Название (англ.):
Liquid chlorine for industrial use; Determination of water content; Gravimetric method
Описание (англ.):
The method relates to the determination of the 'volatile water', that which volatilizes at the same time as the chlorine. It is applicable to productshaving a water content greater than 0,0005 % (m/m). It should not be applied to samples stored in bottles subject to corrosion.
