The GB/T 35552 standard, "Technical Requirements for Class B Equipment of Automatic Identification System (AIS) for Ships," aims to standardize the performance and specifications of Class B equipment.

The test requirements are for information processing and exchange between AIS devices and AIS base stations, and consist of two parts.

---Part 1: Carrier Sense Time Division Multiple Access (CSTDMA). The purpose is to specify the AISB class of devices employing CSTDMA technology.

The basic requirements for equipment include environmental, power supply, interference, safety, performance, and related testing requirements.

---Part 2: Self-Organizing Time Division Multiple Access (SOTDMA). The purpose is to specify the requirements for AISB class devices employing SOTDMA technology.

The basic requirements include environmental, power supply, interference, safety, performance, and related testing requirements.
