Standard Test Method for Trace Metal Content Analysis in Carbon Black

Importancia y uso:

5.1 This test covers the quantitation of trace metals in carbon black. The quantitation of heavy metals may help to estimate their contribution to a final finished article. Metal components may impact application properties of final products or may be a regulatory issue. It is the responsibility of the user of the material to consider the impact of the elements when designing a final product.

5.2 Elements which cannot be digested with nitric acid, such as silicon, cannot be quantified by this test method. This standard describes two digestion methods; microwave acid digestion and furnace ashing. The furnace ashing method may not be appropriate for certain more volatile elements which can be lost during incineration.
