1.3 Definitions定义
For the purpose of this International Standard, the following definitions apply.
1.3.1 Sealed nickel-metal hydride cell密封镍金属氢化物电池
Cell which remains closed and does not release either gas or liquid when operated within the
limits of charge and temperature specified by the manufacture. The cell may be equipped with a safety device to prevent dangerously high internal pressure. The cell does not require addition to the electrolyte and is designed to operate during its life in its original sealed state.
Note: The nickel-metal hydride cell, however, may release gas towards the end of its life due to the accumulation of hydrogen in the cell.
1.3.2 Small prismatic cell小型方形电池
Cell in the form of a rectangular parallelepiped whose width and thickness dimensions are not more than 25 mm.
1.3.3 Nominal voltage of a sealed nickel-metal hydride rechargeable cell标称电压
The nominal voltage is 1.2V. 标称电压为1.2V
1.3.4 Rated capacity额定容量
Quantity of electricity C5Ah (ampere-hours) declared by the manufacturer which a single cell can deliver when discharged at the reference test current of 0.2 It A to a final voltage of 1.0V at +20 after charging, storing and discharging under the specified conditions(see clause 4).
制造商标称的以A.H安培小时为单位的电量C5 即单体电池在第4章规定的条件下经充电搁置和放电之后在20℃条件下以5h 率放电至电压为1.0V时多能提供的电量

1.4 Parameter measurement tolerances测量参数公差
The overall controlled or measured values, relative to the specified or actual values, shall be within these tolerances:
a) 1% for voltage1%电压
b) 1% for current1%电流
c) 1% for capacity1%流量
d) 2 for temperature2温度
e) 0.1% for time0.1%时间
These tolerances comprise the comprise the combined of the measuring instruments, the measurement techniques used, and all other sources of error in the test procedure.
For assistance in selecting instrumentation, see IEC 60051 for analogue instruments and IEC 60485 for digital instruments. The details of the instrumentation used shall be provided in any report results.
