Carbon materials - Determination of Porosity
1 Scope
This standard specifies the principles for determination of apparent porosity carbon materials, equipment, samples, test procedures, test results.
This standard applies to carbon materials for determination of apparent porosity. Determination of apparent porosity, there are two, namely vacuum method and the boiling method. In secondary
When cutting analysis, using vacuum method.
