DANSK DS/EN 13137 PDF

This 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 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.
