1.1 These test methods cover four ashing methods for cellulose. These are intended for use on unbleached and bleached cellulose in sheeted or bulk fiber form. Each one of the test methods has advantages, so that preference applications exist for all four.
1.2 The test methods appear as follows:
|
| Sections |
| Test Method A—Ash in Cellulose at 575°C | 6 to 11 |
| Test Method B—Sulfated Ash in Cellulose at 575°C | 12 to 17 |
| Test Method C—Ashing Cellulose by Schoniger Oxidation | 18 to 22 |
| Test Method D—Wet Ashing of Cellulose for Inorganics | 23 to 29 |
