Overview

IEC 60245-8:2026 is an internationally recognized standard published by the International Electrotechnical Commission (IEC). It specifies the requirements for rubber insulated and textile braid covered cords, with a rated voltage of 300/300 V, designed for applications demanding high flexibility-such as iron cords. These cords are intended for use where repeated movement or bending is common, making flexible cable performance critical for safe and reliable operation. This standard is to be used in conjunction with IEC 60245-1, which outlines the general requirements for all cables in the IEC 60245 series. The testing procedures relevant to these flexible cords are detailed in IEC 63294.

Key Topics

• High flexibility: Defines construction requirements for cords subjected to frequent bending and movement.
• Rubber insulation: Emphasizes the use of EPR (ethylene propylene rubber) compounds that provide durability and electrical safety.
• Textile braid covering: Outlines specifications for textile braid coverings, improving mechanical strength and flexibility.
• Testing requirements: Details comprehensive electrical, mechanical, and thermal tests to ensure cable safety and performance.
• Updates in Edition 2.0:
  • Test references changed from IEC 60245-2 to IEC 63294.
  • Removal of references to lift cables from IEC 60245-5.
  • Updated normative references to reflect the latest standards.

Applications

IEC 60245-8:2026 cables are suitable for a variety of applications where high flexibility and durability are essential:

• Household appliances: Especially irons and other devices requiring movement during operation.
• Portable tools: Electric tools and appliances that involve frequent handling and flexing.
• Mobile and temporary installations: Extensions where cables are wound and unwound frequently.
• Commercial and industrial environments: Where cords may be subject to mechanical stress and small bending radii.

Adherence to this standard ensures safety, longevity, and optimal electrical performance in demanding environments where flexible cords are exposed to continuous mechanical stress.

Practical Value

Implementing IEC 60245-8:2026 provides several key benefits:

• Enhanced safety: Rigorously tested materials and constructions help minimize fire and electrical hazards.
• Product reliability: Ensures cords withstand frequent flexing and tension, reducing failures and downtime.
• International compatibility: Facilitates global trade and acceptance by aligning products with internationally recognized safety and performance requirements.
• Reduced maintenance: Cords performing to this standard require less frequent replacement due to wear or mechanical failure.

Related Standards

When working with or specifying cords according to IEC 60245-8:2026, the following standards are particularly relevant:

• IEC 60245-1: General requirements for rubber insulated cables up to 450/750 V.
• IEC 60228: Conductors of insulated cables-requirements for conductor classes and performance.
• IEC 63294: Test methods for electric cables up to and including 450/750 V.
• IEC 60811-401, -403, -412, -501, -507: Various test methods for the mechanical and thermal properties of non-metallic cable materials.
• IEC 62440: Guidance on the safe use of electric cables with rated voltage up to 450/750 V.

By following IEC 60245-8:2026, manufacturers and users can ensure high-performance, flexibility, and compliance in applications where cable movement and durability are essential. This fosters safe, efficient, and cost-effective operation in both domestic and industrial settings.

shall be as specified in Table 2 Table 4.
5.4.34.4.4 Kink test
4.4.4.1 General
This test shall be carried out in accordance with 3.6 of IEC 60245-2 IEC 63294:2021, 6.13.
Test current and tensile force shall be as specified in Table 2.

5.4.3.14.4.4.2 Sample
In order to prevent the tensioning weight reaching the top of its guide and either hitting an end-
stop or rising clear of the guide, the following sample preparation shall be carried out prepared
as follows:
a) the three twists shall be set in the sample and temporarily secured with adhesive tape before
presenting positioning the sample to on the equipment;
b) the ends of the sample shall be located in the fixing clamps and the adhesive tape shall
then be removed;
c) the fixing clamps shall be slowly moved apart to ensure that the sample achieves a straight
orientation when the clamps are fully extended, with the tensioning weight still in the guide
and satisfying complying the 50 mm lift specified in 3.6.4 of IEC 60245-2 IEC 63294:2021,
6.13.4. When the fully extended position is reached, the tensioning weight shall not make
contact with any end-stop in the guide;
d) if this straight orientation is not achieved, up to 30 slow test cycles shall be performed
during which the sample shall be manipulated to distribute twists more evenly over the sample
length and so that a knot does not occur to avoid the creation of knots during the initial phase
of the test procedure.
5.4.3.24.4.4.3 Requirements Test procedure
A total of 1 500 cycles shall be made on each sample.
54.5 Guide to use (informative) Guidance on use of the cables
The use of cable type 60245 IEC 89 shall comply with IEC 62440, which provides guidance on
the safe use of electric cables with a rated voltage not exceeding 450/750 V.
Maximum conductor temperature in normal use: 60 °C.
NOTE Other guidelines are under consideration.
