Does anyone know whether brass really is non sparking if there is
friction with other materials? until now I alwas used brass for a
coupling guard in hazardous areas (gas / dust in chemical industry).
The Coupling is made of steel or stainless steel, about 400kgs in
wight and rotating with up to 2000rpm. It is protected through my
guard (a simple box made of brass). But what happens if there is any
defect and the coupling touches the guard? Will there be sparks or
Is there any norm (EN / ISO etc.)?
Thanks in advance!
