Flame retardant: The core is "non spreading". After ignition, the flame only burns within a limited range and can extinguish itself after leaving the source of fire, preventing the fire from spreading. Commonly used for wiring in densely populated buildings.

Fire Resistant: The core is' able to maintain '. In a flame burning environment, it is still possible to maintain the integrity and electrical function of the circuit within the specified time (such as 90 minutes), in order to buy time for firefighting and evacuation. Commonly used in lifeline engineering such as fire protection systems and emergency lighting.

Simple note: "Flame retardant" is to protect the surrounding area, while "fire-resistant" is to ensure that oneself works in a fire.
