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.
3 Terms and definitions
IEC 60884-1:-, Clause 3 is applicable except as follows: Replacement of NOTE 3: NOTE 3 The term “accessory” is used as a general term covering socket-outlets and socket-outlets incorporating a USB power supply, the term “portable accessory” covers portable socket-outlets and portable socket-outlets incorporating a USB power supply, Add the following terms and definitions: 3.101 universal serial bus USB standardized bus using serial transmission [SOURCE: IEC 60050-171:2019, 171-04-48, modified – Note 1 to entry is deleted] 3.102 USB port IEC 62680 series female connector used to supply power to a connected portable device 3.103 USB power supply electronic circuit, including connections to the socket-outlet, PCB, connectors, internal wiring and similar that converts mains voltage into a lower voltage with smoothed direct current that is delivered through one or more USB port Note 1 to entry: USB connector types are defined in the IEC 62680 series. 3.104 SELV electric system in which the voltage cannot exceed the value of extra-low voltage: under normal conditions and – i under single fault conditions, including earth faults in other electric circuits Note 1 10 entry: SELV is the abbreviation for safety extra -low voltage. [SOURCE: IEC 60050-826:2004, 826-12-31, modified – “SELV system” has been replaced with “SELV”.] 3.105 hazardous live part live part with a voltage higher than 25 V AC or 60 V DC ripple free in dry conditions or 12 V AC or 30 V DC in wet conditions Note 1 to entry: Ripple free is conventionally an RMS ripple voltage not more than 10 % of the DC component. Note 2 to entry: For the purpose of this document, parts of the USB ports delivering SELV are not considered to be hazardous live parts as the output voltage of the USB remains below the limits of hazardous live parts. 3.106 rated output voltage voltage assigned by the manufacturer to USB port 3.107 rated output current current assigned by the manufacturer to USB port 3.108 rated output power electric power output assigned by the manufacturer to USB port Note 1 to entry: The rated output power is expressed in W. 3.109 maximum output power highest output power attainable from the USB power supply Note 1 to entry: The maximum output power can be different from the rated output power. Note 2 to entry: The maximum output power can be shared or cumulated through several ports.
9 Checking of dimensions
IEC 60884-1:- , Clause 9 is applicable except as follows: 9.1 General Add the following paragraph at the end of 9.1: Relevant mechanical dimensions of the USB connectors are given in the associated drawings in the relevant part(S) of IEC 62680. Mechanical interference between either the relevant plug(s) and the USB port(s) preventing their normal insertion and withdrawal or causing a partial insertion condition shall be prevented when considering basic plugs, and as far as possible when considering the wide diversity of adaptors and plugs shape. Compliance is checked by inspection and measurement in reference to the relevant standard sheet or USB connectors’ design. 9.3 Permitted deviations 9.3 is not applicable to USB connectors.
10 Protection against electric shock
IEC 60884-1:- , Clause 10 is applicable except as follows: 10.1 General Replace the first paragraph with the following: Socket-outlets shall be so designed and constructed that when they are mounted and/or wired as for normal use, hazardous live parts are not accessible, even after removal of parts which can be removed without the use of a tool. 10.2 Accessibility of live parts during normal use Add the following paragraph at the end of 10.2: 10.2 is not applicable to the accessible metal parts of USB ports.
