Methylene chloride for industrial use — List of methods of test

Specifies the sampling, the determination of residue on evaporation, the determination of distillation characteristics, the determination of density at 20 °C, the determination of acidity, the determination of water and the measurement of colour. The determination of distillation characteristics indicates either the temperatures corresponding to the collection of each of two volumes of distillate, V0 and V1, or the difference between these two volumes. These two volumes will be indicated in the specification for dichloromethan agreed between the interested parties. Replaces ISO Recommendation R 1869-1970.
