EN 60332-1-2 Cable Flammability Test – Overview
EN 60332-1-2 evaluates the fire performance of insulated electrical cables by assessing their resistance to flame propagation under a defined ignition source. It determines whether a single cable can self-extinguish after exposure to a controlled flame.
This test is critical for ensuring fire safety in electrical installations, as it verifies that cables do not contribute to flame spread. It is widely applied in building, industrial, and infrastructure wiring systems for compliance and safety assurance.
Scope, Applications, and Benefits
Scope
This test method defines procedures to assess the vertical flame propagation characteristics of a single insulated wire or cable under controlled flame exposure. It evaluates ignition behavior, flame spread, and self-extinguishing capability.
The method ensures cables meet minimum fire safety performance requirements.

EN 60332-1-2 Cable Flammability Test – Test Process
Sample Preparation
A single cable or insulated conductor is mounted vertically in the test apparatus.
1Flame Application
A standardized burner flame is applied to the cable for a defined duration.
2Flame Propagation Observation
The flame behavior and the extent of vertical propagation along the cable are observed.
3Data Recording & Evaluation
Flame spread distance and burning behavior are measured and evaluated in accordance with the standard.

Frequently Asked Questions
The test EN 60332-1-2 is used to determine the resistance of a single insulated electrical cable or optical fiber cable to the vertical flame propagation when it is subjected to a flame in a laboratory fire safety test.
In EN 60332-1-2, the test cable is subjected to a standardized burner flame in a specified time duration. After the removal of the flame, technicians observe the self-extinguishing of the cable and the flame spread.
EN 60332-1-2 is used to ensure that the cables are safe from the propagation of flames over a large length of the cable. This improves safety in buildings, industries, and infrastructure, where electrical cables are installed.
EN 60332-1-2 applies to single-insulated electric cables, power cables, control cables, communication cables, and optical fiber cables in buildings, transportation systems, and industrial electric installations where fire performance verification is required.
The standard EN 60332-1-2 tests for flame propagation in a single cable and does not represent the behavior of a bundle of cables in a fire situation, smoke production, or toxic gas emission.
