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 575oC | 6 to 11 |
| Test Method B-Sulfated Ash in Cellulose at 575oC | 12 to17 |
| Test Method C-Ashing Cellulose by Schoniger Oxidation | 18 to 22 |
| Test Method D-Wet Ashing of Cellulose for Inorganics | 23 to 29 |
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
