Overview
IEC 60332-1-2 specifies a method to assess the flame propagation characteristics of a single insulated wire or cable under controlled fire exposure. It evaluates whether the cable can resist flame spread and self-extinguish after ignition.
This standard is widely used in the electrical, cable manufacturing, and construction industry to ensure fire safety of cables used in buildings, infrastructure, and industrial installations. It plays a crucial role in minimizing fire hazards and ensuring compliance with safety regulations for electrical systems.

Frequently Asked Questions
IEC 60332-1-2 is used to evaluate the flame propagation characteristics of a single insulated wire or cable, helping determine its ability to resist fire spread and self-extinguish under controlled fire exposure conditions.
Flame propagation testing is essential to ensure that cables do not contribute significantly to fire spread, thereby improving safety in buildings, industrial systems, and infrastructure installations where electrical wiring is present.
By ensuring cables resist flame propagation, it reduces the risk of fire spreading through electrical wiring systems, enhancing overall building safety.
Factors such as insulation material, cable design, thickness, additives, and flame exposure duration significantly affect how a cable reacts to fire and its ability to limit flame spread.
Char length represents the extent of damage caused by flame exposure along the cable. It is a key parameter used to determine compliance, as excessive char length indicates higher flame propagation and reduced fire resistance performance.
