2.4 Cell Drawing
See Appendix
2.5 Appearance
The cell shall not have any defects that may affect their commercial values,including obvious
scratches,cracks,rust stains,discoloration,or electrolyte leakage.
3 Test Conditions and Methods
3.1 Environmental Conditions
Unless otherwise specified,the test should be carried out in an environmental temperature of
25°C±2°C,relative humidity of 10%～90%,and atmospheric pressure of 86 kPa to 106 kPa.The room
temperature mentioned in this
specification refers to 25C±2℃.
3.2 Measuring Instruments
The accuracy of measuring device should meet the following requirements:
A.Voltage measuring device ：±0.05 % FS;
B.Current measuring device ：±0.05 % FS;
C.Temperature measuring device
：
±1℃;
D.Dimension measuring device ：±0.01 mm;
E.Weight measuring device
：
±0.1 g
。
Note:During the testing process,voltage,current,ambient temperature,and cell temperature must be
recorded.It is recommended to collect the cell temperature at the terminal and the center of large
surface (or side).
3.3 Test Clamp Preparation and Installation
3.3.1 Ordinary Steel Clamp
The single cell shall be clamped with steel splints(thickness:10 mm).The splints need to cover the
large surfaces of the cell and be fixed with 6 M8 bolts.All sides of the splints need to be covered
with insulating film Clamp as shown below:
