Specifies the sampling, the determination of distillation characteristics, the determination of density at 20 °C, the determination of crystallizing point and the determination of o- and p-chlorotoluene content. The determination of distillation characteristics indicates the difference between the temperatures corresponding to the collection of two volumes of distillate, V0 and V1. These two volumes will be indicated in the specification of product agreed between the interested parties. For the determination of o-chlorotoluene, reading, from the crystallizing point diagram or from a table, of the o-chlorotoluene content corresponding to the crystallizing point of the sample. Replaces ISO Recommendation R 1696-1970.
