Standard Test Method for Carbon Black—Non-Dispersible Matter by Mechanical Flushing (NDM)
N D7724
Annotation
This test method covers the determination of nondispersible matter after mechanical water flushing of regular untreated carbon blacks. It may not be applicable to oil-treated carbon blacks because the oil would prevent proper wetting of the black by water.
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:
Стандартный метод испытаний для сажи — недисперсный вопрос механическим устройством, сбрасывающим (NDM)
Этот метод тестирования покрывает определение недисперсного вопроса после механического водного сбрасывания обычных необработанных углеродных черных цветов оттенков. Это не может быть применимо к рассматриваемым с нефтью углеродным черным цветам, потому что нефть предотвратила бы надлежащее смачивание черного цвета водным путем.
