IEC 60320-1:2015

Overview

IEC 60320-1:2015 - "Appliance couplers for household and similar general purposes – Part 1: General requirements" sets the safety, construction and testing framework for appliance couplers, including two-pole and two-pole-with-earth appliance inlets and outlets integrated in appliances. The standard applies to devices with a rated voltage up to 250 V (AC) and rated current up to 16 A. This third edition (2015) is a technical revision that replaces the 2001 edition and its 2007 amendment; it incorporates corrigenda up to May 2019 and clarifies requirements for non-standardized appliance couplers. Standard sheets for specific connector types have been moved to IEC 60320-3.

Key topics and requirements

IEC 60320-1:2015 defines general requirements and tests across these technical areas:

• Scope and classification of appliance couplers (two‑pole, with earth, rewirable/non‑rewirable)
• Marking and identification requirements, legibility and durability
• Dimensions and compatibility for mating connectors (standardized and non‑standardized)
• Protection against electric shock, accessibility of live parts and earthing provisions
• Terminals and cord connections, including cord anchorage and rewirable terminals
• Mechanical and thermal tests: temperature rise, heating tests, mechanical strength (impact, lateral pull, free fall)
• Insulation and dielectric strength, clearance and creepage distances, solid insulation
• Resistance to heat, ageing, moisture and tracking, and material flammability
• Forces for insertion/withdrawal and contact operation, contact pressure and pin retention
• Routine factory tests, proof tracking and electrical tests
• EMC considerations for accessories without electronic components

These topics mirror the document's table of contents and emphasize practical safety and interoperability checks required for appliance couplers.

Applications and who uses this standard

IEC 60320-1 is used by:

• Product designers and electrical engineers developing mains connectors, appliance inlets and outlets
• Manufacturers of household appliances, power cords and external power supplies to ensure safe connection to the mains
• Test laboratories and conformity assessors performing type and routine tests for safety and durability
• Regulatory and compliance teams preparing technical files for market access

Practical applications include design validation, type testing, QC routines for cordsets, and ensuring connectors meet safety, mechanical and environmental performance expectations.
