Specifies a method to determine the "Kjeldahl Nitrogen" in sludge and sludge products. Digestion is catalysed by copper or selenium, the temperature being raised by a high concentration of sodium sulphate. Although wet samples are usually taken for analysis, it is recognized practice to report results on a dry mass basis (g/kg).
