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.Papers with a thickness less than 100 µm are measured as a pack of sheets.This International Standard 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 volumefrom the thickness determinations.This International Standard is not applicable to corrugated fibreboard. In addition, the me
