Fire Extinguishing Performance Test Equipment

What is the Fire Extinguishing Performance Test Equipment？

ZONSKY Standard Fire Extinguishing Test for Class A Fires apparatus is designed to assess the effectiveness of fire extinguishing agents on Class A fires, which involve combustible materials such as wood, paper, and textiles. This test apparatus evaluates extinguishing performance by measuring factors such as discharge rate, coverage area, and suppression time, ensuring compliance with the GB4066-2017 standard. Fire Extinguishing Performance Test Equipment
