给出了适用于负载印刷线路板涂层（保形涂层）的电绝缘材料的性能要求。 符合本规范的材料符合既定的性能水平。然而，用户为特定应用选择材料时，应基于该应用中充分性能所需的实际要求，而不是仅基于本规范。 本版本与前一版本相比包括以下重大技术变更: a） 增加了清洁要求； b） 增加了基于IEC 61086-2修改的新特性； c） 其中包括用于航空航天应用的3级材料。

Gives the property requirements for electrical insulating materials suitable for application as coatings for loaded printed wire boards (conformal coatings). Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. This edition includes the following significant technical changes from the previous edition: a) requirements for cleaning have been added; b) new properties based on modifications to IEC 61086-2 have been added; c) a Class 3 material for aerospace applications has been included.
