Intrinsic Safety - Aluminum
Intrinsic Safety - Aluminum
(OP)
I understand Aluminum is bad in an explosive environment because it can spark when other metals are dragged against it.
IEC 60079-0:2007 clause 8.1.2 states that in 'Group II protection level Ga (ia)' the enclosures can't be more than 10% aluminum. I see Rose Enclosures is selling Aluminum enclosures that they claim are safe for 'ia' applications (http://www.rose-bopla.com/Prod_Pgs/Ex/Prod_06_Alum...). Am I missing something that Aluminum is safe, or did Rose marketing get a bit overzealous? I notice that the certificates available on the web don't claim 'ia'.

IEC 60079-0 Clause 8.1.2 states that Group II Ga enclosures "shall contain not more than 10% in total of aluminum, magnesium, titanium, and zirconium, and not more than 7.5% magnesium, titanium, and zirconium". Are they restricting the combinations, not an individual component (such as Aluminum)?
