IEC 60317-68:2017+A1:2019规定了具有基于聚乙烯醇缩醛树脂的底涂层的120级漆包矩形铝绕组线的要求，如果其保留原始树脂的化学特性并满足所有规定的电线要求，则可以对其进行改性。本标准所涵盖的公称导体尺寸范围为 宽度:最小2.0 mm，最大16.0 mm 厚度:最小0.80 mm，最大5.60 mm 1级和2级导线包含在IEC 60317的这一部分中，适用于所有导体。宽度和厚度的指定组合以及特定的宽度/厚度比在IEC 60317-0-9:20 15中给出。该合并版本由第一版（2017年）及其修正案1（2019年）组成。因此，除本出版物外，无需下令修订。

IEC 60317-68:2017+A1:2019 specifies the requirements of enamelled rectangular aluminium winding wire of class 120 with a sole coating based on polyvinyl acetal resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The range of nominal conductor dimensions covered by this standard is
Width: minimum 2,0 mm and maximum 16,0 mm
Thickness: minimum 0,80 mm and maximum 5,60 mm
Wires of grade 1 and grade 2 are included in this part of IEC 60317 and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specific ratio width/thickness are given in IEC 60317-0-9:2015. This consolidated version consists of the first edition (2017) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
