| 1 | This standard describes the procedure for determination of solubility of pulp in one percent caustic soda solution. | |
| 2 | The determination of the solubility of pulp in caustic soda solution enables the assessment of degradation of pulps. Pulps which are relatively not unduly degraded during processing are relatively insoluble in dilute alkali solution. Degradation of cellulose is caused by drastic treatment during cooking or bleaching and results in loss of strength properties and opacity of the paper sheet made from the degraded pulp. | |
| 3 | In this revision, the standard has been updated to reflect the latest format and style of Indian Standards. | |
