Hi Charlie,

Regardless of NFPA 79 being applicable or not, you will still want to select 
another product safety standard as NFPA 70 will not address the product 
completely.  I do not know enough about the product based on your description 
to suggest an appropriate standard.

Subject: [PSES] Scope of NFPA 79


All



I'm trying to determine whether a product falls within scope of NFPA79 for USA.



EU Machinery Directive determines whether a product is within scope by what it 
does, but my reading of NFPA79 is that the latter also considers "what it does 
it to".



Looking at the 2015 version, NFPA79, Chapter 3, section 3.3.54  defines 
'Industrial Machinery'  as:
" A power-driven machine (or group of machines working together in a 
coordinated manner),  not portable by hand while working, that is used to 
process material by cutting; forming;  pressure; electrical, thermal, or 
optical techniques; lamination; or a combination of these  processes. Machine 
can include associated equipment used to transfer material or tooling,  
including fixtures to assemble/disassemble, to inspect or test, or to package. 
[The associated  electrical equipment, including the logic controller(s) and 
associated software or logic together  with the machine actuators and sensors, 
are considered as part of the industrial machine.]"



The product in question processes gases (in silicon wafer and flat panel 
manufacturing plants) - so I don't think it processes "material".



If that is the case, it would be outside scope of NFPA79, and just within scope 
of NFPA70. Comments?



regards

Charlie
