Here’s an illustration that provides an answer:
Consider a highway and a vehicle. Two separate entities.
Highways get specified speed ratings based on many factors - curves, lane count, expected traffic, road surface, terrain, etc.
The Governing body assess these factors and determines the speed limits . . . they “Rate” the roadway setting speed limits based on known factors.
are applied. These
are rated completely differently. They must meet Federal Motor Vehicle Safety Standards, a completely different set of safety system criteria.
So – to answer the question(s) . . .
- Buildings are rated by the NFPA depending on their use.
- Paint Spray Booths have their own Safety Code (NFPA 33).
- LED fixtures are tested and rated using the NEC Codes – which is a different safety rating system.
I hope this helps,
