| 1 | This standard describes the procedure for determination of copper number of bleached and purified pulps. | |
| 2 | Copper number may be regarded as the index of the reducing groups of cellulose, sugars and impurities possessing reducing properties present in the pulp. As the hydrolyzed or oxidized cellulose is capable of reducing certain metallic ions like copper to lower valence states, the reaction of this type has served to detect damage to cellulose and to estimate the quantity of reducing groups. | |
| 3 | In this revision, the standard has been updated to reflect the latest format and style of Indian Standards. | |
