Scope

Applies to the chemical determination of free or total carbon content in parts in which carbon is uniformly distributed and present in the forms shown in table 1. Combined carbon is determined as the difference between total and free carbon. The presence of carbonaceous materials in the pores or on the surface interferes with the determination of carbon, see table 2.
