DIN 19539:2016-12

This standard specifies a method for the differentiated determination of the content of organic carbon (TOC₄₀₀) released up to 400 °C, residual oxidizable carbon (ROC) (including lignite, hard coal, charcoal, diesel soot) and inorganic carbon (TIC₉₀₀) released up to 900 °C. The method is based on dry combustion in the oxygen stream to carbon dioxide by means of temperature gradients from 150 °C to 900 °C in dry solid samples of soil with technogenic admixtures as well as solid waste with contents of carbon dioxide. The basis is the dry combustion in the oxygen stream to carbon dioxide by means of temperature gradients from 150 °C to 900 °C in dry solid samples of soil, soil with technogenic admixtures as well as solid waste with contents of more than 1 g carbon per kg (0,1 % C) (per carbon species in the measurement sample).
