An AIS (Automatic Identification System) transceiver or receiver automatically sends and receives vessel identity, position, speed and course information to improve navigation safety and collision avoidance. AIS equipment must meet international performance and type-test standards such as IEC 61993-2 (Class A) and IEC 62287-1 (Class B).

To ensure safety and regulatory compliance, AIS enclosures are tested to the IEC 60529 Ingress Protection (IP) standard, which defines how well devices resist dust and water ingress. Common marine IP targets for AIS and other marine electronics are IP65, IP66, IP67 or higher.
