A question to members of this forum.
NFPA describes "Listed" as Equipment included in a list published by an organization that is acceptable to the AHJ. OHSA (under United States department of Labour) mention a number of various NRTL's here among FM, UL, TÜV etc.
Do anyone know if its acceptable to design a Fire fighting system using different NRTL's. For instance a foam inductor, nozzles and foam concentrate UL approved along with FM approved Bladder tank?
Thanks in advance.
