测试步骤：
Test Procedure:
1.每一种类型的电池均应进行T1至T8 项试验。电池必须按顺序在相同的一组电池上进行试验T1至 T.5。试验T6和T8应使用未另外试验过的电池。试验T7可以使用先前在试验T1至T.5中使用过的未损 坏电池进行，以便测试进行在循环过的电池上。
Each battery type is subjected to tests T.1 to T.8. Tests T.1 to T.5 are conducted in sequence on the same battery. Tests 6 and 8 are conducted using not otherwise tested batteries. Test T.7 may be conducted using undamaged batteries previously used in Tests T.1 to T.5 for purposes of testing on cycled batteries.
2.为了量化质量损失，可用以下公式计算：质量损失 .(%)=(\mathsf{M}1-\mathsf{M}2)/\mathsf{M}1x100 In order to quantify the mass loss,thefollowing procedure is provided: Mass loss(%)=(M1-M2)/M1 x100
式中：M1是试验前的质量，M2是试验后的质量。如果质量损失不超过下表所列的数值，应视为"无质量损失”。
Where M1 is the mass before the test and M2 is the mass after the test.When mass loss does not exceed the values in Table below, it is considered as "no mass loss".
| 电芯或电池的质量 Mass M of cell or battery | 质量损失限值 Mass loss limit |
| M | 0.5% |
| 1g≤M≤75g | 0.2% |
| M>75g | 0.1% |
3.在测试T1至T4中，电池须满足无渗漏、无泄气、无解体、无破裂和无起火，并且每个试验电池在试验后的开路电压不小于其在进行这一试验前电压的 90% 。
In test T.1 to T.4, batteries meet this requirement if there is no leakage, no venting, no disassembly, no rupture and no fire and if the open circuit voltage of each test battery after testing is not less than 90% of its voltage immediately prior to this procedure.
