EVS-EN ISO 534:2005

This International Standard specifies two methods for measuring the thickness of paper and board: a) the measurement of a single sheet of paper or board as a single sheet thickness; b) the measurement of a pack of sheets of paper as a bulking thickness. It also specifies calculation methods - for the apparent sheet density and for the apparent bulk density, and - for the apparent specific sheet volume and for the apparent specific bulk volume from the thickness determinations.
