Pulps. Preparation of laboratory sheets for the measurement of diffuse blue reflectance factor (ISO brightness)1 Scope This International Standard specifies two procedures for the preparation of laboratory sheets prior to measuring the diffuse blue reflectance factor (ISO brightness). One is the traditional procedure based on preparation of sheets in a Bchner funnel using a filter paper or a wire screen. In the other procedure, the sheets are prepared in a standard sheet former (conventional or Rapid Kthen). Details of the subsequent measurement procedure are
