B. What constitutes a design change requiring renewed design type testing?
B--在IATA DGR 规定中，什么样的设计变化需要进行重新型号测试？
The following provisions are taken from the 5th revised edition of the UN Manual of Tests and Criteria.
以下条款由第５次更新的联合国测试手册中提出
A cell or battery that differs from a tested design by:
电池芯或者电池与测试设计时的不同的判断基于：
(a) For primary cells and batteries, a change of more than 0.1 g or 20% by mass, whichever is greater, to the cathode, to the anode, or to the electrolyte;
电池阳极、阴极或电解液的质量有大于20%或大于0.1g 的改变
(b) For rechargeable cells and batteries, a change in Watt-hours of more than 20% or an increase in voltage of more than 20%; or
对于可以重复充电的电池芯和电池，额定能量变化大于20%或者电压升高超过20%的；
(c) A change that would materially affect the test results
产品的变动将显著的改变试验结果的
Shall be considered a new type and shall be subjected to the required tests.
这几点都应被看作是新的型号，需要接受新的测试
In the event that a cell or battery type does not meet one or more of the test requirements, steps shall be taken to correct the deficiency or deficiencies that caused the failure before such a cell or battery type is
retested.
若电池和电池芯不满足测试要求的，在重新测试之前，需要修正其导致失败的缺陷再进行测试。
