Chris, I'm copying a response I gave back in July on this subject. The R. Stahl link is very helpful.
Best regards, Dave 512.695.5871 www.lorusso.com ============================================================= This brings back a lot of memories; my first job out of college was with Factory Mutual Research Corporation (www.fmglobal.com) doing hazardous location approvals. Instead of reinventing the wheel (and digging deep into memory), here's a link to an excellent primer on explosion protection by R. Stahl, one of my first clients. 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. Good luck and best regards, Dave Lorusso Lorusso Technologies, LLC www.lorusso.com 512.695.5871 ============================================================ ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
