107C (224.6 F)or degrade above 103C (217.4F). 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.
