Standard Test Method for Stability of Cellulose Fibers in Alkaline Environments
N D6942
Annotation
This test method describes a procedure for determining the effect of exposure to alkaline environments on the strength of cellulose fibers. An alkaline environment is defined to be any matrix in which the pH is greater than 8 for a period of 2 or more hours.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
Автоматический перевод:
Метод стандартной пробы для стабильности целлюлозных волокон в щелочной окружающей среде
Этот метод тестирования описывает процедуру для определения эффекта воздействия щелочных сред на основании волокон целлюлозы. Щелочная среда определяется, чтобы быть любой матрицей, в которой pH больше, чем 8 сроком на 2 или больше часа.
Значения, утвержденные в единицах СИ, должны рассматриваться как стандарт. Никакие другие единицы измерения не включены в этот стандарт.
