IEC TS 62607-4-4:2016（E）是一项技术规范，为纳米储能装置的热失控质量水平测试提供了一种测量方法。该方法使用比较测量，使制造商能够根据试样的堆叠电极层数，确定储能装置中使用的纳米材料添加剂是否能够抵抗由两个或多个内部点之间的故障或意外低电阻连接引起的热失控。纳米材料添加剂可与正负电极、电解液、涂层电极或分离器等材料混合。 本文件包括术语定义、测试样本、穿刺针要求、测试程序、数据分析和结果解释方法以及案例研究。本文件不直接适用于储能装置产品的安全测试，因为这些产品中嵌入了复杂的安全设计方案。

IEC TS 62607-4-4:2016(E), which is a Technical Specification, provides a measurement method for thermal runaway quality level test for nano-enabled energy storage devices. This method uses comparative measurement to enable a manufacturer to decide whether or not the nanomaterial additives used in energy storage devices are resilient against the thermal runaway caused by a faulty or accidental low resistance connection between two or several internal points depending on the number of stacking electrode layers of the test sample. The nanomaterial additives may mix with the materials of positive and negative electrodes, electrolyte, coated on electrodes or separator. This document includes definitions of terminology, test sample, puncture nail requirements, test procedures, data analysis and methods of interpretation of results and a case study. This document does not apply directly to the safety testing for energy storage device products due to complex safety design schemes embedded in these products.
