IEC 60320-2-1:2000 is applicable to special purpose appliance couplers for household sewing machines. These sewing machine couplers are for a.c. only and have a rated voltage not exceeding 250 V and a rated current not exceeding 2,5 A. The sewing machine couplers may include two or more contacts depending on the control components or circuitry required to operate the sewing machine and may be with or without earthing contact. This second edition cancels and replaces the first edition published in 1984. This part 2 is to be used in conjunction with IEC 60320-1: Appliance couplers for household and similar general purposes - Part 1: General requirements. It was established on the basis of the first edition of that standard (1994) and its amendments 1 (1995) and 2 (1996).
