Needle Flame Test Apparatus IEC 60695-11-5 for Insulating Materials Fire Resistance
The Needle Flame Test Apparatus is a precision laboratory instrument designed to evaluate the fire resistance of insulating materials and small components. This equipment simulates localized flame conditions that may result from electrical faults, overheating, or component failures in electrical and electronic products.
Manufactured in strict compliance with IEC 60695-11-5 standards, this apparatus provides controlled, repeatable testing for ignition behavior, flame spread, and self-extinguishing performance. It is widely utilized in safety compliance testing, product development, and quality inspection laboratories.
