Scope
This standard specifies a general method for determining the combustion residue by weight method. This standard is applicable to the determination of the combustion residue of chemical reagents that can sublime or char and can completely remove the main body at 650℃±50℃. When determining the combustion residue with this standard, the residue mass obtained by calculating according to the sampling quantity and specification value shall not be less than 1 mg.
