This Part of BS 4651 describes a gravimetric method for the determination of the residue after heating at 850 °C of ammonia solution for industrial use.
The method is applicable to solutions containing 25.0 % to 35.0 % (m/m) ammonia and with a residue after heating at 850 °C of not lower than 3 mg/kg.
NOTE The publications referred to in this standard are listed on the inside back cover.
Applicable to ammonia solutions of concentrations within the range 25% to 35%, by mass, and with a residue after heating of not less than 3 mg/kg.
