IEC 62899-402-2:20 20(E)描述了印刷电子产品中印刷图案边缘波纹度的测量方法。 该文件包括测量程序，以及边缘波纹度的定义和相关属性，如边缘波纹度的平均边缘、触摸边缘和分布边缘，这些属性与图形艺术印刷或蚀刻工艺中出现的边缘波纹度有很大不同。

IEC 62899-402-2:2020(E) describes the measurement methods of the edge waviness of printed patterns in printed electronics.
This document includes the measurement procedure, as well as the definition of edge waviness and related attributes such as average edge, touch edge and distribution edge of edge waviness, which are quite different from those that appear in the printing of graphic arts or from etching processes.
