IEC 61249-8-7标准规定了非导电膜和涂层的标记传说油墨的要求。这些油墨用于在电子设备和电气设备中标记电路板、元器件和其他部件。标记传说油墨必须符合以下要求：

1. 耐热性能：标记传说油墨必须能够在高温下保持稳定，不褪色、不变形或不剥落。

2. 耐化学性能：标记传说油墨必须能够抵抗化学物质的侵蚀，如酸、碱、溶剂等。

3. 耐磨性能：标记传说油墨必须能够抵抗磨损和刮擦，不易剥落或褪色。

4. 色彩稳定性：标记传说油墨的颜色必须稳定，不受光照、氧化或其他因素的影响而改变。

5. 粘附性能：标记传说油墨必须能够牢固地附着在材料表面上，不易剥离或脱落。

6. 可印性能：标记传说油墨必须能够在印刷过程中均匀地涂布在材料表面上，不产生滴落、流淌或其他不良现象。

IEC 61249-8-7标准还规定了标记传说油墨的颜色、粘度、干燥时间、密度、PH值等物理和化学性质的要求。此外，标记传说油墨还必须符合环保要求，不得含有有害物质。

IEC 61249-8-7标准的实施可以保证非导电膜和涂层的标记传说油墨的质量和性能符合国际标准，从而提高电子设备和电气设备的可靠性和安全性。
