IS/IEC 62368-1:2023 for Docking Stations and USB Hubs

IS/IEC 62368-1:2023 for Docking Stations and USB Hubs

Laptop docking stations, USB hubs, and multi-port adapters require BIS CRS registration under IS/IEC 62368-1:2023 (migrating from IS 13252). With the proliferation of USB-C docks and multi-port adapters, this category has grown significantly.

Products Covered

  • Laptop docking stations (USB-C and Thunderbolt)
  • Multi-port USB-C adapters / hubs
  • USB-A powered hubs
  • Monitor docking stations
  • KVM (Keyboard-Video-Mouse) switches

Power Classification

Standard USB-A powered hubs (5V/2.5A): PS1 or low PS2 — minimal requirements, straightforward migration. USB-C Power Delivery pass-through docks (which charge the connected laptop while also powering displays): power can reach 90-140W — PS2 or approaching PS3. High-performance docking stations with dedicated GPU and extensive display output can significantly exceed 100W.

USB-C PD Pass-Through Safety

Docking stations that pass USB-C Power Delivery through from a charger to a laptop are a new product type not covered in IS 13252 (IEC 60950-1 era). IS/IEC 62368-1:2023 specifically addresses USB-C PD, including pass-through configurations. The evaluation must address:

  • Maximum PD wattage the dock can pass through
  • PD negotiation failure scenarios
  • Thermal performance of the PD circuit under maximum load

Multiple Display Output

Docks with HDMI and DisplayPort outputs for multiple external displays: the video output circuits require evaluation under IS/IEC 62368-1:2023 for isolation and safety of the video data interface circuits.

Migration

Standard USB hubs: 6-8 week migration. High-power USB-C docks with PD pass-through: 8-12 weeks due to USB-C PD evaluation. Deadline: November 2028. HOT handles IS 62368 docking station and USB hub testing.
