Paper and board. Determination of thickness, density and specific volume Ingestion-build-73935 This British Standard specifies requirements1 Scope 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. 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
