Determination of total organic carbon in limestone

Le présent document spécifie les méthodes de détermination de la teneur en carbone organique total (COT) du calcaire. Il décrit la méthode de référence et les variantes qui peuvent être considérées comme équivalentes. En cas de litige, seule la méthode de référence est utilisée. Toute autre méthode peut être utilisée, à condition qu'elle soit étalonnée soit sur la méthode de référence, soit sur des matériaux de référence acceptés internationalement, afin de démontrer son équivalence.
