Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 20155-2006 "Determination of mercury, cadmium and lead in batteries".
Compared with GB/T 20155-2006, the main technical changes of this standard are as follows.
--- Revised the scope of application of the standard (see Chapter 1);
--- Increased handling of battery pack samples (see 6.2);
--- Revised "Ammonia content determination cold atomic absorption spectrometry AAS" (see Chapter 7,.2006 edition 2.1);
--- Added "Measurement of cadmium and lead content by flame atomic absorption spectrometry FAAS" (see Chapter 9,.2006 and 2.2 and 2.3).
This standard was proposed by the China Light Industry Association.
This standard is under the jurisdiction of the National Primary Battery Standardization Technical Committee (SAC/TC176).

Rinse immediately with plenty of water and seek medical attention if it is severe.
1 Scope
This standard specifies the detection method for mercury, cadmium and lead in batteries.
This standard is applicable to mercury, cadmium and lead in small sealed primary batteries complying with GB/T 8897.2 and the mass of single cells is not more than.200g.
Determination of the content.
Measurement range. mercury content 0.05μg/g~100mg/g; cadmium content 1.0μg/g~100mg/g; lead content 5.0μg/g~100mg/g.
Note. The lower limit of the measurement range of each element varies with the precision performance of the instrument and the dilution factor at the time of preparation of the sample solution. Reduce the total volume of the sample solution or
Increasing the sample weight can reduce the lower limit of the measurement range of mercury, cadmium and lead. For example, when the accuracy of the instrument meets the requirements of this standard, when the sample is
When the total volume of the solution is half of the "Table 1 battery mass range, model example and reagent amount added", the lower limit of the measurement range is. mercury 0.025 μg/g,
Cadmium 0.5μg/g, lead 2.5μg/g; when the sample solution is prepared with a dilution factor of 5 (battery sample mass 20g sample solution total volume 100mL), measured
The lower limit of the range is. mercury 0.01 μg/g, cadmium 0.2 μg/g, lead 1.0 μg/g.
