IEC 60227-5:2024

Overview

IEC 60227-5:2024 is the International Electrotechnical Commission (IEC) standard that specifies particular requirements for polyvinyl chloride (PVC) insulated flexible cables (cords). Part 5 of the IEC 60227 series supplements the general requirements in IEC 60227‑1 and applies to flexible cords used at low voltages. The IEC 60227 series covers PVC insulated cables up to 450/750 V, while Part 5 provides the particular specifications for flexible cords (the scope specifically refers to rated voltages up to and including 300/500 V). Test methods referenced in this part are described in IEC 63294.

Key topics and technical requirements

The standard addresses the essential elements manufacturers, test laboratories and compliance bodies need for safe, reliable flexible cords:

• Code designation and rated voltages for different cord types
• Construction requirements including conductors, insulation, core assembly, fillers and overall dimensions
• Sheath specifications where applicable (light, ordinary and heat‑resistant PVC‑sheathed cords)
• Specific cord types covered: flat tinsel cord, cords for indoor decorative lighting chains, light PVC‑sheathed cords, ordinary PVC‑sheathed cords, and heat‑resistant cords (conductor temperature up to 90 °C)
• Mandatory tests and test procedures such as bending/flexing tests, drop tests, long‑term insulation resistance (d.c.), and other type‑specific mechanical and electrical tests
• Guidance on use for each cord type and tabulated data (general data and tests) to support selection and verification

Practical applications

IEC 60227-5:2024 is directly applicable to:

• Manufacturers of appliance and equipment cords, decorative lighting chains and flexible power cords
• Product designers and OEMs specifying flexible PVC cords for consumer and commercial products
• Testing and certification laboratories performing compliance and type approval testing
• Procurement and regulatory teams validating that supplied cords meet international safety and performance requirements

Using the standard helps ensure product safety, interchangeability and regulatory compliance, and supports consistent testing and quality control across suppliers and markets.

Who should use this standard

• Cable and cord manufacturers
• Test labs and conformity assessment bodies
• Electrical safety engineers and compliance officers
• Product designers, OEMs and procurement professionals
