IEC 60320 is an international standard published by the International Electrotechnical Commission (IEC), titled "Appliance couplers for household and similar general purposes". It specifies the dimensional, electrical, and safety requirements for couplers used to connect power supply cords to electrical appliances, covering voltages up to 250 V a.c. and currents up to 16 A. The standard is divided into several parts, with the most important being IEC 60320‑1 (General requirements), which has undergone multiple revisions: the first edition was published in 1994, the second in 2001, the third in 2015, and the latest effective edition is the fourth edition, IEC 60320‑1:2021, released on 27 July 2021. Additional parts include IEC 60320‑2‑X series for specific applications (e.g., sewing machine couplers, couplers with higher IP ratings) and IEC 60320‑3 for standard sheets and gauges.
