IEC 61340-4-8:20 14提供了一种测试方法，用于评估根据IEC 61340-5-3的要求测试的静电屏蔽袋的性能。测试设备的设计电压为1 000 V直流。本标准中提出的试验方法也可应用于屏蔽袋以外的包装。本标准的目的是确保使用本试验方法评价给定包装材料的试验实验室将获得相似的结果。本标准不涉及电磁干扰（EMI）、射频干扰（RFI）、电磁脉冲（EMP）的防护，也不涉及挥发性物质的防护。与上一版相比，此版本包括以下重大技术变更: a)修改标题，在“放电屏蔽”之前加入“静电”一词；b)删除标准参考ANSI/ESD STM5.1和ASTM D-257-78，并由标准参考IEC 61340-3-1和IEC 60093代替； c)增加了对IEC 61340-5-3的新规范性引用，因为屏蔽袋的要求已包含在本标准中； d)英制单位已被删除。

IEC 61340-4-8:2014 provides a test method for evaluating the performance of electrostatic discharge shielding bags tested according to the requirements of IEC 61340-5-3. The design voltage for the test apparatus is 1 000 V d.c. The test method presented in this standard can also be applied to packaging other than shielding bags. The purpose of this standard is to ensure that testing laboratories who use this test method to evaluate a given packaging material will obtain similar results. This standard does not address protection from electromagnetic interference (EMI), radio frequency interference (RFI), electromagnetic pulsing (EMP) nor protection against volatile materials. This edition includes the following significant technical changes with respect to the previous edition:
a) modification to the title to include the word "Electrostatic" before discharge shielding";
b) removal of normative references ANSI/ESD STM5.1 and ASTM D-257-78 and replaced by normative references IEC 61340-3-1 and IEC 60093;
c) new normative reference to IEC 61340-5-3 added, because the requirement for shielding bags have been included in this standard;
d) imperial units have been removed.
