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:
SectionsTest Method A-Ash in Cellulose at 575oC6 to 11Test Method B-Sulfated Ash in Cellulose at 575oC12 to17Test Method C-Ashing Cellulose by Schoniger Oxidation18 to 22Test Method D-Wet Ashing of Cellulose for Inorganics23 to 291.3 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.
