Abstract

This Uganda 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 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 volume from the thickness determinations. This standard is not applicable to corrugated fibreboard. In addition, the measurement of bulking thickness, method b) above, is not suitable for board. (This standard cancels and replaces US ISO 534:1995, Paper and board- Determination of thickness, density and specific volume, which has been technically revised). This standard was published on 2021-03-02.
