Measurement of hygroexpansivity of paper and board - Method for measurement of hygroexpansivity up to a maximum relative humidity of 86% Ingestion-build-73073 protective systems and components atWhat is BS 6712 2 Hygroexpansivity measurement of paper and board about? The measurement of dimensional changes in paper and board with changes in the ambient humidity is necessary for accurate control of printing and similar processes. The change in length, or hygroexpansivity, is due to stress relaxation of the paper fibres and swelling or contraction of the fibres by absorption or desorption of water. The proportion of the two mechanisms effective
