Moisture Content testing measures the moisture content of corrugated board.
The amount of moisture in the board has a significant effect in the material’s properties such as printability, shrinkage, dimensional stability, and physical strength.
In general, the less moisture there is residing in the board, the stronger the board will be and the longer it will hold its strength and shape.
Package testing and materials testing are important parts of the research and development process. Testing helps ensure that all corrugated board and new package designs are created specifically to handle real-world situations.
This specifies an oven-drying method for the determination of the moisture content of a lot of paper and board. The procedure describes how the test pieces are drawn from the lot. This is applicable to every type of lot of paper and board, including corrugated board and solid board, provided that the paper or board does not contain any substances, other than water, that are volatile at the temperature specified in this document.
Moisture applies to pulp, paper, paperboard, and paper products, except those containing significant quantities of materials other than water that are volatile. 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, determine the amount of moisture in shipping containers and calculate results of analysis of the moisture content on the original weight of the specimen.
