Characterization of waste - Determination of total organic carbon (TOC) in waste, sludges and sediments

Scope

This European Standard specifies two methods for the determination of total organic carbon (TOC) in undried waste samples containing more than 1 g carbon per kg of dry matter (0,1 %).
This standard can be applied as well to sludges, sediments and comparable materials.
When present, elemental carbon, carbides, cyanides, cyanates, isocyanates, isothiocyanates and thiocyanates are determined as organic carbon using the methods described in this standard. An interpretation of the measured value may therefore be problematical in cases where the waste contains relevant levels of the above mentioned components. If needed, these components shall be determined separately by means of a suitable validated procedure and be recorded in the test report.
NOTE At the time of publication of this European Standard a standardized procedure for determination of elemental carbon in waste is not available.
