ISO 534:2005 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 the following calculation methods, from the thickness determinations:calculation methods for the apparent sheet density and for the apparent bulk density; calculation methods for the apparent specific sheet volume and for the apparent specific bulk volume.It is not applicable to corrugated fibreboard, and method a) is not applicable to materials with a grammage higher than 225 g/m2.
