This standard specifies two empirical methods for the quantitative determination of the loss of
mass from a plastic material under defined conditions of time and temperature, in the presence of activated carbon.
These methods are used, in particular, for the quantitative determination of the loss on heating of plasticizers from plasticized plastic materials, in which case it is generally assumed that no significant amounts of other volatile materials are present.
These are empirical test methods, suitable only for a rather rapid comparison of the losses of plasticizers or, in general, of volatile compounds, from different plastics.
