GV-JR-NJW-CE Vertical Loading Fire Resistance Test Furnace
Introduction
According to fire safety requirements, various components such as fire doors, windows, rolling shutters, fire-resistant glass, firewalls, non-load-bearing vertical partition elements, load-bearing vertical partition elements, and columns should undergo fire resistance limit testing. In accordance with the national standard GB/T 9978-2008, fire performance tests should use open-flame heating to subject the test specimens to conditions similar to those in actual fires. This test furnace simulates the actual temperature rise process during a fire, meeting the requirements for fire resistance limit testing and providing a comprehensive evaluation of the component’s fire performance.
