EN/IEC 60945 EMC (Electromagnetic Compatibility) requirement also addresses the standard for the anti-interference of the radio frequency between the nearby electronic devices. However, to ensure the devices can operate as required in the presence of electrical and electromagnetic interference and other electrical threats. A marine device or part should also be capable and not cause a short circuit when operating under the wide temperature from -15°C up to 55°C and a wide range of humidity from 5％～95％. Considering the environment is necessary to meet at least IP65 for water and dust protection. Det Norske Veritas standard for certification No 2.4 (DNV 2.4) is the general standard marine navigation and communication equipment. It includes EMC and anti-vibration requirements. The requirement of anti-vibration needs to meet 0.7 g @ DNV 2.4 (Class A). It is according to a range between 3Hz ~ 100 Hz. Therefore, quality-assured marine devices need sophisticated design experience and specific know-how to select suitable components.
