ISO standard: Determining moisture content of paper and board
In the paper and board trade, the moisture content is important since it influences converting processes, such as printing and copying. The moisture content also has an influence on curl and dimensional stability.
In January NEN-EN-ISO 287:2018 was published. This standard specifies an oven-drying method for the determination of the moisture content of a lot of paper and board. It 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 (World Packaging Standardisation Newsletter, January 2018).
