IEC cable 60332
The NORME IEC 60332 was established by the International Electrotechnical Commission (IEC). It defines the test methods of the flame resistance of the electric cables. The objective is to evaluate the ability of the cable to delay the spread of fire, thus guaranteeing the safety of buildings, public infrastructure and industrial facilities. A cable compliant with IEC 60332 is considered a flame retardant cable (flame delayer). These cables are widely used in projects where fire safety is paramount.
At ZMS Cable, we offer a wide range of cables compliant with the IEC standard 60332. These cables are fire resistant, safe and durable.
What's more, ZMS Cable offers custom cabling solutions to meet the specific needs of each project.
ZMS supplies IEC compliant cables 60332
IEC standard 60332 is not unique, but brings together several test methods to evaluate the flame resistance of electrical cables.
The three most used classifications are : IEC 60332-1, IEC 60332-2 and IEC 60332-3, each corresponding to a different level of fire safety requirements.
IEC cable 60332-1 – Flame resistance test on an individual cable
The IEC cable 60332-1 is intended to test the fire resistance of an individual cable. During the test, the cable is suspended vertically and exposed to a small flame for 60 or 120 seconds, according to its external diameter. To be compliant, the flame should go out on its own after the source is removed, and the combustion length must not exceed the limit set by the standard. Our experts recommend the use of IEC cables 60332-1 in residential buildings, commercial and public, to ensure effective protection against the spread of flames.

IEC cable 60332-2 – Flame resistance test on a small cable bundle
The IEC cable 60332-2 applies to small cable bundles arranged vertically. During the test, a small group of cables is exposed to a standardized flame for approximately 20 minutes. The objective is to evaluate whether the fire spreads through the beam or whether it goes out on its own after the flame goes out.. To succeed, vertical propagation must remain limited and not exceed the defined maximum height. Our experts recommend that cables conforming to IEC 60332-2 are installed in industrial infrastructures, transport networks and technical sites requiring enhanced fire safety for small cable bundles.

- Its small diameter facilitates installation in narrow cable trays or confined spaces.
- Good compromise between performance, flexibility and reliability for communication infrastructures.
- Less suitable for energy transport or direct control of machines, where the use of an IEC control cable 60332-2 is preferable.
IEC cable 60332-3 – Flame resistance test on a large cable bundle
The IEC cable 60332-3 evaluates the fire resistance of large cable bundles installed in layers. The sample is mounted vertically and exposed to a powerful flame for 20 has 40 minutes, according to test category (A, B, C or D). The main criterion is that the vertical propagation of the flames remains below the maximum height imposed by the standard.. Our experts believe that IEC cables 60332-3 particularly suitable for tunnels, to the metros, to power plants, at airports and other critical projects requiring optimal fire safety.

IEC Cable FAQ 60332
1. What is an IEC cable 60332 ?
An IEC cable 60332 is an electrical cable designed and tested according to the international IEC standard 60332, which defines the resistance to flame propagation. These cables are essential to limit the risk of fire in electrical installations.
2. What is the difference between IEC 60332-1, IEC 60332-2 and IEC 60332-3 ?
- IEC 60332-1 : flame resistance test on a single cable.
- IEC 60332-2 : test on a small wiring harness.
- IEC 60332-3 : test on a large cable bundle.
The choice depends on the installation environment and the required level of security.
3. Where are IEC cables used? 60332 ?
IEC fire resistant cables 60332 are used in public buildings, Tunnels, airports, energy networks, telecommunications systems and any project requiring increased protection against fire.
4. IEC cables 60332 are they fire resistant cables (fire resistant) or flame retardant cables (flame retardant) ?
IEC cables 60332 are flame retardant cables (flame retardant cables). This means they slow or prevent the spread of flames when exposed to fire. On the other hand, fire resistant cables (fire resistant cables, tested according to IEC 60331 For example) are designed to continue operating during a fire, ensuring the power supply or transmission of critical signals.
SO,
IEC 60332 = flame retardant → limits the spread of the fire.
IEC 60331 = fire resistant → maintains operation under fire.
5. IEC cables 60332 are they the same as LSZH cables (Low Smoke Zero Halogen) ?
Non. LSZH cables mainly concern the reduced emission of smoke and toxic gases in the event of fire, while IEC cables 60332 are certified specifically for their resistance to flame propagation. Often, both features can be combined in the same cable for maximum safety.
