Standard Test Method for Chromic Oxide in Ashed Wet Blue (Perchloric Acid Oxidation)
N D6714
Annotation
This test method covers the determination of chromic oxide in Wet Blue that has been partly or completely tanned with chromium compounds. In general the samples will contain chromium content between 1 and 5 %, calculated as chromic oxide expressed upon a dry basis otherwise referred to as moisture-free basis (mfb).
This test method is specific in that it applies to a sample or samples that are the resultant ash following the execution of Test Method D6716.
This test method does not apply to Wet White.
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. Specific hazards are given in Section 8.

Метод стандартной пробы для оксида хрома влажного синего цвета Ashed (окисление перхлорной кислоты)
Этот метод испытаний покрывает определение хромовой окиси Влажного Синего цвета, который частично или полностью загорелся с соединениями хрома. В целом образцы будут содержать содержание хрома между 1 и 5%, вычисленных как хромовая окись, выраженная на сухое основание, в других отношениях называемое основанием без влажности (mfb).
