1 Scope
IEC 60884-1:-，Clause 1 is applicable except as follows:
Replace the first paragraph by the following:
This part of IEC 60884 applies to fixed or portable socket-outlets for AC only, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 32 A, intended for household and similar purposes, either indoors or outdoors, incorporating a USB power supply.
This document defines the safety and EMC requirements for socket-outlets incorporating a USB power supply.
Specifications, performance and dimensional requirements of the USB technologies are not covered by this document; these are defined in the relevant part(s) of IEC 62680.

13.101 Conductors used in a USB power supply
Internal wiring that is accessible during and/or after installation, if any, shall be secured in such a way that it cannot become loose or detached and impair the safety of the accessory.
Conductor terminations using solder shall be mechanically secured. Hooking the conductor through a hole of the conductive termination and affixing conductors in thermal tubing, sealing compound or glue are examples of acceptable securement.
This requirement is not applicable to internal wiring that cannot be so displaced such that clearances or creepage distances are reduced below the specified values or such that, if it becomes loose, it cannot create hazardous connections between primary and secondary circuits.IEC 60884-3-1 pdf download.
