Cold atomic absorption spectrometry Mercury in moving and stationary batteries GB 8897. 2—2005
After removing the outer packaging of the battery, decompose it with nitric acid and hydrochloric acid and filter it. Part of the filtrate is taken out of the steam generator, and stannous fluoride is added to reduce the mercury ions to metal mercury. The mercury vapor is drawn into the absorption tube of the measuring instrument (or atomic spectrophotometer). Mercury atoms have characteristic absorption of the mercury resonance line with a wavelength of 253.7nm, and the absorbance is measured by this.

Technical differences
Added the requirements for the mercury content of batteries (mandatory clauses) and the requirements for the marking of mercury content in batteries.
Added the inspection methods, sampling and quality assurance, and inspection rules.
Proposed the minimum average discharge time (MAD) of some batteries (see Table F.2 for details).
Added the inspection method for the mercury content of batteries. Cause
According to the relevant regulations of my country on limiting the mercury content in batteries, the mandatory requirements for the mercury content in batteries and the requirements for their marking are added. The purpose is to list the corresponding test methods and sampling and quality assurance clause numbers specified in GB/T 8897.1, so that standard users can search accordingly.
IEC60086 does not specify specific inspection or acceptance rules. In order to suit my country's national conditions, ensure battery quality, and protect consumer interests, this part adds Appendix E Inspection Rules.
The actual discharge time of these batteries in my country is much higher than the IFC 60086-2 index.
Corresponding inspection methods are formulated in conjunction with the mandatory requirements for the mercury content of batteries.
