Perguntas frequentes:
  • What standards does the UL790 Test Machine comply with?
    The machine is designed to meet multiple international standards including UL790, ASTME108, NFPA256, and IEC61730-2 for fire resistance testing of roofs and solar panels.
  • How does the machine simulate real fire risks?
    It replicates two main fire scenarios: the Flying Fire Test simulates wind-blown burning embers on the roof, and the Flame Spread Test mimics flames from adjacent structures reaching the roof edge.
  • What are the key applications of this testing equipment?
    Primarily used for evaluating the fire resistance of roofing materials and photovoltaic cell components, it is essential for products requiring certification for markets in North America and other regions recognizing these standards.
