Ash Content Apparatus

Ash Content Apparatus

An Ash test involves taking a known amount of sample, placing the weighed sample into a dried / pre-weighed porcelain crucible, burning away the polymer in an air atmosphere at temperatures above 500°C, and weighing the crucible after it is has been cooled to room temperature in a desiccator.
Ash residue remaining in the crucible is considered filler unless the residue is less than 1%.
Residues of less than 1% are typically the result of additives that did not burn off.

Data:
The Ash test result is expressed as % ash.
A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both.
The total ash content equals the weight of the ash divided by the weight of the original sample multiplied by 100%.
