This standard BS EN 62680-2-1:2015 Universal Serial Bus interfaces for data and power is classified in these ICS categories:
33.120.20 Wires and symmetrical cables
29.200 Rectifiers. Converters. Stabilized power supply
33.120.01 Components and accessories in general
29.220.01 Galvanic cells and batteries in general
35.200 Interface and interconnection equipment
IEC 62680-2-1:2015 defines an industry-standard USB. The specification describes the bus attributes, the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this standard. The goal is to enable such devices from different vendors to interoperate in an open architecture. The specification is intended as an enhancement to the PC architecture, spanning portable, business desktop, and home environments. It is intended that the specification allow system OEMs and peripheral developers adequate room for product versatility and market differentiation without the burden of carrying obsolete interfaces or losing compatibility.
