__________________________________________________ The Canadian Standards association published a book "Hazardous Locations, A guide for the design, construction and installation of Electrical Equipment. It was written Pre-ATEX Directive, and I do not know if it has been updated since then, but I find that it is a great reference document. __________________________________________________ ... an excellent primer on explosion protection by R. Stahl .. http://www.rstahl.com/Exprotection/index.htm Click on the pdf "Basics of Explosion Protection" for an in depth look at this subject. It's about 4.5 Mb. The answers to your questions are in there plus a whole lot more. _________________________________________________ The best resource I know of is Factory Mutual Research, Most of their standards are free or extremely cheap. And they always answer the phone. I am told they also are good with email, although I haven't bothered to test that. _________________________________________________ Consider "Intrinsically Safe Instrumentation Guide" Robin Garside, Hexagon via RS components 907-894. ________________________________________________ Web source: Dr. -Ing.
