Specifies two methods of measuring the thickness of paper and board and of calculating the apparent sheet density from the thickness determinations. This Standard is based on ISO 534:1988 and incorporates amendments which provide that the ISO preferred pressure between the faces be mandatory and allow the Standard to be applied to corrugated fibreboard.

This International Standard specifies two methods of measuring the thickness of paper and board and of calculating the apparent bulk density or the apparent sheet density from the thickness determinations. The methods area) measurement of single sheets of paper or board (single sheet thickness);b) measurement of a pack of sheets of paper of grammage up to 224 g/m2(bulking thickness).Method b) is applicable to corrugated fibreboard. Neither method is applicable to certain soft papers such as tissues which are creped and/or embossed due to the slow or excessive compression which takes place when measurements are made on such materials.
