Thanks for your answer, there is no any explosive F.E. in NFPA 10, therefore, I think even it can't get approval under NFPA 10. I found some spec. about size of fireball in NFPA 68. Is it included in NFPA 68?
1.1* Scope. This standard applies to the design, location, installation, maintenance, and use of devices and systems that vent the combustion gases and pressures resulting from a deflagration within an enclosure so that structural and mechanical damage is minimized
Just briefing through NFPA 10, I am thinking no they would not meet NFPA 10 standards.
1. They have to be tested and listed by an agency, that is approved in NFPA 10.
2. Depending on the size of the fire extinguisher, it appears there is a minimum discharge duration, Which sure these do not meet.
