IEC 62899-202-4:20 21（E）定义了用于通过印刷形成可拉伸导体的可拉伸印刷层（例如导电油墨）、从导电油墨获得的可拉伸导电膜以及由具有绝缘体的导电油墨组成的可拉伸印刷布线的特性的术语和测量方法。 由本文件处理的可拉伸印刷层(导电和绝缘)适用于印刷在可拉伸基底上的可拉伸电线，例如织物集成的可穿戴设备、皮肤可贴片设备等。

IEC 62899-202-4:2021(E) defines the terminology and measurement methods for the properties of stretchable printed layers, such as conductive ink, for forming stretchable conductors by printing, stretchable conductive films obtained from conductive ink, and stretchable printed wiring consisted by conductive ink with insulator.
Stretchable printed layers (conductive and insulating) handled by this document apply to the stretchable electric wiring printed on stretchable substrates, for example fabric integrated wearable devices, skin patchable devices, and so on.
