How to Download IEC 60840 PDF for Free: A Guide for Electrical Engineers
IEC 60840 is an international standard that specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to 150 kV (Um = 170 kV). The standard covers single-core cables and individually screened three-core cables and their accessories for usual conditions of installation and operation. The standard does not apply to special cables and their accessories, such as submarine cables, or to transition joints between cables with extruded insulation and paper insulated cables.

The standard does not apply to special cables and their accessories, such as submarine cables, or to transition joints between cables with extruded insulation and paper insulated cables.
In this article, we will explain what IEC 60840 is, what it covers, why it is important, and how you can download it for free. We will also provide some tips on how to use the standard effectively and safely.
What is IEC 60840?
IEC 60840 is an international standard that was first published in 1988 by the International Electrotechnical Commission (IEC), which is a non-profit organization that develops and publishes international standards for electrical, electronic and related technologies. The standard has been revised several times since then, with the latest edition being published in 2020. The standard is available in English and French languages.
IEC 60840 provides detailed guidance on the performance and quality of power cables and accessories, as well as the methods to verify their compliance with the specifications. The standard also includes information on the environmental conditions, fire performance, water penetration, bending test, electrical test, thermal test and mechanical test of power cables and accessories.
The standard applies to power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to 150 kV (Um = 170 kV). The standard defines the following terms:
Power cable system: a combination of one or more power cables with their accessories.
Power cable: a cable designed to carry electric power.
Accessory: a device that enables one or more power cables to be connected together or to other equipment.
The standard does not apply to special cables and their accessories, such as submarine cables, or to transition joints between cables with extruded insulation and paper insulated cables. The standard also does not cover the installation of power cable systems or the operation and maintenance of power cable systems.
What does IEC 60840 cover?
IEC 60840 covers the following aspects of power cable systems, cables alone and accessories alone:
General requirements: these include definitions, symbols, units, reference standards, classification of tests, sampling procedures, test reports and certificates.
Cable construction: these include materials, dimensions, tolerances, markings and identification.
Cable characteristics: these include electrical characteristics (such as rated voltage, insulation level, conductor resistance, capacitance, inductance), thermal characteristics (such as maximum conductor temperature, short-circuit temperature), mechanical characteristics (such as tensile strength, elongation) and environmental characteristics (such as resistance to water penetration).
Cable tests: these include type tests (such as electrical tests at ambient temperature or elevated temperature), routine tests (such as partial discharge test), sample tests (such as bending test), prequalification tests (such as thermal cycling test) and after installation tests (such as voltage test).
Accessory construction: these include materials, dimensions, tolerances, markings and identification.
Accessory characteristics: these include electrical characteristics (such as rated voltage, insulation level), thermal characteristics (such as maximum conductor temperature), mechanical characteristics (such as tensile strength) and environmental characteristics (such as resistance to water penetration).
Accessory tests: these include type tests (such as electrical tests at ambient temperature or elevated temperature), routine tests (such as partial discharge test), sample tests (such as bending test) and after installation tests (such as voltage test).
The standard also provides annexes that give additional information on topics such as gas immersed cable terminations, composite outdoor termination insulators, low smoke halogen free oversheath material ST12, fire performance tests and water penetration test in the conductor.
Why is IEC 60840 important?
IEC 60840 is important because it provides a common framework for the design, manufacture, testing and certification of power cable systems,
cables alone and accessories alone for rated voltages above 30 kV (Um = 36 kV) up to 150 kV (Um = 170 kV). The standard helps to ensure that power cable systems are safe,
reliable,
efficient
and compatible
with other equipment
and systems.
The standard also helps to facilitate international trade
and cooperation
by harmonizing the technical requirements
and specifications
of power cable systems across different countries
and regions.
