This Section of BS 6043 describes an azeotropic distillation method for the determination of the water content of unbaked cold ramming pastes used in aluminium manufacture. The method is applicable to cold ramming pastes made with coal tar or bituminous binders, having water contents in the range 0.1 % to 2 % (m/m). The method is not applicable to cold ramming pastes made with resin-based binders, e.g. phenol-formaldehyde or foam types.
NOTE 1 Water contents in excess of 2 % (m/m) may be determined by using a larger receiver.
NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
