Full Description ADOPTED_FROM:EN 15169:2007 This European Standard specifies a method for the determination of the loss on ignition. This procedure is applicable to all kinds of waste, sludge and sediments. The loss on ignition is often used as an estimate for the content of non-volatile organic matter in waste, sludge and sediments. It should be noted that any content of elementary carbon and volatilisation of organic materials or chemical reactions by inorganic compounds, is included in the loss on ignition.
