IEC 62742:2021规定了非金属船体船舶电气和电子设备电磁兼容性(EMC)的发射、抗扰度和性能标准的最低要求。 注:IEC 60533给出了金属船体的要求。本文件作为IEC 60533的扩展，以满足非金属船体的EMC影响。 该文件进一步给出了如何在船体(表面)由非金属材料制成的船舶上实现电磁兼容性(EMC)的指导，并且也可用于船体由金属船体组成但具有非金属上层建筑或部件的船舶。 本文件有助于满足IMO第A.813(19)号决议的要求。 它没有规定设备的电击防护和介电测试等基本安全要求。电磁对人类的影响不是本文件的主题。

IEC 62742:2021 specifies minimum requirements for emission, immunity and performance criteria regarding electromagnetic compatibility (EMC) of electrical and electronic equipment for ships with non-metallic hull.
NOTE Requirements for metallic hull are given by IEC 60533. This documents acts an extension of IEC 60533 to cater for EMC effects on non-metallic hull.
This document further gives guidance on how to achieve electromagnetic compatibility (EMC) on ships whose hull (surface) is made from non-metallic material and can also be useful for ships with hull comprising of a metallic hull, but with non-metallic superstructure or components.
This document assists in meeting the requirements of IMO resolution A.813(19).
It does not specify basic safety requirements such as protection against electric shock and dielectric tests for equipment. Electromagnetic effects on human beings are not the subject of this document.
